"This is a slip fit. Typically they have about a .0005" difference in size. The wires on an edm machine range but are generally .02 to .05" but I can get different sizes. But yes these were cut from 2 separate pieces. That's not the same piece of material the spade was cut from."

When I did this experiment here with a longer plastic tube for the propane and air, the can that shot out made a deafening bang and that curved bottom on the can that shot out was completely recurved the other direction. It's strange how a longer tube builds a better hammer wave or whatever you would call it. I guess it's kind of like that guy's plastic bottle cannon, that confinement really helps the thrust.

I was realy excited to read that article, until I saw the 100 grand price. Not quite mainstream. 100 grand will buy you a lot of nice machining tools
