Comfy slippers on - Charlie's back with more amazing engineering for model railways. Makes Fridays worthwhile as always. Thanks Charlie - great to see the helix taking shape.
FYI, I used that screw method to hold my HO track in my helix and to hold my 45mm gauge track in my backyard. It works in both places! And, my outdoor track is subject to temps from near freezing to 120F. It allows the tracks to expand and contract without any problem. Brilliant!
DCC Concepts Powerbase works by fitting the supplied magnets to the underside of locomotives. This enhances grip, pulling the loco down onto the track.
It's amazing all the details involved in building one of these monsters. I'm intrigued by the Powerbase. Over here, we just cut in a couple of "B" units! Seriously, that is a great solution to the problem. Really enjoying this build. Thanks for letting us watch!
Very good demonstration. I did not consider a helix in the past, but with a new basement, I need one or two now. Thank you for this great demonstration.
Many years ago I unsuccessfully tried to build a "rabbit" in Z gauge for my youngest twins, and stumbled repeatedly over the gradients. I eventually concluded it was far too much for my limited skillset, (even then it'd been years since I'd done much modelling beyond some first fix on a club layout with the lad between the sets of twins), and gave up...totally...so I thought this might offer my addled mind some explanation for my failings...and it did...but my god you must have a convoluted mind and the patience of a saint! Thank you for such a clear explanation, and I'm watching this build with fascination! Dave
Great stuff Charlie - I constructed a helix, single track with a gradient of 1:45 and my Hornby HST flies up it with seven coaches! It really is a powerful loco. Some of the steam locos need banking but in general all the diesels cope with it - even my 1970s Lima Westerns!
Charlie, that was the most enjoyable, fascinating and compelling video I have watched for a very long time. All your videos are a joy to watch, but this one was something really special. I'm unlikely to ever have a model railway of my own so I've adopted Chadwick as my virtual layout. Thank you for all your work, wisdom and endless gentle good humour. The internet is better place for your presence.
Threaded rod is a sensible choice. US practice seems stuck on using 1x2 "ladders." These are often made in batches with the level-to-level rise uniformly applied. The base legs are then trimmed to create the slope. US practice often uses "door skins" (sheets of either bidirectional or unidirectional plywood meant to face residential panel doors; available cheaply) to cut the entire 360º, which is threaded onto the ladders. Handy part with all that is having a central "man access" to the assembled helix. But, such things are simpler with the sort of manpower a club layout enjoys.
Nice!! That helix alone would be a big conversation piece for visitors to your layout. Another greatly informative video, sir. Cheers from the States. Stay safe.
I never thought I would see the day that this happens, but screws and track on this channel!! Great video as always, looking forward to seeing it in place!
Another great and informative video, really enjoying this new build of yours.. Add a webcam for when its up and running so those of us who can't have one get to see you operate and enjoying yours 🙏.
Thanks Charlie, looking really good. The calculations look complicated but with some time and effort they are ok. Looking forward to the next one. regards Gareth
A very complex project which obviously requires an understanding of math/geometry but Cad and manufactured curves obviously help not to mention the enormous expense, time and effort. Well done👍
Thank you for a guide through what is a fascinating and devilishly complex list of requirements, for letting us see its complexities and the keen advice you provided too. Always an education on your channel as well; I can't list the confidence I've gained in areas of worry to me on here, just in building a more standard layout m'self. I do hope it all goes back together with less fuss when you re-install it in your own Railway Room. Stay Safe and Keep Well, sir.
About access, I noted that on many (if not any) professional /public opened layouts, the helixes are hollowed out in the middle to allow an easier access ro the tracks for repair and maintenance. Not forgetting the lighter construction, the quantity of wood saved and a much easier handling when installing and/or eventual moving the whole construction...
Another great video Charlie - thank you. It's looking good. A couple of things I learnt when I built my last layout which incorporated a similar Helix with threaded rods and nuts (albeit Swiss narrow gauge single track). I deliberately incorporated some super elevation (cant) into the track sub-bed (giving me 0.8mm across the 12mm gauge track) I started with the track level, and then worked my way around to get it adjusted correctly, time consuming but straightforward (Trains (no steam locos) run perfectly with a 380mm radius curve and a 4.5% grade) I also elongated the holes through which the rods pass to reduce the stress in the sub-bed because if you look at the vertical geometry the sub-bed is the long side (hypotenuse) of a right angle triangle. With only a 2% grade and a larger radius the difference is small but not insignificant and you may find that when complete the threaded rods are not be vertical, which of course isn't an issue if they are out of sight. Just my 2p worth but hopefully useful. Take care and keep safe john c
Very interesting points John, thank you. Yes I thought of adjusting some cant on the bed which I can do towards the end of the build. Elongated holes is in a good idea and perhaps one we should look into. Regards Charlie
@@ChadwickModelRailway Sorry I forgot to mention that with my 4.5% grade I also had to use tapered wooden washers above and below the track sub-bed because when I tightened the nuts above and below they tried to flatten the sub-bed. With a 2% grade this will not be so noticeable but don't over tighten them because the clamping effect will be to flatten the sub-bed.
This is an amazing project and very enjoyable to watch an explained very well. Having a double Helix opens up so many running opportunities and I guess continuous running? So there will be double track underneath the mainboard connecting the two and some sort of crossover.
