Hi
Got a big bit done it is nearly a runner
Time for a fly wheel
I had a 8 inch disc with a hole in it about the size i wanted but a bit thin
A centre boss was turned up on my boxford
The big bit was possible for me to machine but it would have taken a long time
Rob Wilson kindly offerd to rough it out for me on his referbished cub lathe
(Robs idea of roughing out is different from mine) needless to say it turned out perfect.

Time to cut a key way in the crank

The proportions are just right

Could not resist making it spin around

Just a ecentric strap and some linkage should have it running
