I am going to try build a space warping device of my own design. A couple of components are a custom vacuum tube. So I am asking for suggestions on what are the best pumps for making a high quality vacuum on the cheap? I also need a cathode at them moment I am looking for a tungsten lightbulb for the tungsten wire as minimum order size on Alibaba for tungsten wire is much more than I need.
