A lot of people make their own hydraulic presses. The only manufactured parts you need are a cylinder, a pump, and some I-beams. How do you know it’s strong enough? There’s a saying: anyone can build it strong enough, it takes an engineer to make it just strong enough. In other words, make it look sturdy, when in doubt double the thickness, and it should be fine. Maybe read the specs on the shear strength of a 1-inch (25mm) Grade-8 bolt. (The answer is 41 tons, so assuming this is a 12-ton hydraulic cylinder, there is a nearly 7 times safety margin assuming the load is equally spread between the two bolts. See? No need for a fancy engineering degree for that calculation.)