Hi Charlie, congratulations on what, to me, appears to be a massive undertaking. In some ways it takes me back to my childhood when putting Meccano pieces together if that make sense. I will continue to follow with great interest the Helix being assembled. Again stay safe Cheers Greg
Charlie... get a small round kitchen sponge, put a nut and bolt through the middle of it and then put the bolt in the chuck of your drill... then use it and the drill to wind down all then threaded bar bolts by using the side of the sponge to the side of the nut.. if that makes sense. Stu
Simple, very simple, but very clever. I love it. 😁👍👌 Not really worth the effort for a couple of nuts but, for a project like this, that wee idea could save 𝐚 𝐥𝐨𝐭 of time and a couple of blisters.
Hi Charlie, very informative and great video to show the fine details required and possible issues in helix building. Planning and thought is most definitely the key here!! Thankfully I haven't had the need to install one and not sure I would have the stomach to tackle one lol cheers, Derek.
Hi. very impressive and informative. You mentioned about the track being level. In real life, tracks are at an angle in curves to compensate the centripetal force of the train and helps also to keep the train not slowing down. In my curves, the first 30cm of curve track is not glued to the track bed, but then for all of the curve length ( except the last 30cm ), i elevate the outer track just 1 to 2 mm from the inner one. It works really fine.
Hi Charlie..... All looks to be coming together just fine. All the research.parameters etc spot on and explained well. Something worth considering when finished is to make up a control train.... loco plus a load of rolling stock that can just make it up the helix without wheel slip. Keep this train as a unit train or take note of it's makeup, throttle setting etc maybe also. First run: Track must be 'virgin' ... clean as possible and shinny. (Track could be washed in your sink maybe as you assemble helix's. [G} ). Reason I pass this on is as you use the up helix performance will change depending on how you clean the track or run your trains. The control train gives you a base to compare performance against later on. You may get a few surprises depending on how you treat your track.
Hi Charlie another great video mate great information on binding your helixs I really injoyed it so much I am looking forward to see them on your layout and seeing trains runing on them it will be every interested keep up the great work mate stay safe and well mate goodbye for now Clive
Very nicely done. I love it. My question is if the rise of each round is the same why done we cut a piece of pipe of the high and place it in the rode under each board so turnings the nuts height would be easier.
That's certainly a major project which requires plenty of skill. My layout wouldn't benefit from a helix and if it did I wouldn't attempt to build one. It's about knowing your limits and for me it's certainly off limits. Hats off to you and a very interesting watch
Fully makes sense on your mathematics, I wish I had seen a video like this before I built mine. Great detail and reasons why you are using Power Base (magnets) on up track, looking forward to seeing helix in place..
I have long fantasized running a train around the house above the window frames, bringing it down wherever it was convenient. a Helix would get the train up there!
Nice video. Great to see such a full treatment. When watching the spreadsheet work at 9:00 as you cranked up the revolutions to cover the 18 inches to get the grade down, I became worried as you were not watching the elevation gain per revolution. It’s all nice on paper but in that One revolution you have to get the loco and cars in there by height so the roof doesn’t hit the bottom of the next revolution. 3.27 inches is what you computer. That’s going to be a very tight squeeze for OO locos. Not running electrics the pantograph issue doesn’t come into play. But you still will want the space to be such that you can get your hand in there to address an issue if needed between the levels. So my recommendation to folks is to build it to the lowest height that will work for your locos (tallest loco with pantos up if your need that) and still allow your fingers over the loco so you can pick it up and place it back. That sets the minimum gap per revolution. The room then likely sets the radius of the circle, of the grip of the loco with what it is pulling and the all of that determines how.far up you will go. The elevation gain is really a function of the per turn gain needed to reach in and the radius that you can work with.
I think what your comment has highlighted, it’s just the complexity of the whole installation. I do realise there is little clearance within the levels, in fact there is only half an inch between the top of the train and the next bed, but I believe that’s enough. Regards Charlie
This video introduced me to the Powerbase. There's a section on my club's layout that has has a branchline with about 80 cm of approximately 1/25 gradient. The section is, quite obviously, notoriously bad for steam locomotives. I'll have to see about convincing them to try out the Powerbase.
Well looking good Charley. Kinda of behind I. Viewing lately lol. You could used, think I mentioned it before, cheap bathroom caulking, sticks to the track well and also sticks to metal well. Instead of screws, but end of the day what works for you is great :). I found building my first layer of the helix is always the pain and time consuming with raising the screws a little, test, lower where required test lol. But once that first run is done successfully I cut a spacer and the rest of the layers went up quick as the spacer just set it Off from my bottom layer. Fun building one though hey :)
Hi Charlie, Good to see the helix is progressing, I hope you have checked that you can get it into your railway room once complete as it looks a large construction. Regards, David.
Hi Charlie Great video as always. Its a different way than what I did when I built my first helix as I done mine from scratch myself, but anyway keep up the great videos always full of useful information Trevor
Evening Charlie. Again another great video. This tutorial on the helix is very interesting. Dave at Dean park used the DDC concepts power base on his layout 👍🏻 If you run a kettle it'll have to be banked 😆 Looking forward to seeing it back at Chadwick in situ 😄 Cheers again for your absolutely fantastic video especially with the classroom bit thrown in for good measure 🤣 You'd of made a great teacher to. Have a nice weekend and see ya until the next exciting episode on Chadwick. Cheers Stevie 😎
That is going to be one beast of a structure but should look pretty impressive once installed, think I’ll be sticking to the more simple stuff myself just a little hill with a gentle curve. Not only that, it just wouldn’t fit. As for your gluing session I know all about boring repetitive work, it’s part of my day job.
The one thing I found with the magnets is the reduced ground clearance especially with certain locos. Certainly worth checking with the screws you have used.
