I can't decide what to build first, but I'm still not done with the CAD for my grinder so I'll start on my Hydraulic Press/Forge.

I got a smoking deal on a used hydraulic system on craigslist for $300. It was originally used in a conveyor system to move cars. 7.5HP motor, 16 GPM pump came with a flow control for speed and pressure regulator and a 30 gallon reservoir. Massive overkill as far as power, but I put it on a moving dolly and it'll be my portable power pack if I ever need to use the system somewhere else for something. I'll post a pic tomorrow. The power pack will be self contained and the only thing connecting it to my press are 2 hydraulic hoses with quick disconnects and a limit switch. To the power pack I've added a solenoid valve so I can control the hydraulics with a foot pedal. When you press on the pedal it'll lower the ram when you lift off it'll automatically go up. The limit switch is to set the return height of the ram. You'll use a thumbscrew to set the limit switch height depending on how thick a piece you're working on.

I'm way OCD especially when designing equipment so I think I've bundled all I can into my press. The bottom die is removable and can be set at different height in case I ever need to press a bearing into something tall, why not make it a little universal I'm spending enough money and time on it. It'll also be on casters.

Here's my CAD minus the adjustable limit switch and casters.

Overall, a good H-press (not a forge). The areas I would take a second look at are the size of the uprights and the movable lower die support. The lower support cross beam is the one that takes the most force in the press. I think unless it is welded heavily and braced from the bottom it may move or bend under 20-30 tons of pressure.
 
So I changed the design based on what I feel like...HAAA. I went with 6" x 3" Steel tubing 1/4" wall instead of the I-Beam. Cost as well as the center web of I-Beam isn't usually that thick, around 1/4" and both sides teeter on that center web. The tube is going to be stronger.

Tig welded the frame and put on the wheels. Got the hydraulic system all buttoned up. It has a pressure regulator, flow regulator, electric solenoid to control the up and down with a foot pedal. Also a limit switch for the upper limit so when I'm pressing it won't go all the way up. It will go to a spot I set so I'm not waiting for it to come down.
