After taking the summer off from my project I finally have gotten back into the shop. I had a few hours available today to do some machining. I started back with machining the Cam. It started out as a piece of 1.5” cold roll that I turned down to 1.25” and parted off to 1” long.
I then had to drill two holes as well as open the top portion up so only the bottom portion of the holes where threaded for 8-32 set screws. Then I tapped the holes using a small tap handle the I built last spring.
After those holes where done I needed to stand it up vertical and drill a .500 hole directly inline with the two holes but .250 off of centre to give me the cam action. My DRO made this a easy operation. I drilled the hole out and finished it with my .500 reamer for the perfect fit on the crank shaft.
