[Shop-talk] SPAM: 4.54" GRINDER SPINDLE ADAPTER

1/2" is almost the tap drill for 5/8", meaning a sleeve would be weak.  Using a standoff type adapter would probably not be a good idea either, since it moves the flap wheel farther away from the grinder, which will increase vibration and the stress on the bearings.

Might be best to just put the grinder with the 1/2" shaft up on eBay and buy another grinder with 5/8".

Another alternative might be to machine a new shaft with 5/8" threads.
