I've just got myself a DIY blast cabinet and connected it up to my unused pressure pot.
I made a version of Brightspark's metering valve and initial results of the whole seem good.
But I don't like the ball valve on the end of the blasting pipe and I would like a pinch valve.
Looking on the net it seems all these valves are in the US of A and so are too big and too expensive.
So I'm just thinking aloud here and asking for your thoughts of perhaps using a cars brake caliper as the basis of an air operated valve. Something would need to be made to hold the pipe and an anvil(?) to attach to the piston and a 3 way pedal valve.
Thoughts any one?
