    So, where do you guys go to source hydraulic parts? I'm designing an electric over hydraulic tube bender running a 15ton ram. Plan to mostly bend .120 x 1.75" dom tubing. I have my specs figured out (thanks to sft) and now I just need to find the parts and buy them as money allows. I was thinking surpluscenter for the ram (4"x18"x1.5") and valve (2500psi), but what about the motor and pump? I figured going local for the hoses. I would love to find a pump that would run 2000psi minimum and .15ci/rev and run on a 115v/20amp circuit, but i can certainly handle running the pump on 230v. I only have one 230v circuit available, so I get tired of swapping the plugs for each machine out of the receptacle. I hope this all makes sense to someone...

    Also, I am using a spreadsheet for all these calculations. I plan to build a reservoir. I have a sheet of 14ga just sitting around right now. I only need 1/2 of it or less to build a tongue toolbox for a trailer.

    Ok Elvis this is kind of difficult because this is going to be a location thing for you. Your going to need a couple of things. Ok for me I live near Detroit MI so I go to a couple different shops one for cylinders and hoses and the other sells and repairs motors, pumps, and valves. When I need something they walk me through it with all the parts and accessories I need for hydraulic applications. I recommend finding heavy equipment places around you then ask them where they get their hydronic motors rebuilt and go from there or search for places near you. I will get the number at work for my place and can give it to you or make some calls for you. It should be that difficult.

    I get most of mine from surplus center. I have also purchased parts from www.daltonhydraulic.com

    If you have a compressor in your shop, have you considered air over hydraulic? Way cheaper than buying a hydro pump and setup, and works just as well.

    That is what I have now. I'm looking for faster cycle times. For an 8-ton air/hyd 20" stroke ram to go full cycle takes almost 2 minutes. I'm looking to cut that down to 40 seconds or so. Also, When I build a shop press I can push a little more force out (40ton) and also run the ram on a trolly so I'm not stuck in only one position.
