Oh dear! How does it work Stew? Don't understand it! :scratch:
Just had a closer look at the drawings - I like it! Will give this one a go when get my workshop sorted.
You got one working yet Stew?
also the contact area on the bearing is only small so I'm thinking I may change the design to increase the contact area so you get a better fit without slop.

Did you press fit the sleeve (the .188 diameter tube) into the cylinder/frame part? I think that's how it's supposed to work (and how I am making mine) so that you get the full length of that sleeve as a bearing surface. No instructions along with the plans, and not even any tolerances specified, so it's not completely clear how it is supposed to go together. I'll have to have another look at the plans.
Stew, may I ask how long it took you to make the parts? The reason I ask, is because I'm making the same engine - with a few of my own touches.
I'd like to know just how fast some of you guys can whip out parts.

To make all the bits for two engines it took me about 6 hours, I've been playing around trying to get them to run and to remake bits about the same length of time I've still got a couple of hours more work to do over this week end to get them running the right way up.
Hope this helps

Then instead of a lose bush thing that the drawing shows I made a bearing with a 4mm hole and shouldered to fit into the cylinder, I soft soldered this in place using solder paste, great stuff this for little jobs

Regarding youtube - if your on broadband it really should be timing out! How big is the vid?

Stew,
I haven't seen the video yet but well done, keep picking up lots of tips and tricks from you! I have a pot of that solder paste and it is brilliant, I use it as a flux more than anything, I always feel the need to feed a bit more solder in for good measure!
