Documenting a few of the interesting things I do or have discovered while working in my shed
Aircraft engine parts
I was asked if I could make up some model aircraft engine parts for some old engines a work colleague had. Interesting little project but did require some thinking about how to hold things.

Clamping sheet corners for welding
Переглядів 1,6 тис.21 годину тому
A few weeks ago I 'interpreted' some butt clamps that @ThisOldTony made. This week I'm inventing my own sort of clamp for holding corners while tacking (If anyone knows of these commercially, please say so in the comments)
Fabricating with conical sections

Bit of a rush job, but I was asked if I could make up some mudguards for an off-road chair. I could have shaped them (hammer and dolly) from flat, but making from sheet saved a bit of time and effort on my part. I mentioned some tooling I used for securing parts while tacking at around 10:30, but mixed up the brand. The correct brand is @stronghandtools (not a sponsor). Worth considering if you...
Basic geometric operations for marking out

Sorry - no machining in this one. I'm still not 100%, so instead this video is about some of the basic geometry (Probably no longer taught in schools) that can help mark out work
Butt clamp challenge
Переглядів 2,4 тис.28 днів тому
I was watching @ThisOldTony recently where he made up some butt clamps (ua-cam.com/video/vK8CmznlbeU/v-deo.html), and one of my reactions was "I could make some of them, but mine would look more like...", so in the spirit of youtubing, I did. I'm sure TOT would have challenged the whole tuberverse to a build off if he had had time, so this is me doing my part. Apologies if I sound a little croa...
Squaring up with a cylinder

In this video I make up a cylindrical square. Although properly made on a cylindrical grinder, something basic and serviceable can be made on a lathe that will at least help with checking the squares you have.
Have I made it worse?

Last week I started working on a gauge to help me measure bores. The first version works, but I thought I might be able to improve on that first version. I've remade several parts to make it more rigid, but that seems to have stiffened up the joints. Looks like more work required...
Sideways gauge

I have an Interapid IRA 2A which I really like. The only thing I don't like is the amount of headroom it takes up. In this video, I start on a design that I've been thinking about for 4 or 5 years that should get around this.
The grabber returns

Last video I cut the gears for the rack and fingers. In this video, I get the rest of the arm together so I can try things out. The thumbnail is the haul I managed at the lake. Not as much as I feared but more than should be there (that's a 20 litre bucket). As suspected, I need to beef up the spring, and the handle is not as stiff as it needs to be, but all in all, a successful trial.
A gripper with purpose
Переглядів 5962 місяці тому
There is an artificial lake near work and I've noticed a collection of plastic wrappers and other rubbish in it. After thinking "someone should do something about that", I realised that I was a someone and decided to start doing something about it, so I've started making a 2m long arm with gripper that can reach some of this litter and get it out and in the bin. I mention a @ThisOldTony episode...

Today I do a little more on the vice, this time finish off the base and maching and mount the fixed jaw. As mentioned in the previous video, the vice (vise) is a copy of one designed and made by Rudy Kouhoupt, published in Home Shop Machinist Vol 10, No. 6 Nov/ Dec 1991. For such a simple design, it's an interesting build and I'm hoping to use it on my surface grinder, as well as in other ways ...
Boot strapping a mill part 4

One of the things I have been promising is a vice as part of this series. In this video I start on it. The vice (vise) is a copy of one designed and made by Rudy Kouhoupt, published in Home Shop Machinist Vol 10, No. 6 Nov/ Dec 1991. In that article Rudy gives dimensions and methods. I'm putting a little bit of metric in and doing things my way, but that's the basis of it.
Boot strapping a mill - a slight detour
Переглядів 1,9 тис.3 місяці тому
I have been showing how to make up cheap tooling to get you started with milling, but it all supposes you can hold the cutter. In this clip I make up a collet chuck on the lathe (no mill needed); although you would still need to buy collets (and potentially a nut and spanner), it does show the method if you need to make up a special or want to make a custom collet chuck. This one is ER25 to MT3...

