Anyone know of a good shock pump tutorial?

So i got some brass roundstock i intend to make hybrid with, but i dont have any type of pump, so i thought i'd try my hand at making my own and figured id look for some tutorials so if anyone knows of any then tell me.

Gippeto offered this stirrup pumpsome time ago. It's a high quality unit.

Cool thanks, I was going to make a short stroke pump and drive it with a camshaft and a flywheel.
