Now faced with the task of making eight circular plates for the ends of the rocker beams with a concentric hole in the center .
I elected to make a die to punch them out of plastic.
Boring hole in end of apiece of steel rod with a center drill - this bit is the same diameter as the finished disc will be.
Turning taper on outside of die with the compound tool post to produce a sharp cutting edge .
While still in the lathe chuck a hole was drilled through the die in order to be able to drill the concentric hole in the disc .
Punching out discs .
Drilling through die center to produce hole in disc .
The discs ready for laying out bolt circle - bolt heads will be done with Evergreen styrene hex rod .
More tomorrow.