Connector cutouts and a quicker way of making them

Connector cutouts and a quicker way of making them
As soon as you mentioned needing to manufacture aircraft parts, I remembered a similar situation ~35 years ago. A coworker was building a kit airplane (person-size) in his garage and had an "oops!" while attempting to make a high-speed taxiing test at a local airfield. It took off at a much lower speed than he had expected and by the time he got it back down onto the ground, he was out of room near the end of the runway. The only thing physically damaged by his hard landing was a piece of landing gear (LDG) linkage that snapped due to the loading. He brought the broken into work and was standing near me when he showed it to another coworker. I overheard them discussing it and told him that I had a mill-drill in my garage and would be willing to machine a replacement for him. He gave me the two pieces of the LDG plus a piece of aircraft-quality 7075 (or very similar type) aluminum -- I machined it at home and brought it back to him after the next weekend. He was quite relieved to have his (I think it fell into the category of ) "experimental" home-built aircraft back in business so that he wouldn't have to delay his next mandatory inspection in order to get the airplane certified for flight. However, I've never tried to machine anything like the delicate model aircraft engine components that you built for your coworker! Thumbs-up!
The sheer (lack of) size was a challenge I must admit. Does make me wonder how they were originally mass produced.
Came to me, maybe an idea.. if you use a longer piece of "tubing", and two clamps, with the tubing on the inside, and clamps at the "end" of the "roof", you can clamp an angle with zero gap... I guess, otherwise, filing a small bit in the middle of each piece, to clear the thin through part, the rest of the joint could be zero clearance
That would work, but for thin sheet work especially aluminium you want tacks close together (say 75 to 100 mm) to control distortion, so you are limited in the length you could do that over. I've demonstrated these clamps with short pieces of sheet, but in practice I would probably clamp to a piece of square or angle and have little to no gap. My intent for these clamps is mainly for longer seams (more than say 200mm) or corners where there is a fold that prevents a continous piece of material backing the joint.
Thanks for the video! is it possible to sharpen twist drill bits?
Not on this one. I have a Darex M5 that I use for drills (specialist drill sharpening set up). Somewhere I have a video on drill sharpening that may have that in there. ua-cam.com/video/SOYp3bqErWA/v-deo.html I also have a series on making a drill grinder that my Uncle designed too.
Nice bit of working but if I have to make long slender threaded parts for the clocks i restore Anniversary clocks then i support the other end in a bit of brass to negate flexing as i see your part was flexing but well thought out. ua-cam.com/video/XUhs18MK6jA/v-deo.html
Thanks. I'll have a look.
Fabulous! More great stuff. Thank you.
I just found your channel and enjoy it a lot. I do have a question, over your right shoulder on the wall in some of your segments are some square wood pieces, I was wondering what they were? Thanks
Pipe organ pipes - at one stage I was interested in how they work and so made some.
Thanks so much for making these parts. It's only through the talents of people like yourself that we can keep these engines going. Spare parts ran out long ago. I hope to bench run them soon and will provide some footage of the final results. Then to make a suitable plane for each one. I'm thinking that a Keil Kraft Gazelle would be a nice model for the 1.5cc diesel. 👍
Are you interested in old balsa planes, I have mate who has a couple for sale ( Kit Form )
Looked to be quite tedious work.
A bit time consuming but as long as I did not have to make a few hundred, not too bad
Fantastic tips!
Thanks. Every so often I put a tips video together - mainly stuff that would not stand on it's own as a full video.
Hey Michael. Thank you so much for some of the best simple hacks I’ve seen anywhere. I follow some of the best machinists out there including Curtis, Abom, This Old Tony & I have to say your instruction technique with no annoying music including tips & tricks are 1st rate. I’ve been a hobby machinist for a few years now & like you am a tinkerer or maker in my workshop (garage) & have collected a substantial range of small to large pieces of equipment much to my wife’s bewilderment haha. I’ve only just discovered your very prolific channel & am working my way through from your intro to catch up. Your channel like the aboveboard is now a go to for me & will certainly send others your way. Keep up the great work. Simon (Sydney)
Thanks for that Simon. Much appreciated. If you are working through the back catalogue, I apologise in advance for the quality. The volume in particular jumps around as I did not have a stand-alone mic back then.
Well that takes be back about 45 years, do you know what brand the engines are.
The glow engine is an OS Pet 0.99cc. The diesel engine is an Indian brand. Probably why it has the BA thread.
Probably a bit of an odd question, but do you know where your CVA lathe came from? I picked up a lovely CVA lathe about a month ago in a very similar blue colour to yours, mine was from TRW huyton, had their sticker just above the CVA logo. I'm asking because after doing research into TRW Huyton they seemed to paint every machine they had in the blue colour. Also would be quite cool if our lathes were "related"! :D
Sadly no. I chose that colour myself. When it arrived it was a dingy khaki/green/ brown colour. I went for the blue to brighten the place up a bit. I know it was in the US for a bit, but I got the impression it was a project that had passed through a few hands before making it's way to me.
Great video. Very nice work mister. Yeah that work is on another level. I’m not there yet.
Just takes practice and pushing yourself a bit.
Thank you for posting this series. There are lots of good ideas here. The challenge the home shop enthusiast has is always to see how much can be accomplished with the equipment and skills the individual has, and it's always more than one might at first expect.
