JonDoh Posted February 8, 2017 Share Posted February 8, 2017 Hi all, Quick question, I can get hold of a full working set (cheap) of hydraulics from a large delivery vans tail lift, not the weedy little ones, the type you wheel a pallet on to. Any good for a small forge press? I don't do massive billets of pattern welded steel and only have the tinyest of workshops, but would like to reduce some of my anvil time to appease neighbors noise wise.

BIGGUNDOCTOR Posted February 8, 2017 Share Posted February 8, 2017 For a forging press you need speed as well as power. Those have the power, but may not be fast enough. You need to figure the volume of the ram, and the displacement of the pump is usually listed as GPM-gallons per minute. That will give you the ram speed. There are a few threads covering this.

Frosty Posted February 8, 2017 Share Posted February 8, 2017 On the safety side. How much do YOU know about hydraulics? There are much safer things to mess around with, a pinhole leak can do pretty nightmarish things to you some you won't even notice till your internal organs start shutting down. About your question, it CAN be done just be VERY careful. There are more things can go wrong with a home built hydraulic tools than can be listed in a couple pages here. How good a welder are you? That's just item two of a long list. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
the iron dwarf Posted February 8, 2017 Share Posted February 8, 2017 call in, im local and make presses, you can see possibly the worlds smallest forging press in use if you want. Quote Link to comment Share on other sites More sharing options...
the iron dwarf Posted February 8, 2017 Share Posted February 8, 2017 if it is off a delivery van it will be weedy, something off a 30 tonner may be stronger but they are slow and you need speed also you will need a 24 volt dc supply rated at least at 50 amps continuous ( not a 50 amp battery charger as these are mostly exaggerating their output, start and charge units are only good for a minute or so ). have you welded things like this before that are made to take this sort of repeated load, my first press was probably made early in the 1980s and I sold it in good working order a year or so ago after using it for thousands of operations some weeks Quote Link to comment Share on other sites More sharing options...
JonDoh Posted February 8, 2017 Author Share Posted February 8, 2017 Thanks for the replies, In answer to the safety questions, not enough and terrible Really I am asking as I can get the hardware cheap "right now", its a long term plan for me, I'm not a must have it right now person and I certainly wouldn't weld it myself. Being a hobby guy with not much money I have learnt that making a plan, then waiting for the right pieces to fall into place nets me the best results. Mr Dwarf, I will take you up on that some day, we did speak before about making me a hood but I found a friend of a friend to do it for beer money, though they are not the kind of welder I would ask to take this job on.

the iron dwarf Posted February 8, 2017 Share Posted February 8, 2017 I now make hoods for make hoods for my forges, yes come over and I can tell you more about what you need and you can see mine in use Quote Link to comment Share on other sites More sharing options...
JonDoh Posted February 8, 2017 Author Share Posted February 8, 2017 No its 12v so I'm guessing far too wimpy, are you ever about weekends, being a 9-5er I don't get out much Quote Link to comment Share on other sites More sharing options...
BIGGUNDOCTOR Posted February 8, 2017 Share Posted February 8, 2017 The voltage does not matter, but it will pull a bunch of amps. Quote Link to comment Share on other sites More sharing options...
the iron dwarf Posted February 8, 2017 Share Posted February 8, 2017 the voltage will matter if you put 240v through it and if it is a 12v one it will be more like 100 amps needed Quote Link to comment Share on other sites More sharing options...