Another great video Charlie. I've always been curious to know what goes into preparing and building a helix, and by the looks of it, quite a lot. As you know, I'm also an advocate for the inox but I did wonder whether you might encounter adhesion issues for ascending trains. I did notice a bit of traction loss on my inclines after applying the inox. However, you might be alright with the DCC Concepts Power Base installed.
Excellent video Charlie . Love how beautifully the laser cut parts fit together. Very satisfying. For threading all those nuts on you can put a buffing wheel on your trusty Makita and hold it against the nut to spin it on quickly. Probably too late for that advice ...
If you are an obsessive, you *can* still fix the missing nut: *just* unthread the rod through the entire stack from everything below this point (or above, whichever is the shorter distance to have to shift the rod), add the missing hardware, and reverse the process. Granted, it would be tedious, but still possible. With all the other rods, getting one out and back in shouldn't be much of a structural risk.
Another great vid Charlie, Just one point though. I'd check for any reaction between the Inox and/or any glues with the flooring foam using a scrap piece of foam. I wouldn't like to see all your hard work be undone !
Charlie - love all the videos, they are most informative and entertaining. Just one small point, here in UK we use square millimeters to describe cable sizes, to save me having to convert every time can you include the square millimeter size of the wires you use.
Hi Andrew, I am also in the UK but when I buy model railway cable sizes they are metric. Such as 16 x 0.2, is 16 strands of 0.2mm cable. Regards Charlie
Another keeper video, Charlie, thank you. May use laser cut boards myself - sure is alot easier. I had to Google those steel strips under the tracks as I didn't know what they were.
Great Teamwork Gents ! Well that was a really informative video and and on a personal note, the timing of it is brilliant for me having recently got my own helix from James. Great minds think alike Charlie, because I’m also going to use PowerBase from DCC Concepts on the outside loop. I’ve also planned for a third inner loop which will be 009 gauge and reversible so will also have PowerBase. However, there the similarities between our plans end. I’m going to use DCC Concepts track underlay and, as the radius of my loops is greater than third and fourth radius, will be using flexi track (wish me luck !). Thanks James for the tip about the start of the helix rise by creating that flap in the baseboard - a very neat solution ! I was wondering how to achieve a smooth transition from baseboard to helix, now I know ! And good to learn from your lesson about Copydex Charlie, I also use it to stick track down, so may rethink that strategy where the PowerBase will be. And looks like a visit to B&Q (other DIY stores are available 🤣) to buy some more clamps ! Thanks again Gents for your joint production, you really do combine to produce an easy to understand step by step guide and your efforts are much appreciated. Take care.
Hi Charlie. Wow that'll look pretty impressive once it's finished. When I was involved with the old model railway at Sheffield Park on the Bluebell Railway which had a model of Horsted Keynes station it had a 2 turn helix at one end that was built in. There were fiddle yards top and bottom of the helix as well as a single lead junction and facing crossover so it was pretty involved in the days before DCC. I think it went up about a foot so one end was a helix and the other was a single arc that dropped down quite steeply. I do remember my old mainline Jubilee used to struggle up that so it had to be restricted to three coaches anti clockwise. Great fun to operate but it was very temperamental. I do believe it still exists but it's stored in one of the many containers around Horsted Keynes.
Hi CHARLIE Great video. Just a point on you using the screws to fix the track. Will they interfere with the magnets that you are fixing to the loco’s? I experienced a problem when I fitted the magnets with my rail fixings touching the magnets and causing a short. Hope you don’t have a similar problem. Keep the videos coming, thoroughly enjoy them.
Hi Charlie! Aren't helices just fun with all the issues they come with? Like what all could go right for once? I didn't go the route with the rods and nuts but I am thinking I probably should have. I cut 1x4's to support between each level at 3.75" since I am using .25" plywood to give a 4" rise over a 29.5" Radius. I had so many issues where both incorrect math and warping in the plywood caused me having to back step many times by having to add extra supports. It seems like you might think the first loop works great but you really can't tell until you get to loop 3 and beyond, or at least I couldn't. I am looking forward to seeing the finished project and your thoughts on it and I might consider going with rods and nuts on my 2nd one. Take care! - Jason
Hey Jason my Club used allthread and so am I. I think I told you before. I haven't been able to do much through because the weather turned bitter cold and frozen rain or snow now all week.
A technique I saw somewhere for making quick work of helix nuts was to use a power drill with a rubber wheel attachment of some kind. Probably too late though... sorry!
Hi Charlie, I can vouch for the DCC Concepts Power Base units, as I think I have said before my layout is in the garden but elevated to about waist height, 'clapped out knees again', I tried fixing the plates with PVA but it didn't like the weather so I had a trip to Screwfix and got some EvoStik Sticks like s**t, and it does, they haven't moved a fraction of an inch since. A very interesting exercise with the helix and all the various calculations needed to make sure all will be well, with the quality of the construction components I am sure it will be. Don't forget to fit the supplied magnets under your loco's as near to directly below the driving axles as possible, if you find there is rather a larger than ideal gap above the track there are brass magnet carriers available, I had to use some on my loco's, these do help to bridge the gap. Good luck with the rest of the build.
@@ChadwickModelRailway The carriers are made by DCC Concepts, they are supplied on an etched brass sheet with various sizes of offset, I think from about 4mm to about 8mm, they also do additional magnet sets to cover just about all eventualities. I think they may also supply fixing screws and a drill.
