2x72 Grinder Wheel SetI am building another low-cost 2x72" grinder and I am super fortunate to have made a friend at Oregon Blade Maker.
durable grinder wheels for a low cost 2x72" DIY build.
These wheels are computer engineered, glass-filled nylon (durable composite plastic) with 1616RS bearings.
The wheels in this set are two 2-1/4" wide x 2" and one larger diameter crowned 2-1/4" wide x 3" which is designed to assist in belt tracking.
The wheels will mount with any 1/2" bolt. Plan for three 1/2" NC x 3" to 3-1/2" grade 8 bolts and suitable nylon lock nuts and washers.
These are low drag and spin freely.
Of course, the OBM glass-filled nylon wheels are not going to take over the aluminium premier wheel's top spot in roller Olympics, but these OBM nylon wheels offer value that cannot be denied.
