Plinth Block, Mini Lathe

Plinth Block, Mini Lathe - Main image
$15.22 $24.95 In stock

This steel mini lathe plinth block will add rigidity to our tool post mounting. It replaces the compound rest, and you mount a standard OXA quick change tool post (QCTP) directly to it!

The plinth block must be used with a quick-change tool post. It will not work with the standard 4-way tool post. This is not as tall as the compound rest so that tool holders are in the middle of the adjustment range on quick change tool posts. (2) M6x25 Socket Head Cap Screws are included. Threaded for M10 QCTP stud.

- Mount with the two threaded holes toward the chuck.
- Use the inside threaded hole for small work.
- Use the outside threaded hole for large work.
- Use the center threaded hole for full support when the tool post is at an odd angle.

The mini lathe plinth block is designed by and manufactured exclusively for LittleMachineShop.com. It will fit HiTorque mini lathes as well as SIEG C2/SC2 and C3 mini lathes including popular models sold by Harbor Freight, WEN, Micro-Mark, Grizzly and others.

Ella P. ★★★★★

Swapped out the compound rest for this block and my QCTP sits rock solid now — no more flex on heavier cuts. The steel feels properly machined, and it’s a direct bolt-on for my OXA tool post with zero fiddling. Exactly what I needed to stiffen up the setup.

Penelope ★★★★★

Bolting this on took maybe ten minutes and the tool post now sits rock-solid with zero flex during cuts. The fact it replaces the compound rest entirely is a huge plus for rigidity, and the OXA mount lined up perfectly.

John ★★★★★

I was a little worried about flex in my mini lathe setup, but this steel plinth block really stiffened things up after I mounted the OXA QCTP directly to it. The machining is clean and the fit was spot-on, so no more chatter during light cuts. Money well spent for the rigidity gain.
