Great feedback and might explain the wheel sticking... I was just about to hit the purchase button for the MSK-250 on Amazon! Let me check that out first and if not I will also contact Tormek tech support for troubleshooting.

General Tormek Questions / Tormek T7 Setup - Grinding wheel either too tight or too loose
October 22, 2025, 11:20:48 PM
Hi all,
I've had a "mint in the box" Tormek T7 in my shed for many years, and am just now setting it up. For installing the stone wheel, it came with a supplementary yellow instruction sheet which states to "mount the wheel with a 3/4" wrench... tighten the nut by hitting the wrench a few times with a hammer. Do not tighten by pulling the wrench as there is then a risk of damaging the center of the drive wheel"
OK... that seems a bit weird using a hammer to avoid damage, but I followed these instructions to a tee. Running the machine, the nut that holds the stone wheel kept unthreading itself and falling off. So I tightened it a bit more... the wheel now ran slowly, then after a bit of tool grinding, would stop altogether. The motor would hum but the wheel wouldn't move. When I tried moving the stone wheel by hand, there seemed to be quite a bit of torque required to move it, much more than I expected. So I loosened the nut slightly and again, when I turned the machine back on, the wheel would start slowly spinning, but the nut would loosen itself and fall off.
I'm at a loss - can anyone help? Anxious to get started sharpening my chisels and realize my investment in this machine!
