    Mini Hydraulic Press

    Welcome. I'm form Poland and my English is not good, sorry for that. The forums in my country don't have a thread about my new idea. So, someone in this forum build his own mini hydraulic press??

    Hi Hans and welcome to this forum. Let me say that your English is a LOT better than my Polish.

    We would need some details on what kind of hydraulic press you mean. Here are some that are available in stores.

    Also, if it help with your English, you could try using this...

    Hi Hans i zapraszamy do tego forum. Chciałbym powiedzieć, że twój angielski jest dużo lepiej niż mój polski.

    Musielibyśmy kilka szczegółów na temat, jakiego rodzaju prasy hydraulicznej masz na myśli. Oto kilka, które są dostępne w sklepach.

    Thanks for the more intrested

    Ok, I thought about the small press (max 20kN).

    Exactly like this one :

    Of course I have a welder, metal and tools. But before I start building, I wanted to ask you about some advice.

    I greet.

    Hi Hans,
    You say you want to build a press "exactly like this one."

    The easiest way to duplicate the design is simply to copy what you see? Reverse engineer it. Go find one in operation somewhere and take your ruler and calipers and a note pad and start measuring. I've always found it to be a little easier if you start with a rough sketch of the unit from different views so that you have a quick simple way to assign dimensions to the features. This way you aren't drawing the unit while you gather dimensions. If you leave a feature out you can always scribble it down while you're measuring the thing.

    If you decide to alter any of the dimensions then you will need to adjust accordingly. If... for example you should decide to make your unit wider... then you would need to add strength to the cross members to allow for the greater distance between supports. Likewise... if you were wanting more tonnage then you would also need to adjust accordingly.

    Good luck!
    Bob

    I don’t know, whenever I see a reproduction of well established products I have to wonder why? Reinvent? - I doubt it...

    If you're building this press just for fun and challenge I understand. If your effort is because your requirements are truly different and an existing product does not fit, again I understand.

    My point is that existing products are already engineered, tooled and are probably more cost effective to purchase than to reinvent.

    All very true guys, but ... most of that can be built from scrap for next to nothing. It doesn't have to be salable quality, but I could build that from stuff around the house for probably 10-bucks in CO2 and power, plus the cost of the bottle jack. Even then I have a bottle jack that came with the truck which I have replaced with a small floor jack, so even that is essentially free.

    I would build it from well casing pipes that came out of my old well. 400+ feet of 3" schedule 40.

    Having said that, I did buy my 25-ton shop press, but that's just because I was lazy.

    In fact, if you had enough scrap lying about you could even build one of these...

    Yeap, and this is the main reason why I do not want buy ready press. Besides, home-made = satisfaction + new skills + experience.

    I greet.
