Looking for bench grinder parts

[WhoWhatNow]

Anyone know where I can find the arbor flange (washer) for a 5/8" shaft grinder? It is for a Rockwell 23-104 7" bench grinder. I am missing the left hand nut and flange. A quick check of McMaster-Carr did not find one but I may not be searching with the correct key words.

Your best bet for the flange washer would be to get one from Baldor.

The left-side nut on the old 7" Rockwell grinders is left-hand Acme thread. It's the exact same thread as used on the Unisaw arbor (not the current model, the old model made from 1939 until a few years ago).

A guy named Frank Skinner is making replacement Unisaw arbor nuts that will also fit the left-side arbor on your grinder.
