Hi Paul! I have been super busy for the last couple of months because of moving to the new place and now I am catching up all videos I had no time to watch, however, I was visiting your Facebook profile as well as UA-cam channel systematically to check how you were feeling and today I just want to tell you that I'm really glad I can see you smiling and working on the new projects!!! PS. Mitch, congrats on your trip to Mongolia! Hopefully we can see a short (or long!) video from there. This short trailer at the beggining of the vide is amazing. All the best Guys! Matthew
Thank you, as always, Paul & Mitch. @Mitch -- my wife & I lived in Mongolia for a year in 2002-3. One of the best things I've ever done. I'd love to go back, and your Royal Enfield approach seems awesome!
Congratulations on your "People's Choice" Award! I bet there was a lot of jaws dropping and finger pointing. It takes more heart than pride to be as good as you. Really makes my weekend. Thanks.
Was under the misconception for all these years that bicycles were the simplest of machines. Paul showing that there are certainly differences in construction and we are seeing the equivalent of a Rolls Royce being built. Excellent and completely absorbing with the quality of camera work you don't miss the slightest detail.
I would watch you doing this all day if I had the chance. You make those full-sized drawings, which absolutely make sense - -but then you are still able to extrapolate the top-view beside the side view. Things I'd never thought of till now. Cheers Rick from New Zealand
It reminds me a lot of my first motorcycle frame build I drew it all up in CAD thinking i was so clever but when it was time to bring it to the physical world.. wow, i used all 12 feet of my workbench as a drawing table! I scribe my bend marks, used v blocks for holding my tubes and making sure everything was going acording to plan. Thank you for sharing you're experience Paul.
Very well explained & very well documented, thanks Paul for going over the finer details only a master would know & thanks Mitch for getting right in there & giving us the angles to see exactly what's going on.
Thanks for giving us a glimpse into your hand built frames, Paul. It really gives me an even greater appreciation of the skills and talents that you possess. My formative years in mountain bikes was the mid 90's to early 2000s, when frames and components were still hand fabricated and welded. Mountain bike companies were still fairly "boutique". I still have my 1998 Rocky Mountain Element (welded in Vancouver), fit out with Syncros and Race Face components (when they were still small, Vancouver based companies). I'm sure that most of that stuff has some of your DNA in it.
Paul, that's an absolutely beautiful solution to the brake mounting on the fork, really elegant, so much different than your first try - amazing what a few weeks to let the brain churn can do. Looks like you'll have enough CS length and width to run some 700x40C if you wanted something more "road". PS, as someone who naturally lacks hair, happy to see your hair returning so vigorously 😀
Thanks. It wasn't a few weeks; it was the very next day! I can't run 700 X 40, I have 650b X 50. And yes, my hair is coming back pretty thick and very curly!
So gooood every time gets better. Paul what’s the difference between fillet or TIG welding in the frame behavior? For an amateur builder which does make more sense to learn? Thanks! Fede
Love these video’s. I’ve been rebuilding upgrading bicycles for the last 5 years to try to keep my son on the trails. Never fully understood the geometry.
*_You make it look easy. Was thinking, I wonder what a bike would look like if you and Indian Larry were to team up and make a show bike._* 😆🤣💯💘🚴♀🚴♂🚴
Thanks for making this Paul! You've definitely done this enough to figure out all the nuances of making a bike, and I love your simple fixtures and seeing your use of paper and pencil. One thing I expected but didn't see is a consideration of crank arm and chainring clearances. Especially on shorter chainstay bikes that area can get pretty tight. Though I suppose that since most bikes are single front rings these days, maybe it's not a big deal?
These are fantastic videos! Thank you so much for walking us through the steps. Can you do a video about geometry of a bike and how it affects the feel and ride characteristics?
Hey Paul, I was under the impression that it would be best to drill the hole at the end of the seat tube slot before cutting the slot itself. Why do you cut the slot first?
If you drill the hole first, and then try to line up the cutter with the hole, and do not correctly line it up, then that is a problem. Maybe some frame builders do it that way, but I do not...
Hey Paul, could not help but notice the red e-bike in the background. I see there is a multitude of cable ties holding it on. You are meant to use just three of the holes each side to fix it to the frame. The others are a backup, in case some of the cable ties rip out in the event of a crash. Or at least that's why the manufacturer put all those holes there ;)
I looked at the red bike, and the cables go into the frame on each side. There is only one hole on each side. It is stock. I do not know how you are seeing 3 holes each side...
@@paulbrodie Sorry, I forgot to mention that I am referring to the rear fender. You are only meant to use three holes out of the six per side to attach it to the seatstays.
I’m starting to really like those little v12 model engine kits. If I were to do one up, like make it strong enough to do useful work, would that make a cool board track racer? Will they all laugh at me?
Appreciate the Sharpie because pencil lines do not come across on a phone screen. Glad to see how well you've recovered. Also haven't heard your Peacock making noise this year, is he okay?
I'm as much impressed with your hair as your building skills. You had it nuked right off your head with chemo, and it still comes back 5x thicker than mine. Excellent! (Oh well, at least my head is more aerodynamic than yours. Hey, I gotta find some bright side to cling to here...) 😜
I have a steel frame that mirrors your tubing diameters and building choices/solutions - so even the same ovalizations and miters. This series gives invaluable understanding of the whole design and construction process. My question, if this is the right place to ask, why is the down tube joined to the bb first. Across decades in shops I've seen failed frames where the seat tube separated or cracked on both welded and lugged frames. A late 80s FEA revealed the seat tube to bb is one of the most strained locations. My thinking make that joint the most solid with the down tube as a less critical connection. Can you illuminate?
Really enjoying this build, it's looking sweet so far, great video as always Paul thank you for uploading! 👍👍 What's the story with that blue frame in the bike stand in the beginning of the video? That's really cool looking, don't think I've ever seen a bike like that before. Would be cool to get some info on it. 👍
Was that Mitch the Mighty One in the red robe at the start ?? 0:31 , Mind you Royal Enfield is a very unusual name for a horse ,, lol Great video , I have never looked at frames so closely before , a very interesting process .
@@mitchellnurseproductions never let the truth stand in the way of a good story ... you would have got away with being the man on the horse LOL.. great job your doing and nice to see the dream team reunited.
Hi Paul, any reason that you went with the Syntace dropouts? Did you just try and make the mating surfaces of the dropout level? Or is there a specific rotation angle for them to work?
Why do you TIG tack then Braze? As opposed to TIG the whole joint without a fillet braze. (I understand the Tack is to aid holding while Brazing, my question is why is a Braze preferred over a soil weld.) Is this for Looks, Strength, Fatigue or distortion? Just wondering..... Thanks for the great content and tor Mitch, riding a Motorcycle in Mongolia is one of my dreams. Well done.
@@paulbrodieI'm thinking like a hobbyist. No need to invest in brazing equipment and still be able to have the versatility and cleanliness of tig with less heat deformation than the TIG welding.
Someone needs to invent a deburring tool for the outside of tubes. I have a cone shaped abrasive thing at work that does both ID and OD of tubes but it wears a groove into it and makes it useless almost immediately, and leaves a pink grinding dust on everything. If I figure out a concept I'll be happy to share it with anyone who would want to try it.
Thank you very much for another great video! I’m curious: why do you cut the seat tube slot first and then drill the stress relieving hole after? I have seen other framebuilding videos where the builder drills the hole first and then cuts the slot to meet the hole. While the second way looks easier, I suspect the #fussyframebuilder has a reason for doing it the way he does :)
Your builds seem to be 100% mechanical skill plus 10% magic.
And thanks to Mitch for sharing a glimpse of his trip.
Glad you enjoyed it, and thanks for watching!
Paul is looking so much better, really happy about that!
Great job as always!
Yes! Thank you!
I was going to say the exact same thing. Happy for him.
This is going to be hell of a beautiful gravel bike, and hell of a tutorial for framebuilders! Thank you Paul & Mitch!
Glad you like it! And thanks for watching...
Love this competency and presentation style.

