The tool post (or stem) is the vertical shaft that connects the tool rest bar to the lathe's banjo (the movable base on the lathe bed).
The height can be adjusted so you can set the tool rest to the correct height for your cutting tool. It can be paired with any compatible crossbar, which simply screws on to the top. Spanner flats are included to aid fast removal of the crossbar. You can also use a hex key in the bottom end, instead of a spanner.

A locking collar is provided which can be used to ensure the tool post returns to the same height in the banjo when you adjust the angle of the crossbar. Particularly useful for bowl turners.

The modular tool rest range is a 2 part system. Any crossbar can be paired with any stem. You can use one stem on your lathe and just change the crossbar to a different type when needed.
