I bought the parts and put the pump section together the other day.
Here are the parts laid out in the order they go together.

I haven't taken a pic of it put together, but I will try to do that in the next couple days.
The smaller section (piston) is put together and goes inside the larger section (body). The threaded cap on the top of the piston is factory made with 4 stiffeners between the threads and the slip. I drilled out everything between the stiffeners, threaded in a 3/4" x 3/8" reducer and then threaded in a 5' length of threaded rod.
The piston is inserted into the pump, and the pump is reduced to 3/4" pipe.
As the piston is lifted it pulls water into the body past the foot valve. As the piston is pushed down the marble breaks the seal in the bottom of the piston (seals enough that you can't force air thru it with by blowing thru the pipe.). As it is lifted up again the marble seals and pushes the water out the top and up the pipe.
I had a 55 gal drum filled with water outside the basement. To test it I only used a 4' stick of pipe. On the 4th or 5th pull up of the threaded rod I got soaked.
Will it pull it up the 50' that I need? I don't know, but judging by the pressure of the water that came out I would have to bet in favor of it. I may have to add some leather gaskets on the outside of the piston to get enough pressure to push it that far, but I'm not sure. It is already a pretty snug fit.
I have the handle and nozzle designed in my head, but before I build that I am going to build one of the old style well covers that looks like you would use a bucket. Right now all we have is one of the fake rocks......no place to mount a pump.
I am going to be sent out of town for work for most of the summer, but I will get it done at some point soon and update this thread.