All the best Guys!

Thanks Matthew. We appreciate your comments!!
You build frames like how our traditional wooden boatbuilders do in Terengganu, Malaysia. Everything has to be 'Eye Sweet" !!! Amazing Paul!
Thank you, as always, Paul & Mitch. @Mitch -- my wife & I lived in Mongolia for a year in 2002-3. One of the best things I've ever done. I'd love to go back, and your Royal Enfield approach seems awesome!
It’s one of the most beautiful places I’ve ever been. A month wasn’t enough, a year must have been amazing!
The blue bike behind you Paul is looking fantastic. I would love to see it complete!
I am working on it for an upcoming show. Thanks..
Glad you mentioned it, as I was watching the video thinking, "what's the story with that blue bike in the background?"
Congratulations on your "People's Choice" Award!
I bet there was a lot of jaws dropping and finger pointing.

Paul showing that there are certainly differences in construction and we are seeing the equivalent of a Rolls Royce being built. Excellent and completely absorbing with the quality of camera work you don't miss the slightest detail.
Bicycles are simple only because thousands of people have iterated and found experimentally functional solutions 😅
Thank you very much. Yes, bicycle construction really can be quite sophisticated!
I would watch you doing this all day if I had the chance.
You make those full-sized drawings, which absolutely make sense - -but then you are still able to extrapolate the top-view beside the side view. Things I'd never thought of till now.

