Thread: 55t press

yep I know what you mean now. Something to think about for sure. Some have a large wheel that you spin, kind like a submarine hatch door handle. Already onto the winch for the adjustable deck. What would have been better would be a double acting cylinder so I could attach the deck to it and raise with that

Although I dont think it the better way, Im thinking Im going to need to bolt the head to the uprights and the uprights to the base. Otherwise it will be one heavy bugger to move if needed....

well after doing a bit of searching, maybe bolting together is the better way.....

DAVE PROPST ARTICLES - H-Frame Hydraulic Press

well worth the read. Very VERY nice press. Id be happy to get Dave to work on a car simply going by the job he did on his press

Unfortunately I dont have the skills or machinary to achive the same press, but I hope some of the concepts should help me. It will be a matter of making it as accurate as I can...gulp!

Wow, that thing is a work of art! There are some very good ideas that could be used - looking forward to how yours comes together.

yeah tell me about it Dave's is awesome. So glad guys like him take the time to share their work and ideas. Mine wont hold a candle to his but if its 1/50th of the quality and doesnt fail ill be happy. Im only sorry I didnt find his before I started. I had it in mind just to do the standard, but then started to think " this thing is going to weight a freaking ton/ne, how the bloody hell will I assemble and move it............which lead me to think bolts, the search pictures on the web and then found Dave's....

My ram wont be height adjustable, and with over 13 inch of stroke it wont really need to be. I still want it to tram left and right. I really like the idea of less welding. Though I enjoy welding, I strugle with weld distortion and welding heavy section is always going to have the risk. I pro welder I am not.

I just have to figure how to get accurate with my layout....I dont have a mill with digital readout for indexing holes....just a tapemeasure, square, verneers and scribe....

When I first thought about a press I was using a mates. He has built all his own including the rams, pumps etc. I asked him for advice and he said that working on LR's he had maxed out his 30t a few times and had to use his 100t. So I looked for a 30t ram but could only find 20 and 50/55t ..... A good quality 50t H frame press wasnt cheap then either, but now you can get an ok Chinese type for about $1000. I have WAY more into mine than that. A $$$ leason, but atleast I get some experience making something. I really wanted to do the lathe work, but the only lathe I have access to that would swing the 50mm plate is 1000km away.

Edit: I forgot, I also bought the hand pump from the USA, also a SPX Power Team, but I got it from Ohio Power Tool. They were happy to ship to me. Pretty easy to deal with as well. I still get emails with there sales etc

G'day mate. Started following your build here and can't wait to see the finished product! Since you started, I've also started toying with the idea of buying a press. Where did you see the cheaper Chinese types?

I can't see myself using it very often - just the occasional LR thing so thinking a cheap one might do the trick. Although still haven't decided if I need a 30 or 50....

Well dont expect to much to happen to quick guys. I will be winging this one and having to solve problems as they come up....new ground for me.

Judo, check out the link below, just a few examples.

Hydraulic Press - Manual | machineryhouse.com.au

can anyone tell me from a structural stand point, how much material should be left around the outside of a threaded hole. Is there a ratio based on dia or such? I pick up my 100x16 and 75x12 flat bar tomorrow. Dave used 3/8 in his 3/4 and Im thinking this to tight on 16mm, so may go down to a 5/16.

Your thread has come up at just the right time for me, I am currently collecting all the bits I need for constructing a 30 ton press and now I might even up my ideas to 50 ton !

Thanks anyway, I will be following this thread closely now and that article on Dave's press has me thinking also.
