$27.34 $36.95 In stock

This is the bottom half of the compound rest on the 20 TPI mini lathe. Fits Micro-Mark mini lathes and HiTorque 4200 mini lathe.

The thread is 20 TPI so the compound advances 0.050" per revolution. Use with a dial that has 50 divisions.

This part has a second set of holes that moves the center of rotation of the compound rest to help eliminate chatter. Use the holes nearest the end of the part.

Richard O. ★★★★★

Replacing the old compound on my 4200 was straightforward, this bottom half lined up perfectly and the 20 TPI thread bite is reassuringly positive. The 0.050" per revolution feed is exactly as spec'd, making fine adjustments predictable. Happy with the fit and finish.

Sophia ★★★★★

The threads engage so smoothly on my HiTorque that the 0.050" advance per rotation feels precise, not sticky. This drilled bottom half lined up perfectly with the existing holes, saving me from any filing or re-drilling hassle. Exactly the fit I needed to get my compound back in action.

Mia Q. ★★★★★

The machining on this bottom half is precise—the 20 TPI threads engage without any play, and the drilled holes lined up perfectly with my existing setup. It’s a solid, no-fuss replacement that feels just as sturdy as the original part.
