The bondo piston is especially neat! (People like me don't have the patience for that!!) Very cool build! I have a similar golfball...

Usually ABS isn't pressure-rated, but I believe it is easier to get pressure-rated ABS in colder areas due to the fact that PVC gets brittle at low temperatures. Be ready to shell out the $$.... Unless the pipe has a pressure rating written on it, it is UNSAFE to use it under pressure. Like the cann...

I did actually try that once with a piece of tennis ball, but oddly enough, the bumper would get pushed back into the QEV :shock: and I would have to open the thing up and yank it out with pliers :D You definitely have the right idea though... I've gotta think of something... Taking that thing apart...

I got my router for free, just ask around and I bet you'll come up with something. Old folks are your best bet because they often get rid of things they don't need that are invaluab...