I think a lot of this is confidence and knowing it can be done, which I try to show.
Love your videos and ideas. It is great that you show the challenges you had along the way. I am retired and slowly learning machining from teachers like you. Keeep the videos coming, the silent masses are enjoying them!
Showing the challenges (and stuff-ups) I think is essential, as too often people lose confidence when they make a mistake. Editing software makes it so eay to make it look like a 'perfect' job, with everything working just so to the plan. Mis-steps happen to all of us, although I do admit experience does make it easier to recover.
Great idea. You should consider publishing an article on it.
I could, but the number of magazines for home machinists is getting smaller. Just the other day I got an email telling me that MEW was being merged with ME. Most also want original content - that is, not published elsewhere (including I would guess UA-cam). I also don't want to wait the 2 or 3 months for an article to appear before I share with you guys.
Good idea. Beautiful drawings!
An old copy of AutoCAD (circa 2000). Still works, although I really should modernise... One day.
Canada here. The tools are "tacky"enough to stick on cold steel. Happy New Year. Nice work. This Old Bob
Thanks.
A chamfer on the internal edges of both plates would allow them to sit closer leaving a smaller gap. Could a flatted ball work for all 3 types; butt + angle + curved and change it between them to suit the job in hand. If you made them again would you put the slot in last after drilling and milling the vee as deep slots aren't nice to machine and wear the slitting saw more.
Yes, a chamfer would get the top edges closer, although that is always a toss-up between prep time and welding time. A barrel shaped 'cylinder' would effectively be a flattened ball, so yes, that would work. Certainly with them being loose, there is the option of changing them when required. I used cylinders for the demonstrator because they are easy but if I had to do something like the mudguards again, I would be temped to a barrel shape (along with a shallower V) I think you are probably right that the slot would be better last. I lubricate when using them but reducing the DOC is probably a good idea. Always a bit uncertain with slitting saws (particularly the thin ones) as to how deep they should cut in a pass. I like to have several teeth in the cut for smoothness.
Great idea 👌🏻👌🏻👌🏻👌🏻👌🏻
Thanks
I don't know ToT personally, but I can absolutely guarantee that he has zero issues with you or anyone else being inspired enough to make their own version of something he's made in one of his videos! I've been subbed and watching him for 10+ years now and in that time I've seen tons of instances where other creators I follow, in the machinist & makers space, have drawn inspiration from one of his videos to make their own versions and he's randomly shown up in the comments and he's always been humble and super cool about it, to the point of complimenting them on their work and on any changes or improvements they made, but most importantly he's always been extremely encouraging of it. So I highly doubt any of this is coming from him, my bet it's from bored losers who've never felt the spark of inspiration or the urge to build something a day in their miserable lives. Keep doing you mate 👍👍
TOT is cool with the clamps - in fact, he did make a (positive) comment about that video. I'm hoping he takes up my offer and makes a set of these!
Bless you mate, nice little clamps, don't worry about the negative comments, people are idiots, Happy new year and best wishes to you and yours Ralfy
Thanks
Thank you for posting this, I found this quite interesting. This is not completely unrelated to the position I am in refurbishing a vintage mill and learning a lot as I go. Thank you.
It's a good place to start - accessories can get really expensive, really quickly so making your own if you can makes sense
This was very well presented and so that even a beginner like myself could understand, thank you.
Thank you - that's the aim of these
🔩 all the negative poor souls out there, this ain't a competition, it's chering ides like you do. Love your films mate. 🇸🇪
That's my view too.
Interesting and inventive.
Thanks
Very clever idea!
Thanks Ron. I shall watch your channel carefully to see when a set appear...
I think this only good for MIG welding because of the gap. Not so good with TIG.
The gap is bigger than ideal but the samples I've shown were done with TIG. Like most TIG welding, it's practice and technique.
Here's my idea. Check and see. I haven't built one, just a thought experiment. Make them just like the butt clamp. But the pin pulls against a tube. The tube requires a half-depth slot for the blade. The tube then is what presses against the sheet to be welded. More fiddly to assemble, but there's no concern for the blade bending.
In reality, not much clamping force is required on the tube to hold sheet in place. It could probably be thinner - if these were being made commercially where material is cost, I'd do some experimentation to see how much I could reduce the thickness. For the use these will get, not much point.
poor 🛀 lets😠 get a 🐗 for the 🕳🐐. (some just hate how good your ideas are love your the video's )
Sometimes I have problems not coming up with new ways of doing things. 🤦
Why would he mind? These are nice too!
@ThisOldTony was fine with the idea (even commented on that video), but from the increased dislikes I got, I wondered whether some thought I was having a go at his efforts.
I told my woman I was going to make some stainless steel butt clamps, then she got all huffy and said; "Don't bother! I'm not going to wear them!" What a shame.
still counting all the votes but you might have just won the butt clamp challenge! nice work, look sharp!
Thanks for that. If you are up for a return match, the next video out has a variation that you might like to show me up on...
Merry Christmas and nice work on the guards.
Thanks.
Merry Christmas. Did you bend by hand or with bending machine?
I admit to being lazy - I was going to get my rolls out but instead just bent by hand. Once tacked up, it all stayed there.
Merry Christmas, and big love to you and yours 💙🎊
Thanks
Those guards turned out very nicely👌 Merry Christmas🎄
The client is happy, so yes, all good.
👍👍👍👍👍

