This wheel works perfectly for your own grinder build, including our own No Weld Grinder plans. The wheel has a slight crown to help with adjusting the belt tracking. The bearings require a slightly smaller washer next to them so the washer doesn't bind against the bolt or tracking arm. These washers are called 14gauge Machinery Bushings. We sell these in packs of ten. You can use other washers to stack on either side of the tracking arm to help align the wheels in a vertical plane to help with belt tracking.
