Sounds like it will never be cheap enough for you.

People want money for materials and labour.

Repro glass cylinders are cheap, around 300.00 real ones usually 400-800 except the rare ones like for the double pumps, they can run up to 1000.00 or more for 1 cylinder.

Your best bet, get a pump missing a cylinder and run hail screens.

To try to build one on the cheap, usually looks just that..cheap.
A lot of time and effort expended to build something very few people want, and will you really be happy with it?

Cheap globes are 70.00 , that is very cheap compared to real ones!!


Here is what 500 would bring in the repro market.. about 1- 12 hrs labour but you must deduct parts, material, paint, hose nozzle etc from that leaving even less for labour!


Good Luck on your hunt...
