I didn't take any pictures of the build but it was all pretty simple. Will try to post a few pictures of the finished product this evening.
I cut a 2"ID brass tube down to 18", turned the ends down enough to fit the flange/nut side of a 2"ID "copper union fitting" over each end, then TIG welded the fittings to the tube. I found a flange side of a 1 1/2" iron union fitting which was the right size to fit in the 2" copper union fitting, then used it to attach a 1 1/2" brass/stainless foot valve/strainer to the bottom of the pump tube.
For the pump plunger, I turned down a piece of 1"ID brass tube and threaded it for 1" straight pipe thread (not tapered pipe), then made 3 internally threaded brass bushings to fit inside the cup leathers I had. These brass bushings go between each of the cup leathers (and underneath the lower one). I tapered the inside of top of this tube and turned a brass check valve to fit. It sits just like a valve in an old flathead engine except for the fact that there is no spring, just gravity/pressure operated. To screw onto the top, I made a threaded piece with open sides which squeezes the top cup washer against the top brass bushing, allows water to come through the plunger/check valve on the downstroke, keeps the check valve from coming out of the plunger, and gives me a place to attach the sucker rod.
