I acquired most of the parts for this Hold Fast v810 vacuum generator. It has the generator, hose and headstock insert. I also has an optional PSI gage for the compressed air input. From what I can tell, it just lacks the cup chuck. Before I make or buy one, I decided to make sure the generator worked. So, I hooked up my little compressor and carefully put my thumb over the end of the rod. Meh. I've never done this before but I assumed it would give me my first thumb hickey. I've uploaded a video of the test.
I just cant imagine this will hold a piece of cardboard onto my lathe, let alone a bowl. Input? What's wrong?
