Here’s an example of a preliminary drawing that I made in Sketchup. The idea is for a single press fit tungsten ring to replace the 100 (now 96, to have 16 [the number of cathode rods] as a divisor, fyi) tungsten pins, which continue to cause headaches.
Instead of a continuous upper edge, however, Eric wants to add a zigzag of 96 evenly spaced points, each 90 degrees, to duplicate the pin functionality but with much easier assembly. So I’m working to improve my Autodesk skills so we can get quotes on that more complex design, and in the meantime have found this as the closest analogue. So folks don’t have to wonder what the design in those .ipt files looks like, a hole saw looks like this. Our right angle points are actually a bit simpler than these wavy sawteeth.
