I love the design Bernd. Care to share the details on how you designed it? I may want to have a hand at trying it.

The wheel dia. is 1.250" so I made the inside of the flywheel 1.000". The hub I made .375". I drew this up in Autosketch. I then played with the circle drawing part until I had a round ring that would fit 4 times in the dia. between the .375" hub and the inside 1.000" dia. of the flywheel. The four smaller circles were added the same way.
I used a piece of brass rod about .250" thick and bored it to a .188" depth or there abouts. This allowed me to align the parts flat. Koso Hiraoka does something similar in his building of the three logging locos he's built. Much easier to assemble parts this way. Hope I was able to explain it good enough for you to understand.
Here's the Autosketch Drawing

Easier? I'd go blind or nuts looking for them. Sure at least 2 would find their way to the floor

There is a simple cure for that. Make em outa steel. When ya drop em just send that big a??ed magnet after em. That will get them every time as long as they haven't pulled an Elvis and left the building. You might be suprised at what else you might find! :bugeye:
If you don't like steel finish then just paint or plate what ever yout heart desires. :lol: :lol:
Cheers :beer:

Well I was going to work on the cylinder tonight. Notice I said "was".
Well I got the stock cut. I did a quick look at the print and saw the .890" length. Ah, 1.000" aught to do just about right. Cut two pieces.
Set up the Sherline in mill mode and clamped two parts in the vise. Figure if I mess one up I'll have another.
When I finished milling one of the blocks square I figured I'd better check the over all length. So out came the print. A much longer look and I discovered that the over all length is not .890" but 1.020". :bang: :bang: :bang: :bang:
So now I have two pieces to use for two wobblers perhaps or maybe a ................
Next time I better check the print a bit closer. :doh:
So that's it for tonight. Gonna' surf the net for a while.

Bernd,
Love that flywheel! You've made a mistake there though as now the rest of your engine has to live up to it! :doh: :)
