Hi all, I have built a laminar flow engine which wont run when piston is connected to fly wheel, however the piston oscillates one its own when disconnected from fly wheel. Any one has a clue what the problem/solution might be? Alex

Hello every one! I've been away from this forum too long and thought it would be time for a comeback. Still looking at different engine designs and no complete engine yet, just various parts laying around. Among them a cylinder I made some months ago. Can't remember which ozzy it belongs to so...

Thanks for your input! Wes, I live in Sweden so it might not be worth shipping, but thanks anyway! ;D Teflon is easily available here so I think I'll have a go with that.

Hi gang, I want to build a laminar flow stirling engine but can't find graphite around here. Is there any other material which can be used as a piston? Teflon came to my mind but it might not like the heat.

I sure am! ;D

Wow, you're quick! I'm not really sure how to grind it. Do you have a picture or link?

Hello group! Just ordered a 4-jaw chuck, but before contruction can begin I need some very small boring bars for machining the cylinder barrel. Do you know where these can be purchased? Thanks and merry Christmas Alex

Hi all, Was going to drill a hole through a little fly wheel that I'm making for the Tiny engine. I put the B16-MK1 morse cone in the tailstock and then mounted the chuck. I made a final check that all was ok before start drilling, well it wasn't. The MK1 cone had some movement in the...

Thanks a lot guys! I retighted it a few times and eventually I got it right. not perfect but almost. Tomorrow I'll check the chuck for wobble. Again, thanks.

I have nothing to measure with so it's hard to say. But it's certainly not more than 1 mm (.04") at the end of a 50 mm (2") long, 20 mm (3/4") dia piece.

Hello group, Got my lathe the other day. How I try I cannot get the work piece to line properly in the chuck- there's always some minor wobble. Anyone knows how to solve this?

Is a milling machine required to build this engine?

I think that it's easy to cut corners a bit when working with hazordous materials at home. I handle carcinogenic and other less good chemicals, such at mastinox and MEK, at work. Protection equipment is always available. When I'm home and lack a mask or what ever it may be I keep on working...

One tip when bending tubes is to fill it with sand and plug the ends. This will prevent the walls from collapsing.

It'll be interesting to follow the progress of your engines. Don't forget to take pictures. :D
