I use "ultram' from mcmaster...Great stuff. cheap and machines well. Made tons of plugs with it and i like it much more than corian. Comes in rods of different sizes. Try it!
 
Do you mean Ultem? I couldn't find Ultram on McMaster-Carr's website.
 
Steatite also looks like an ideal insulator, but I am not sure it is machinable. I could not find anything directly, but what I could find looks like the machining is done with diamond tools and diamond grinding. Does anyone have a better answer on steatite machinability?
 
Whoops! My bad...yes...Ultem. Ultram is my pain killer pills for my foot...they come in handy too though.
 
Hey Steve,
Your note didn't make it clear as to what occurred or meant when you "dropped it". As I recall, it was so small that it wouldn't have had enough energy from gravitational pull to actually "break" if it hit the floor unless you then stepped on it. So I for one am going to suggest that it got "lost" rather than broken. I could supply a really large magnifier to hunt for it if that helps. Hey, on the other hand you made it sound so easy to do, just spend another week and make a new one !! hahaha


All done Brian! I even recorded the test