Hi Charlie! Been following you for a long time, and like many of your followers I've been struggling for many weeks with the "to build or not to build a helix" conundrum so your timing here is perfect! Fascinating explanation of the maths and other issues so I'm waiting impatiently for the next episode. But what intrigues me most is your comment that it's the track that's the most expensive element of this project. Track certainly isn't cheap but surely the helixes themselves cost more? So much fine detail work and materials involved. Maybe they cut you a special deal? ;) Anyway, keep up the great work. Cheers, Peter
Do you ever feel you’re going round in circles with this layout Charlie? (😉sorry!) These things are a major build and will be big when finished at looks of it - looking forward to seeing the end result, great video, again!
Just a thought, Charlie. As the underlay dislikes heat is it worth soldering your rail dropper wires to the track before fixing the track to the underlay? A great video and a major task on which you have embarked. Very brave :--)
Hi Charlie The only concern I have is the fact that leaving the screwed rod loose, as shown on the video with the rods obviously not vertical means that with you clamping and bonding the segments with the rods not up straight, will mean that the higher you get the further out the positioning will be and you may have to bend the rods into place thus putting under strain the existing joints that could crack/disbond them. I am no way being critical but have fallen into a similar trap myself, that was very frustrating. I must say that you are taking on on one heck of a change from what was a very simple layout initially. It will make a very interesting layout, so good luck. Also I have made some track spacers on a 3D printer that are equivalent to the red ones that Peco manufacture but are much more robust, and clip into the track holding it parallel to the adjacent track over a distance of some 75mms each. I would be happy to send you some of the if you would like them for your very extensive fiddle yards. If so how do i get hold of a postal address to get them to you. Regards Ian
Hi Ian, I do understand your thinking regarding leaving the rods loose. I have to take James' advice as this is is his bread and butter. I'm sure that it will be fine. If I need more spacers, I'll get back to you but thanks for the offer. Regards Charlie
OMG Charlie, I think I might take up golf! Excellent and informative as usual, throughout the video I kept on thinking how the hell are you going to get that back home. I’m sure you have a plan and look forward to the next instalment.
The helix looks great charlie looks more professional then something you would build in your own home and i am going to guess that the other helix that goes on the other end of the layout is the same? cheers and all the best. Nicholas.
Well impressed!! This could be a way of using all my series 3 and Super 4 curves! However, my first action point is to buy shares in the DIY store; and any company producing M8 threaded rods and nuts. I first thought you could more easily use plastic or steel sleeves on the rod, but then realised the need to make the structure rigid. And well done on not poking your eyes out on any of those rods....or is the next video from casualty😂? Should you run out of curved rails, I'm sure I have a lot spare! As always, an excellent video with lots of valuable information.
Good video. I do not understand the working of the Powerbase on the gradient. I seems like it would reduce the pulling power of the loco as it increases the drag that has to be overcome. I could understand using it to hold wagons on a gradient from running away. I will have to do some research. Did you defeat sound deadening properties you were trying to achieve by putting the Powerbase directly under the track? Would it not have been better to put it under the foam? Just curious.
@@ChadwickModelRailway I looked up all the videos I could find on the Powerbase and testing of it. Interesting idea. I am waiting to see more of your install and how it works. I might do it too.
Hi Charlie, Why have you put the DCC Concepts magnetic boosts on the downward track on the inside? Surely gravity will ensure the train has sufficient grip? It’s an obvious help to climbing a hill, but not obvious to descending one. Regards, Jim
@@ChadwickModelRailway I’m going mad Charlie! I was sure I watched you put it on both sides... it was just the gluing you were doing... magnets & track glued on the outside at the same time as track glued on the inside. There seems to be a bit of repetition going on when building these. You may be happy when you finish!
I'd like to see a helix kit with a laser cut raised track guide fixed in the six foot (~4mm mdf). So you can push flexitrack up to the guide on both sides and have neat Curves, without needing to use set track...
I was thinking that 3d printed guides would make laying the track bed and track rather precise and easy. That way flexitrack could be used with minimal issues.
@@ChadwickModelRailway I'm not sure how much track you need to swap out for it to become economical to buy a 3d printer just for this, but for those doing less popular settings, it's well worth the money.
Let this be a clear warning to anyone thinking "how hard can it be?" This hard. Excellent job!
A fair assessment MM. Regards, Charlie

@@meester5565 no as the magnets are installed under the locomotive, the track base is just steel as far as im aware

Another great video Charlie - thank you. It's looking good.
A couple of things I learnt when I built my last layout which incorporated a similar Helix with threaded rods and nuts (albeit Swiss narrow gauge single track). I deliberately incorporated some super elevation (cant) into the track sub-bed (giving me 0.8mm across the 12mm gauge track) I started with the track level, and then worked my way around to get it adjusted correctly, time consuming but straightforward (Trains (no steam locos) run perfectly with a 380mm radius curve and a 4.5% grade)
I also elongated the holes through which the rods pass to reduce the stress in the sub-bed because if you look at the vertical geometry the sub-bed is the long side (hypotenuse) of a right angle triangle. With only a 2% grade and a larger radius the difference is small but not insignificant and you may find that when complete the threaded rods are not be vertical, which of course isn't an issue if they are out of sight. Just my 2p worth but hopefully useful.
Take care and keep safe

Very interesting points John, thank you. Yes I thought of adjusting some cant on the bed which I can do towards the end of the build. Elongated holes is in a good idea and perhaps one we should look into. Regards Charlie
@@ChadwickModelRailway Sorry I forgot to mention that with my 4.5% grade I also had to use tapered wooden washers above and below the track sub-bed because when I tightened the nuts above and below they tried to flatten the sub-bed. With a 2% grade this will not be so noticeable but don't over tighten them because the clamping effect will be to flatten the sub-bed.
