Hello, @1CJK! It's a shame I got to learn about this site almost 4 years later after your post... I've been searching on how to build a hydraulic press to emboss leather with a customized brass stamp I ordered from AliExpress (1.1/2" x 2.1/2") and the main issue bugging me is how to get the movable plate (at the bottom of the jack) parallel to the base plate. Most designs use a guide on the frame, but it ends up swinging a lot. In you project you used a kind of guide on the internal frame. Is there some king of bearing inside? Could you please share any additional information on how it works and/or how you built this part? Thanks and congrats on your project. It's amazing!
