I had a little trouble getting here. It has been some time since I registered but could never get the email to confirm untill the other day. I have had a cumins 7x12 and a harbor freight micro mill for about 5 years. never got serious with them until recently. I intend to make a sort of copy of henry fords first engine. Today I have been working on a flywheel. I started with a 6 1/2" 1" chunk of cast iron. have faced both sides and outside and then thinned the center in preperation to cut 6 spokes in it. It may be a bit large for a 7/8 piston but was the largest I could fit on the lathe so I can go bigger on piston if I have too. I have taken a few pictures and will post when the flywheel is done. I intend to bore for a 1/2 shaft. John