Hello, great quality video! I am very interested in obtaining your 'Gearing.xls' sheet, unfortunately I havent been granted member access on the metalworkforums - and I have been waiting on this a while now. How else can I obtain your spreadsheet?
11:14 Dividing an edge by any number with no calculations - how nifty!
Haven't used it often, but one of those techniques worth remembering.
Glad you're feeling better. I really need to ask you about the wooden pipes in the background.
Back before my hearing started going down hill, I was researching pipe organ pipes. Those are some I made up. Lacking the rest of the organ, they got mounted on the wall (they work).
@@occasionalmachinist Before my dad passed away, he made a set of pipes for a monkey grinder organ. He never got to finish the organ, but after he died, mum had them made up into a working organ.
Get well soon!
In school they taught us odd leg calipers were also called hermaphrodite calipers.
I've heard that name for them and also odd leg jennys. Not sure how widespread some of these names are, but look deeply enough and there are bound to be others
The tape measure offset is the only thing you and the the class I paid for have in common. I need a 3.5x refund.
Hope your feeling better soon. That video took me back to my technical drawing school days. I don't think they teach it nowadays in the UK.
I'm not sure how much is taught in Australia either. Not everything can be done with a computer.
@@occasionalmachinist I know, Drives me mad, no woodwork, metalwork in fact anything involving machinery. Kids nowadays don't know how to use hand tools, grandad shows them!
Thanks to all for their good wishes. I'm slowly improving although it's knocked me round a bit. Fingers crossed, back on the tools next video.