Great tip mate, thanks.
Charlie as much as I appreciate your prowess and professionalism in this venture , I can't share your enthusiasm I'm sorry.
I understand your point John, using a helix is not for everyone and clearly can be problematic. Regards Charlie
That is quite a piece of engineering! Very impressive.
It’s running pretty sweet too.
what a brilliant interesting upload and what a lot of work....hope your knee appreciates it!!!! great stuff.
I'm so pleased that you enjoyed it skyfall 23. Stay safe. Regards Charlie
This is an amazing project and very enjoyable to watch an explained very well. Having a double Helix opens up so many running opportunities and I guess continuous running? So there will be double track underneath the mainboard connecting the two and some sort of crossover.
Exactly Iain, but also the storage area for another 20 trains. Regards Charlie
Fascinating stuff, Charlie! I hope you’ll be able to show the helix being transported to your home and set up.
It all should be in next week’s video Perry, regards Charlie
Hi Charlie, congratulations on what, to me, appears to be a massive undertaking. In some ways it takes me back to my childhood when putting Meccano pieces together if that make sense. I will continue to follow with great interest the Helix being assembled. Again stay safe Cheers Greg
I’m so pleased I’m keeping you entertained Greg. It is a little bit of a challenge but we will get there in the end. Regards Charlie
Charlie... get a small round kitchen sponge, put a nut and bolt through the middle of it and then put the bolt in the chuck of your drill... then use it and the drill to wind down all then threaded bar bolts by using the side of the sponge to the side of the nut.. if that makes sense. Stu
Great idea Stu, I'm onto it.
Simple, very simple, but very clever. I love it. 😁👍👌
Not really worth the effort for a couple of nuts but, for a project like this, that wee idea could save 𝐚 𝐥𝐨𝐭 of time and a couple of blisters.
Great way to utilise all that normally unused space, good forethought and ingenuity.
Thanks David, that’s very kind of you to say so. Regards Charlie
Hi Charlie,
very informative and great video to show the fine details required and possible issues in helix building. Planning and thought is most definitely the key here!! Thankfully I haven't had the need to install one and not sure I would have the stomach to tackle one lol
cheers,
Derek.
Thanks Derek, it really is a drain on your time. It takes a lot more effort than I realise. Regards Charlie
Hi. very impressive and informative. You mentioned about the track being level. In real life, tracks are at an angle in curves to compensate the centripetal force of the train and helps also to keep the train not slowing down. In my curves, the first 30cm of curve track is not glued to the track bed, but then for all of the curve length ( except the last 30cm ), i elevate the outer track just 1 to 2 mm from the inner one. It works really fine.
Once I’ve got it home Josef and in place, I can the adjust the super/elevation. Regards Charlie
Nicely done, all very professional looking 👍
Thanks mate.
Thinking about building a Helix gives me a belly ache. Thanks Charlie. Cheers 🍻 from the good old, but a little off USA.
You know that you really want one Patrick, go on, build it
Hi Charlie..... All looks to be coming together just fine. All the research.parameters etc spot on and explained well. Something worth considering
when finished is to make up a control train.... loco plus a load of rolling stock that can just make it up the helix without wheel slip. Keep this
train as a unit train or take note of it's makeup, throttle setting etc maybe also. First run: Track must be 'virgin' ... clean as possible and shinny. (Track could be washed in your sink maybe as you assemble helix's. [G} ). Reason I pass this on is as you use the up helix performance will change depending on how you clean the track or run your trains. The control train gives you a base to compare performance against later on. You may get a few surprises depending on how you treat your track.
A very interesting point Indigo. Many thanks, regards Charlie
Looks awesome Charlie....can’t wait to see it in situ.
Thanks Ron,
I’m so pleased that you found the video interesting. Regards Charlie
Hi Charlie another great video mate great information on binding your helixs I really injoyed it so much I am looking forward to see them on your layout and seeing trains runing on them it will be every interested keep up the great work mate stay safe and well mate goodbye for now Clive
Thanks Clive. Another heartwarming comment mate. Regards Charlie
Very nicely done. I love it. My question is if the rise of each round is the same why done we cut a piece of pipe of the high and place it in the rode under each board so turnings the nuts height would be easier.
That’s a fair point SM but should you change your mind a need a less steep rise, you would be snookered.
That's certainly a major project which requires plenty of skill. My layout wouldn't benefit from a helix and if it did I wouldn't attempt to build one. It's about knowing your limits and for me it's certainly off limits. Hats off to you and a very interesting watch
I’m so pleased that you found it interesting ER.
Wow a lot of (to me) complicated calculations amazing job Charlie can’t wait to see it in place on the layout
You and me both David.
Excellent film. Thank you.
I’m so pleased that you enjoyed it Ian.
Fully makes sense on your mathematics, I wish I had seen a video like this before I built mine. Great detail and reasons why you are using Power Base (magnets) on up track, looking forward to seeing helix in place..
Thanks Barry, I’m so pleased that you enjoyed the video. Regards Charlie
Charlie what an informative and educational video, Top Bloke..
Thanks Colin, you’re too kind, regards Charlie
I have long fantasized running a train around the house above the window frames, bringing it down wherever it was convenient. a Helix would get the train up there!
It must be about time you built it Jerry. Regards Charlie
What a great piece of engineering! Thanks for sharing the experience!
I’m so pleased that you found it interesting, regards Charlie
Great update Charlie
Thanks Matthew I’m so pleased that you found it interesting. Regards Charlie
Nice video. Great to see such a full treatment.