Old school paper drafting
It reminds me a lot of my first motorcycle frame build
I drew it all up in CAD thinking i was so clever but when it was time to bring it to the physical world.. wow, i used all 12 feet of my workbench as a drawing table! I scribe my bend marks, used v blocks for holding my tubes and making sure everything was going acording to plan.
Thank you for sharing you're experience Paul.
Really like the giant drawing and the way it allows you to place each section onto it checking dimensions as you go, so clever Mr. Brodie!
Hoesit Paul .
It does not matter what your current project is, you are a pleasure to watch .
Thank you so much for the great blog .
6:30 frame sounds surprisingly melodious and melancholic.
Very well explained & very well documented, thanks Paul for going over the finer details only a master would know & thanks Mitch for getting right in there & giving us the angles to see exactly what's going on.

Thanks Mark. We all contributed a bit to the Vancouver Handbuilt scene which did spread across the world...
Beautiful Alignment Paul, WOW!
I like your hair Paul. All the best from Australia.
Superb 👌👌looking good Paul
Cheers Chris
Thanks 👍 Hope you are well, Chris...
You look great Paul. I told you always think positive. Stay healthy. And I love the videos
Kevin, thank you very much!
Hats off! And I thought that I had a good geometric imagination.
Thank you, I think :)

You both do perfect job!
Thank you. We are a good team :)
Well done!

Can’t wait to see how you machine the basket for the front.
Looking great Paul - ever think of making a curly hetchens replica?
Amazing as always. Thank you Paul ! Cheers from Nova Scotia !!
Thank you :)
you're the man Paul!
Nice comment, thank you!
Thank you very much for sharing your knowledge!
Glad it was helpful! And thanks for watching..
Front brake mount is much nicer than the angled plate, 'elegant' is probably best description?
Cool to see how much 'precision guesswork' is involved
For filets, I like a rolock disk at 240 grit at about 1500 rpm. It’s much more dexterous than anything else. I do aircraft metalwork out in Malden.
Love these video’s. I’ve been rebuilding upgrading bicycles for the last 5 years to try to keep my son on the trails. Never fully understood the geometry.
Thank you. To understand geometry Google "Trail" and see what comes up. It is a function of head tube angle, fork offset, and tire diameter...
*_You make it look easy. Was thinking, I wonder what a bike would look like if you and Indian Larry were to team up and make a show bike._* 😆🤣💯💘🚴♀🚴♂🚴
Check the "concours des machines" in France, every year - you'll see talented framebuilders who'll give you an idea of that :)
@@nicojar Interesting but not quite what I was thinking.
Indian Larry had been dead for close to 20 years now. en.wikipedia.org/wiki/Indian_Larry
@@GreggMax DERP! DOINK! OYEE!!!! Ya don't say! Very observant MORE-ON!
Hy Paul! Tomorrow morning I will be at Pegoretti to build my new steel frame!

Cracking series Paul. Thanks heaps!
Love the blend of classic engineering and eyeball art, guess that's the beauty of most of what you do!
awesome video, looking forward to seeing this fine machine
fully equipped and `off` road tested, nice camra work there mitch,
thanks dynamic duo, 😊👍
Paul, it's like you know what your doing 😂...... Stunning work 👍👍 Any chance Mitch will be sharing more of his Mongolian adventure?
I will be putting together a short video of my Mongolian adventure. Not sure when but I'll probably add it to my (small!) channel.
Loving this series👍🏻
Masterclass!
I spent the last month riding around Indiana on a Royal Enfield.....Yeah, Mitch's trip sounds far more interesting than mine. lol
It was definitely interesting!

Off topic - but will Mitch be releasing any footage from his Mongolian adventure? Your frame building process is true art.
I will be putting together a short video of my Mongolian travels and releasing it on my channel. Thanks for your interest!
Quality.
Wow!
Très instructif, merci beaucoup ! Si un jour les sous titres sont disponible en français, cela serait formidable :)

Appreciate the Sharpie because pencil lines do not come across on a phone screen. Glad to see how well you've recovered. Also haven't heard your Peacock making noise this year, is he okay?
What about that blue bike in the background in the beginning. Tell me you aren’t gonna Easter egg us!!! That looked gorgeous
That's my touring bike I built in 2013, I think. I'm getting it ready for a show.
The construction is just exquisite and sophisticated. Question though, are frames supposed to be stress tested before handing it to the customer?
Thank you. We always let the customer do the stress testing. They seem to enjoy that :)
I'm as much impressed with your hair as your building skills. You had it nuked right off your head with chemo, and it still comes back 5x thicker than mine. Excellent! (Oh well, at least my head is more aerodynamic than yours. Hey, I gotta find some bright side to cling to here...) 😜

Thank you. Yes, chainring clearance is often as issue with 68 or sometimes 73mm bottom brackets. Not usually with 83mm BB's, but I will check...

Would mass produced bikes be built in simular way.?
Sorry Paul but that d/t to h/t joint looks like a repair ! Why did you not raise the d/t up a little ? Amazing work though !
A repair, eh? Thanks. Raising the D/T looks like crap IMO.
