RE: How fast will this Diamond Dust go??
Mount the rear of the pipe on a hardwood pedestal. Cross drill the pedestal near the top for a piece of music wire, basically it's a peg that sticks out each side of the hardwood. Then slice off a thin piece of pipe coupler material and use it like a rubberband to secure the pipe to the pedestal by stretching it around the stinger and over the ends of the peg.