When watching the spreadsheet work at 9:00 as you cranked up the revolutions to cover the 18 inches to get the grade down, I became worried as you were not watching the elevation gain per revolution. It’s all nice on paper but in that One revolution you have to get the loco and cars in there by height so the roof doesn’t hit the bottom of the next revolution.
3.27 inches is what you computer. That’s going to be a very tight squeeze for OO locos. Not running electrics the pantograph issue doesn’t come into play. But you still will want the space to be such that you can get your hand in there to address an issue if needed between the levels.
So my recommendation to folks is to build it to the lowest height that will work for your locos (tallest loco with pantos up if your need that) and still allow your fingers over the loco so you can pick it up and place it back. That sets the minimum gap per revolution.
The room then likely sets the radius of the circle, of the grip of the loco with what it is pulling and the all of that determines how.far up you will go.
The elevation gain is really a function of the per turn gain needed to reach in and the radius that you can work with.
I think what your comment has highlighted, it’s just the complexity of the whole installation. I do realise there is little clearance within the levels, in fact there is only half an inch between the top of the train and the next bed, but I believe that’s enough. Regards Charlie
This video introduced me to the Powerbase. There's a section on my club's layout that has has a branchline with about 80 cm of approximately 1/25 gradient. The section is, quite obviously, notoriously bad for steam locomotives. I'll have to see about convincing them to try out the Powerbase.
Do make sure that your steamers have space for the magnets mate.
Some work that is, Charlie! Brilliant channel, love every episode of it!
You’re too kind GL. Regards Charlie
Well looking good Charley. Kinda of behind I. Viewing lately lol. You could used, think I mentioned it before, cheap bathroom caulking, sticks to the track well and also sticks to metal well. Instead of screws, but end of the day what works for you is great :).
I found building my first layer of the helix is always the pain and time consuming with raising the screws a little, test, lower where required test lol. But once that first run is done successfully I cut a spacer and the rest of the layers went up quick as the spacer just set it Off from my bottom layer. Fun building one though hey :)
It certainly was an interesting challenge Sean. Regards Charlie
Fascinating and very engaging episode! The mind bogles how you get the thing back to your train room...thanks
That’s in the next episode!
Hi Charlie, Good to see the helix is progressing, I hope you have checked that you can get it into your railway room once complete as it looks a large construction. Regards, David.
That’s the next video David.
Hi Charlie
Great video as always.
Its a different way than what I did when I built my first helix as I done mine from scratch myself, but anyway keep up the great videos always full of useful information
Trevor
I’m so pleased that you enjoyed it Trevor, regards Charlie
I have also used DCC Concepts Powerbase and it worked very well for me.
That is good news, it was just a struggle to get it to stick down. Regards Charlie
@@ChadwickModelRailway I used UHU glue, seemed to work a treat :D
Great tip, thanks
Evening Charlie. Again another great video. This tutorial on the helix is very interesting. Dave at Dean park used the DDC concepts power base on his layout 👍🏻 If you run a kettle it'll have to be banked 😆 Looking forward to seeing it back at Chadwick in situ 😄 Cheers again for your absolutely fantastic video especially with the classroom bit thrown in for good measure 🤣 You'd of made a great teacher to. Have a nice weekend and see ya until the next exciting episode on Chadwick. Cheers Stevie 😎
Thanks Stevie, what a delightful comment. In fact it’s comments such as yours that make the whole UA-cam thing worthwhile. Regards Charlie
That is going to be one beast of a structure but should look pretty impressive once installed, think I’ll be sticking to the more simple stuff myself just a little hill with a gentle curve. Not only that, it just wouldn’t fit. As for your gluing session I know all about boring repetitive work, it’s part of my day job.
I’m so pleased that you found it interesting Rob, regards Charlie
The one thing I found with the magnets is the reduced ground clearance especially with certain locos. Certainly worth checking with the screws you have used.
Excellent point Richard.
Hey Charlie,loved when you where working in both metric & imperial.........I do exactly the same.......keep up the great work.atb
I’m so pleased that you enjoyed it Sid.
That is a lot of precise work Charlie, feels like a lots of pennies, incredible video. can't wait to see it in situ, good luck.
I’m so pleased that you found it interesting Bob. I too, am excited about its installation. Regards Charlie
Nice one on doing the new project on layout keep posting updates up
I certainly will AR
Another great video Charlie. I've always been curious to know what goes into preparing and building a helix, and by the looks of it, quite a lot. As you know, I'm also an advocate for the inox but I did wonder whether you might encounter adhesion issues for ascending trains. I did notice a bit of traction loss on my inclines after applying the inox. However, you might be alright with the DCC Concepts Power Base installed.
I'm so pleased that you enjoyed it Station Road Model Railway.
The Inox point occurred to me too but only time will tell.
Stay safe. Regards Charlie
Excellent video Charlie . Love how beautifully the laser cut parts fit together. Very satisfying. For threading all those nuts on you can put a buffing wheel on your trusty Makita and hold it against the nut to spin it on quickly. Probably too late for that advice ...
Yes it is a little late Peter for that advice. However I have of course another Helix to build! Regards Charlie
If you are an obsessive, you *can* still fix the missing nut: *just* unthread the rod through the entire stack from everything below this point (or above, whichever is the shorter distance to have to shift the rod), add the missing hardware, and reverse the process. Granted, it would be tedious, but still possible. With all the other rods, getting one out and back in shouldn't be much of a structural risk.
Thanks O50, I’m pleased that you understand my situation.
Regards Charlie
Another great vid Charlie, Just one point though. I'd check for any reaction between the Inox and/or any glues with the flooring foam using a scrap piece of foam. I wouldn't like to see all your hard work be undone !
