I don't know that your motor can handle variable speed.

If you bought a 3450 grinder too bad. Way too fast. Even 1725-1750 in my
mind is too fast.

I use a 1725 rpm grinder with a coarse white friable alox wheel.
Haven't burned a tool yet. I don't even use a water dip.

If you have a grinder 3450, get a set of pillow blocks, and sheaves and
step down the speed. Remount the stone on the new shaft Use a sheave
like used on drill presses so you can adjust your speed.

Or use a smaller wheel. Halving the diameter has the same
effect as halving the speed.
