Master Mill V Belt Pulleys

Opted to use a toothed belt instead of a poly-v.  Driven pulley is nearly done.   Still need to cut the key way.

A pair of  4 inch pulleys should work With the belts from the large drill press.

Cut the key way on the Sidney using a sharpened key on a boring bar.   Lath not under power.

Could not use the boring bar on the Atlas because the bar was too small for the holder.  Shimming with aluminum flashing did not work.  Moved to the Sidney which is in theory more rigid.

 

Finished the driving pulley.  Left had tap on 1/2 hole and bored the rest out to fit the larger part of the shaft.   Motor rotation will unscrew it so I added permanent thread locker and tightened it.  Let it rest till tomorrow.