A good point PP. I shall certainly check it out, regards Charlie
Your first helix is really coming along there Charlie.
I'm still doing the math on mine, more so on the where it starts to where it ends.
Yes, can be a little bit challenging trying to figure it out. Regards Charlie
Charlie - love all the videos, they are most informative and entertaining. Just one small point, here in UK we use square millimeters to describe cable sizes, to save me having to convert every time can you include the square millimeter size of the wires you use.
Hi Andrew, I am also in the UK but when I buy model railway cable sizes they are metric. Such as 16 x 0.2, is 16 strands of 0.2mm cable. Regards Charlie
Hey Charlie , that looks incredible 👍👍
Thanks mate, regards charlie
Another keeper video, Charlie, thank you. May use laser cut boards myself - sure is alot easier. I had to Google those steel strips under the tracks as I didn't know what they were.
Thanks Terrence, I’m so pleased that you enjoyed it
Great Teamwork Gents ! Well that was a really informative video and and on a personal note, the timing of it is brilliant for me having recently got my own helix from James. Great minds think alike Charlie, because I’m also going to use PowerBase from DCC Concepts on the outside loop. I’ve also planned for a third inner loop which will be 009 gauge and reversible so will also have PowerBase. However, there the similarities between our plans end. I’m going to use DCC Concepts track underlay and, as the radius of my loops is greater than third and fourth radius, will be using flexi track (wish me luck !). Thanks James for the tip about the start of the helix rise by creating that flap in the baseboard - a very neat solution ! I was wondering how to achieve a smooth transition from baseboard to helix, now I know ! And good to learn from your lesson about Copydex Charlie, I also use it to stick track down, so may rethink that strategy where the PowerBase will be. And looks like a visit to B&Q (other DIY stores are available 🤣) to buy some more clamps ! Thanks again Gents for your joint production, you really do combine to produce an easy to understand step by step guide and your efforts are much appreciated. Take care.
What an excellent comment Bryan. Good luck with your Helix In do keep in contact should you have any problems. Regards Charlie
Hi Charlie. Wow that'll look pretty impressive once it's finished. When I was involved with the old model railway at Sheffield Park on the Bluebell Railway which had a model of Horsted Keynes station it had a 2 turn helix at one end that was built in. There were fiddle yards top and bottom of the helix as well as a single lead junction and facing crossover so it was pretty involved in the days before DCC. I think it went up about a foot so one end was a helix and the other was a single arc that dropped down quite steeply. I do remember my old mainline Jubilee used to struggle up that so it had to be restricted to three coaches anti clockwise. Great fun to operate but it was very temperamental. I do believe it still exists but it's stored in one of the many containers around Horsted Keynes.
I'm so pleased that you enjoyed it DJ. Stay safe. Regards Charlie
As usual a superb show! Thanks mate👍🏻
You’re too kind Mark.
Hi CHARLIE
Great video. Just a point on you using the screws to fix the track. Will they interfere with the magnets that you are fixing to the loco’s? I experienced a problem when I fitted the magnets with my rail fixings touching the magnets and causing a short. Hope you don’t have a similar problem. Keep the videos coming, thoroughly enjoy them.
Hi John, they wont touch but they might have an adverse effect on the loco's movement!
Great video, Charlie!!
Thanks Dave, regards Charlie
Hi Charlie! Aren't helices just fun with all the issues they come with? Like what all could go right for once? I didn't go the route with the rods and nuts but I am thinking I probably should have. I cut 1x4's to support between each level at 3.75" since I am using .25" plywood to give a 4" rise over a 29.5" Radius. I had so many issues where both incorrect math and warping in the plywood caused me having to back step many times by having to add extra supports. It seems like you might think the first loop works great but you really can't tell until you get to loop 3 and beyond, or at least I couldn't. I am looking forward to seeing the finished project and your thoughts on it and I might consider going with rods and nuts on my 2nd one. Take care! - Jason
A brilliant and honest comment Jason. And one which I really appreciate, fingers crossed, I know it’s a challenge. Regards Charlie
Hey Jason my Club used allthread and so am I. I think I told you before. I haven't been able to do much through because the weather turned bitter cold and frozen rain or snow now all week.
Well Charlie, you have got my admiration for tackling this awesome project. I cannot wait to see the next installment.
Thanks Philip, I’ll certainly keep you posted, regards Charlie
A technique I saw somewhere for making quick work of helix nuts was to use a power drill with a rubber wheel attachment of some kind. Probably too late though... sorry!
Not too late at all Nick. I’ve got another one to build yet!
Great stuff again Charlie. Your video's are superb
Thanks Robin, you’re too kind.
Hi Charlie, I can vouch for the DCC Concepts Power Base units, as I think I have said before my layout is in the garden but elevated to about waist height, 'clapped out knees again', I tried fixing the plates with PVA but it didn't like the weather so I had a trip to Screwfix and got some EvoStik Sticks like s**t, and it does, they haven't moved a fraction of an inch since.
A very interesting exercise with the helix and all the various calculations needed to make sure all will be well, with the quality of the construction components I am sure it will be.
Don't forget to fit the supplied magnets under your loco's as near to directly below the driving axles as possible, if you find there is rather a larger than ideal gap above the track there are brass magnet carriers available, I had to use some on my loco's, these do help to bridge the gap.
Good luck with the rest of the build.
I’m interesting, Peter. Can you tell me who makes these brass carriers? Regards Charlie
@@ChadwickModelRailway The carriers are made by DCC Concepts, they are supplied on an etched brass sheet with various sizes of offset, I think from about 4mm to about 8mm, they also do additional magnet sets to cover just about all eventualities. I think they may also supply fixing screws and a drill.
