That made a great looking flywheel!

Well, I had to make my cams a bit bigger because I made the crankshaft too big diameter.
I needed about a 2" piece to start with.  I didn't have that big, but Dad had a piece of bearing bronze that was 2"
I silver soldered a 1.5" brass in the 2" bronze.  You can see the different colors after I turned in the lathe.

Next, back to my mill to profile the cams.
I made a fancy little fixture to hold the bearing surface while I shaped the other surfaces, and bored the .75" hole.

The design calls for an end cap.  At first, I was happy to see this.  I thought it would be quick and easy to make it this way instead of making the eccentric strap out of two pieces.  I think next time I will do it the traditional way, (eccentric strap in two pieces)

I cut the shoulder off one of the cams so it would fit snug against the frame rail and I could use a straight connecting rod.  The other cam, I will have to put a bend in the connecting rod.  That should be fun (I hope I can get it to look nice).

The last picture, the silver solder let loose right by the set screw.  I'll have to set it back up and make a flat spot there.  Bummer

Thanks!  I was kind of worried when I seen  how far off the spokes were and the wall thickness.  But it really did turn out ok, and I can find a piece of brass or pipe to add more mass to it later.

The flywheel and cams both turned out very well Dennis.  :ThumbsUp:

Well, I got all my pins made to connect all the linkage today.  Then I got the straight rod threaded and fitted to the valve.
I have to bend the other rod for the valve about .75 offset.  I tried with some 01 tool steel, but 01 don't bend very good.  I'll have to try again tomorrow with some cold rolled.

The O1 would need to be heated to take a tight bend.

I got the shaft bent, and I think it turned out pretty good.  It only took me 4 tries. ;D ;D
Now I need to put some threads on the valve linkage shafts and I will almost be ready for a first time start up.
Then take apart and add in a few oil cups, and fix a few minor problems.
