Need a little cleaner for the Prentice loader.
First, find a piece of suitable scrap.
Engage the services of a suitable mill. If this were any thicker, I would clamp to the table rather than hold in the vice.
Separating from the solid.
Outer lip will be cleaned up on the lathe.
Blank boss in the air horn. In the original application, this motor had a stub bolted on top of this flange. See threaded hole to left.This is where you wish you had a riser block on your milling machine. A good reason to have a bunch of short tooling on hand.Center and drill for tap.C-bore for show.Tap.And how I think it’s suppose to go, based on the last one I made for the sawmill motor.Of course, that motor is a 4-71, and this is a 3-71, which does not have the same clearance. This is what happens when you don’t work from drawings.
