(Sorry for my poor english) Thank you matt for these fantastic video. I've spend a very good moment watching it. I hole you'll send other project and video. Thank from Savoie in france. Pascal Turneralp
just built that motor only with diffrent materials and spex , still has a brass piston. only part left is figuring out the intake and exhaust ports.......wasnt as nice as yours but the general idea is the same being that I didnt build to your scale, am seeing thiers 3 holes for the intake and exhaust so when the wobble starts the 2 holes have to line up with the 1 hole as it goes back/forth right??
I'll try to explain. 😅 There are 2 holes in the column (lets call them A and B) and 1 in the cylinder (lets call it C). As the air enters through (A) into the cylinder (C) it pushes the piston down moving the cylinder into a position which aligns (C)&(B) where the air is exhausted and the cycle starts again. Hope that makes sense? I'd love to see your build btw. 😎
@@machinist_matt dont quite get it yet.............so when I drill the 2 holes in the column do they line up with the 1 hole in the cylinder?? I made some wobblers by tubelcain , is it anything like that??
@@machinist_matt ok thanx for that, if I got it right >>>>>>>>>>> when the main tower with the 2 holes leans left its putting air thru the 1 hole in the cylinder and visa versa right?>>>>>>>>> still trying to figure out where to drill the 1 hole in the cylinder in relation to the 2 holes in the main tower
Hi Matt. Sorry, but when you used different grades of sandpaper to polish up was it normal wood sandpaper or wet and dry and did you use any compounds like solvo autosol or brasso?
@@machinist_matt ha ha. I wish fella. No, seriously, I’ve been making a bench, mounting lathe, and been buying many extras. I’ll keep you update though.
Hi Michael. I have a large box of random springs I bought several years ago. I can't remember where I got them unfortunately. 😬 The spring from a biro pen will probably be about the right size.
Thanks Matt. I’m gonna have a go at making one. Got all the materials however, base plate is thicker material so I’m assuming I just need slightly longer fixing screws?
Links to all 5 parts of the video in the description. 👆⬆️
Found your site, looking forward to see the other segments 👍 thank you Matt
Excellent close up camera work. Silence is golden.
Thanks for watching. 🙂👍

Bonjour, merci d'avoir regardé ! Ton anglais est bon. Bien mieux que mon français. 👍
this is just a delightful watch
Thanks! it means a lot to know people are enjoying watching my videos. 👍
Beautiful build mate!

@@stanburdick9708 Yes that's it you got it. Generally the single hole in the cylinder is bang in the middle and at the very top of the stroke IIRC. 🙂
Tidy build. I just started a build of a ST oscillating engine on my channel.
Thank you, I'll take a look. 🙂👍
Hi Matt. Sorry, but when you used different grades of sandpaper to polish up was it normal wood sandpaper or wet and dry and did you use any compounds like solvo autosol or brasso?
Hi Michael
I used ordinary wet and dry. No polishing compounds or anything.
You must be near finished now? How did the build go?
@@machinist_matt ha ha. I wish fella. No, seriously, I’ve been making a bench, mounting lathe, and been buying many extras. I’ll keep you update though.
@@michaelchatt2639 Ah yes, I forgot about the new lathe purchase! Be good to see the finished article!
Hi Matt. Have you a link for the spring please?

The spring from a biro pen will probably be about the right size.
@@machinist_matt thank you matey.
Does your lathe have “ auto feed”?
Which one? 😂☺️
The lathe here does but I rarely use it.
Where can I get the part list and the tehnical drawing with sizes ?
Hi, the plans are from the book "Cowells 90 Lathe Handbook". The construction is mainly brass and silver steel or "drill rod".
Can I ask what lathe this model was made on please?
Hello. Yes, it's a CJ18A mini lathe.
Thanks Matt. I’m gonna have a go at making one. Got all the materials however, base plate is thicker material so I’m assuming I just need slightly longer fixing screws?
@@michaelchatt2639 Yes a thicker base and longer screws should be fine. Good luck with the build! 👍
Thanks Matt. Last question is how you achieved the polished finished which is clearly seen in pt5 when you assemble. Thanks.
@@michaelchatt2639 I just used various grades of fine sandpaper. The finest being 1200 grit to give it a lightly brushed finish. 🙂
