yo I think the diaphragm idea can be redeemed, think about pressure washers they can produce several thousand psi in hydraulic pressure, in fact even the cheapest (under $100) electric ones produce more than 1000psi which pimpmann is trying to reach, the two easiest ways I can think of to convert the hydraulic pressure into equal pneumatic pressure are:
a)inject the hydraulic source into a sealed tank of air, thus compressing the air inside. however a cheap large volume tank that can handle such pressure is hard to find, draining the water may take some time, and when using it to fill a chamber you face the challenge of trying to fill the tank as much as possible, without over filling
b)build a diaphragm system, the control valve could be controlled by a timing circuit although it isn't very efficient, you could figure out how to put a momentary switch in there
DIY HPA route? (Diaphragm pump?)

I was recently thinking about HPA, and found this.
My next idea involved calculating the force required to pump as a function of piston position. I ended up with some really ugly equations involving the angular position of a motor, converting torque into pound force. toward the end of the stroke, the force skyrockets (theoretically to infinity) I then related the angular position to the force required to compress the air. I ended up with an equation of the net force as a function of angular position. I can give the equations if anyone wants.
That drove me to think that using the up stroke to compress an air spring would give a large advantage by spreading the required force over the full rotation, rather than half of one. This and the previous idea only only work on single stage pumps.
A multistage pump would be very feasible with this gear head pimpmann has. Does pimpmann have a lathe?

This post and link seem odd. I may be crazy, but on the side of caution I scrambled the link. I'll figure this out soon. If I'm crazy just tell me.