Hi Charlie! Been following you for a long time, and like many of your followers I've been struggling for many weeks with the "to build or not to build a helix" conundrum so your timing here is perfect! Fascinating explanation of the maths and other issues so I'm waiting impatiently for the next episode.
But what intrigues me most is your comment that it's the track that's the most expensive element of this project. Track certainly isn't cheap but surely the helixes themselves cost more? So much fine detail work and materials involved. Maybe they cut you a special deal? ;)
Anyway, keep up the great work.
Cheers,
Peter
I think that you will be quietly surprised Peter once you’ve worked out the cost of the track. Regards Charlie
Do you ever feel you’re going round in circles with this layout Charlie? (😉sorry!) These things are a major build and will be big when finished at looks of it - looking forward to seeing the end result, great video, again!
I'm so pleased that you enjoyed it ZappaTime. Stay safe. Regards Charlie
Just a thought, Charlie. As the underlay dislikes heat is it worth soldering your rail dropper wires to the track before fixing the track to the underlay? A great video and a major task on which you have embarked. Very brave :--)
Hi Pat, I couldn’t have explained it very well. Yes I have soldered all the dropper cables on prior to fitting. Regards Charlie
Hi Charlie
The only concern I have is the fact that leaving the screwed rod loose, as shown on the video with the rods obviously not vertical means that with you clamping and bonding the segments with the rods not up straight, will mean that the higher you get the further out the positioning will be and you may have to bend the rods into place thus putting under strain the existing joints that could crack/disbond them. I am no way being critical but have fallen into a similar trap myself, that was very frustrating. I must say that you are taking on on one heck of a change from what was a very simple layout initially. It will make a very interesting layout, so good luck. Also I have made some track spacers on a 3D printer that are equivalent to the red ones that Peco manufacture but are much more robust, and clip into the track holding it parallel to the adjacent track over a distance of some 75mms each. I would be happy to send you some of the if you would like them for your very extensive fiddle yards. If so how do i get hold of a postal address to get them to you.
Regards
Ian
Hi Ian, I do understand your thinking regarding leaving the rods loose. I have to take James' advice as this is is his bread and butter. I'm sure that it will be fine. If I need more spacers, I'll get back to you but thanks for the offer. Regards Charlie
OMG Charlie, I think I might take up golf! Excellent and informative as usual, throughout the video I kept on thinking how the hell are you going to get that back home. I’m sure you have a plan and look forward to the next instalment.
I’m so pleased that you enjoyed it Kevin.
Stay tuned for transportation!
The helix looks great charlie looks more professional then something you would build in your own home and i am going to guess that the other helix that goes on the other end of the layout is the same? cheers and all the best.
Nicholas.
Yes Nicholas, that is the current plan. Regards Charlie
Well impressed!! This could be a way of using all my series 3 and Super 4 curves! However, my first action point is to buy shares in the DIY store; and any company producing M8 threaded rods and nuts. I first thought you could more easily use plastic or steel sleeves on the rod, but then realised the need to make the structure rigid.
And well done on not poking your eyes out on any of those rods....or is the next video from casualty😂? Should you run out of curved rails, I'm sure I have a lot spare!
As always, an excellent video with lots of valuable information.
What a cracking comment in Ian. It’s great to have you onboard and so enthusiastic with the videos that I produce. Take care buddy, regards Charlie
Good video. I do not understand the working of the Powerbase on the gradient. I seems like it would reduce the pulling power of the loco as it increases the drag that has to be overcome. I could understand using it to hold wagons on a gradient from running away. I will have to do some research. Did you defeat sound deadening properties you were trying to achieve by putting the Powerbase directly under the track? Would it not have been better to put it under the foam? Just curious.
Interesting points mate. With the power base, you need to fit small magnets underneath your locos to enhance their grip. Regards Charlie
@@ChadwickModelRailway I looked up all the videos I could find on the Powerbase and testing of it. Interesting idea. I am waiting to see more of your install and how it works. I might do it too.
Hi Charlie,
Why have you put the DCC Concepts magnetic boosts on the downward track on the inside? Surely gravity will ensure the train has sufficient grip? It’s an obvious help to climbing a hill, but not obvious to descending one.
Regards,
Jim
Sorry Jim but it is only on the outside track. Regards Charlie
@@ChadwickModelRailway I’m going mad Charlie! I was sure I watched you put it on both sides... it was just the gluing you were doing... magnets & track glued on the outside at the same time as track glued on the inside.
There seems to be a bit of repetition going on when building these. You may be happy when you finish!
I'd like to see a helix kit with a laser cut raised track guide fixed in the six foot (~4mm mdf). So you can push flexitrack up to the guide on both sides and have neat Curves, without needing to use set track...
I was thinking that 3d printed guides would make laying the track bed and track rather precise and easy. That way flexitrack could be used with minimal issues.
Certainly interesting points gentlemen. And of course the Flexi track will be so much cheaper. Regards Charlie
@@ChadwickModelRailway I'm not sure how much track you need to swap out for it to become economical to buy a 3d printer just for this, but for those doing less popular settings, it's well worth the money.
A band saw and a radius cutting jig. Or a radius jig and a router.
Are you able to glue the overlayment to the boards before cutting? Might save some menial labor in the long run.
An interesting thought Sam, and I shall check it out.
Morning Charlie,
Looks good but a Steady job eh, look forward to seeing it in action,
Now awaiting transportation Mick.
