SUPER SPACER INDEXER, CUSHMAN, 8", HORIZONTAL-VERTICAL
Used but not abused. This is a Chushman Super Spacer built to outlast you and me. 
It has a Cushman Chuck #1862 with two piece hardened, reversible jaws. 
It has very smooth geared down adjustent of the jaws. 
It has a 360 deg. graduated ring with vernier plate. 
It also has a massive, positive lock break.
It has an impressive 2 1/2" I.D. 
At one time someone cut a .400 x 3.700 clearance notch in the base.
I found out why this was cut out while taking these pictures.
It is clearance for the jaws, when swinging a 10" part, holding on the outside. 
Would prefer pickup, but could ship UPS Ground.
