The hose coming off of the vickers pump is not the high pressure hose I have other hoses that go to the otc 10,000 psi pump. I use the 5hp vickers pump for everything,I have found it to be more than adequate for anything I could ever want to do. The cylinder is 8 inches in diameter that thing that is on the end is a nose I machined up so I can change out tooling. The pins are 4130 2.5 inches around they probably are a little small. I have taken the press to 90 tons to punch 1 inch steel holes through 3/4 plate and had no problems but I have never tried to max it out. I dont have any experience with hydraulics this is my first project that used them I looked at alot of big presses and tried to copy them. I got the ram from a scrap yard it was bent so I cut it down and rewelded it to 13 inches roughly. Getting through the hard chrome is a killer I have a big power hacksaw and it took an hour I even ground away the area I was going to cut with an angle grinder. I spent about a year on and off building it the guys at the hydraulic shop were real helpful but at first they were saying if you are asking these kinda questions maybe you shouldnt be building this. Building it definitly maxed out my shop just moving the steel around and getting it up on the mill to drill it was a pain I cut all the stock on my power hacksaw and after doing that I went and got a bandsaw. I have built quite few machines for my shop I have a pneumatic forging hammer and an air planishing hammer, I built a pyramid roll with a 7.5 hp motor that I sold to a shop I thought I wanted to get into the metal fabrication bussiness but their is so much competition from every guy with a buzz box and a chop saw. I still have not figured out how to introduce myself I will get my wife to show me how to do some more stuff on here. thank Kevin
