I already know everybody says its cheaper to buy one than piece one together. I'm fortunate in my job as purchasing agent for a mining company I have a lot of connections. I started out with an old cylinder sent to our hydraulic repair company to be rebuilt. Well it was beyond repair, sat out in the weather for too long. So he calls and asks what it was going to be for , I tell him a splitter. He calls back and said he had one on the way no charge. I ended up with a new cylinder with a 30" barrel around 5" in diameter. So I'm thinking a 16 GPM two stage pump. Next I sent a couple of old pto pumps from equipment we no longer have, to trade for one I could use. He sent me a brand new Bailey 16 GPM two stage pump. This pump is rated at 3000 PSI at 3600RPM. Well I already got a control valve when we switched all our grease trucks from hydraulic to air operated. The one thing major component I'll have to buy is a motor. The metal will be no problem as I get everything from our suppliers at a big discount or for nothing. Hoses are no problem either, I have a hose machine 30' from my office. Whats everybodys take on a motor. Looking at the specs on the pump it call for a 8 HP. Anything I'm missing. I can weld everything up myself. I'd like to find some plans on the hydraulic circuit. I have a background in electronics, and I'm certified mine electrician, it's easier for me to see how to put it together from a diagram or schematic. Any help would be appreciated from someone who's done this before.
