I was needing to make a vacuum chuck for my lathe and didn’t want to use a faceplate or fool with using a nut fastened to the chuck.
The quick n dirty is that I used delrin I had laying around, a 4” PVC union, and some weather stripping to make my vacuum chuck. The majority of the process was completed using my wood lathe.
