I have a themac too. a different older model. mine is primarily for inside grinding.
you know you can change the pulleys to increase speed. just swap which shaft they are on.
great little precision grinders.. just make sure to oil it. I use spindle oil.. not sure if that's right.
Yes, I have long inside grinding spindles - some of which are not listed in their catalog. In fact the as received J-4 had a 2 - 5 pulley setup with a 449 belt (also not in the catalog). So, I have 5 pulley sizes for the J-2A1 & J-4 + 2 extra spindles + 3 different sized replacement belts & a modicum of arbors for a tool drawer's plethora of stones. Alas, I must make more stone mounting arbors to fit my needs though. Part of the fun though!!!
