Subject: vacuum bazooka


What is the success rate people are having with their bazookas? I have
suspended taking mine on the road because it only works about 80% of the
time. My hearing is not good enough to hear leaks is a big problem, I'm sure.

I use the packing tape and I have machined end fittings to allow more
surface area for the tape to stick to. To allow it to be portable, it is in
two, four-foot pieces. One length has a coupler cemented in place. When I
connect the two pieces, I use vacuum grease and wrap duct tape around the
connection that is not cemented. It is an awesome road show demo but a demo
that is inconsistent in that environment is practically useless.
