Shock pumps? for volume?

[iknowmy3tables]

I need a portable way of monitoring and mantaining the pressure of my AT4 currently I don't have any tire gauges on my pumps and my large pump so I was looking into buying a shock pump because they are reasonably priced and I could finally do some high pressure projects.


here's what I was thinking, I have a chamer and pilot with about 9 cubic inches in volume, I would use my old-dying-gaugeless stirup pump to reset the piston and pump my cannon to ~10 psi, then I would attach the shock pump and pump to no more than 60psi? how difficult would this be?

Not a lot of effort on the stroke, but it would take you a while.

Quick and dirty calculation, let's say the pump has a stroke volume of 0.3 cubic inches, so you get a 0.5 psi increase every stroke, meaning that taking it to 60 psi would take 120 strokes.
