Belt Grinder D-backing plate for 2x72" knife making grinder with bolt axles

Description

Start your homebuilt grinder project off with a rock solid backing plate!
D-shaped backing plate for flat platten assembly, this one with even deeper reach for slack belt grinding. The plate is precision cnc cut from 1/2" aircraft aluminum. Wheel mounting holes are 1/2-13 precision tapped to ensure that axles are perpendicular to the plate. The centre mounting hole is 1/2" diameter, the slots for a flat platten mounting bracket are 1/4" wide & 6" apart, the u-shaped adjusting slot accepts a 3/8" bolt or stud. The axle holes are 10.5" center to center apart; if you mount two 2" diameter wheels on this backing plate you can easily mount an 8" long by 2-1/2" wide flat platten between the wheels for a large grinding surface.
We include 2 grade 8 bolts, 3,5" long, 1/2-13 thread, with 4 nylon spacers, 2 1/2" washers & 2 half-nyloc nuts. Also available with wheels & a platen mounting bracket.
