Adding Locking Wheels to a Cast Iron Grinder Stand

Harbor Freight used to sell the same grinder stand as the Grizzly H7763 where the base is a hollow casting, complicating wheel mounting. Most stud mounted wheels only have a bit over an inch in stud length and more than two inches plus an enormous fender washer would be needed to mount on this base.

I made aluminum adapters to go from the 1/2"-20 wheel studs on the 4 in. Hard Rubber Heavy Duty Swivel Casters with Brake Harbor Freight Item #90999 to a 3/8"-16 tapped hole. The adapters are about two inches long and easily clear the the hollow casting. The mount is very solid but the assembly is top heavy and a bit tippy but still works well with the wheels locked.
