Vacuum Adapter
$ 109.00
A vacuum adapter is the rotary coupling needed to connect a vacuum hose to the lathe spindle. It simply slides into the handwheel end of the spindle and is held in place with two 0-rings. The threads for the fittings are standard ¼” NPT (National Pipe Thread), available online or at any hardware store. This is the only part of the vacuum system we sell.
The stem of the vacuum adapter is 5/8″ and it also fits the popular Powermatic 3520 series of lathes (A, B & C).
There are a number of good online resources that show how to set up a vacuum system. One Robust recommendation: get an actual vacuum pump instead of a vacuum generator that runs on compressed air. Vacuum pumps are quieter, more reliable, and generally pull a higher vacuum.
