Flywheels?

[Doogle]

Am tackling the flywheel for my first tin can engine. Suggested by the plan I am following is a CD. Would it make it any difference to use a top of a bottle jar? About the same density but different diameter (smaller). Reason is I can make a better fit if a drill a hole in a jar top.

I make CD flywheels by gluing a 1" x 1" scrap of tin so it covers the center hole of the CD, then I attach another CD so the tin is sandwiched in the middle. Then it is pretty easy to attach a wire nut to the tin, drill a small hole, and you are good to go. You can glue it all up with 5 minute epoxy and be running in no time.

If you drill the hole before you attach it, it is much easier to find the center.

You can almost make it out in some of the pictures here: http://sites.google.com/site/stirlingbu ... can-engine

Thanks Jim, I'll try it out. Great solution.

I use the ends of tin cans with an electrical terminal connector epoxied in the centre. Works well and can
be easily fitted/removed.

doogle, you could use MDF, or wood if need be, there's little in the way of ridgid material you can't use. Ian S C
