    As promised in another thread, Pictures of the simple press I made to take a 10T ram like you have. As I said, I turned and screwcut a holder for the ram

    thats a good job, exactly the same design as my big press, you are putting the load on the threads in the ram the the plate and not in a weld (if the plate was on the top of the channels)

    @Ton-up That's brilliant!! Thanks for doing those. :hug:

    I was looking to have it easily stored, so I've been scratching my head on how best to 'fix' the ram to the frame. I was thinking of having the top rail U section welded to the two uprights with the open end up, then drilling through to accommodate the ram after getting threaded holes done in 2 x flat, rectangular plate for either side of the top rail. Typically, overthinking things again......:doh:

    Your round 'ram locator' looks very thick, I suspect the 'skip find' plate(s) I have are 5mm [like the U channel I bought] - does the Collective think that would be robust enough? :dontknow: Also, drilling for and cutting the 13 tpi thread will be problematical for me as I've not 'graduated' to screw cutting on the Myford yet......:ashamed:

    Your design looks much better than mine, so I'll copy that - unless you have a Patent on it....:whistle: :D

    Thanks again! :thumbup:

    It's as thick as the threads on the ram. 5 mm will never be thick enough, you will deform the threads I'm afraid.

    Could you not find a spare screw-on end for your ram & use that? I'm guessing you're using one of the ram/pump units used in porta-power body straighteners & the ends are available to buy separately. One of my planned projects is a bearing press & I'm using the ram from my porta power & a spare screw on end.

    I vaguely remember a post on here about using a cheap Jack converted to work upside down. Maybe a cheap option instead of buying/modifications to a porta power?

    To be honest its not really worth making one, by the time you buy the hydraulic pack, cut and weld the steel girders its quite a lot of faffing about. I would look for decent 2nd hand units or new chinese 10-20 tonne jobbies, some are decent and last a long time too... Good effort though...

    I’ve done it few times and spent too much a few times!
    But it’s a useful project to make if you want to make something.

    You mean the round, threaded bit? I suppose I could get a bit that's thicker (or weld 2x bits together).

    That features in the plan too. :thumbup:

    Maybe not now, but I made this over 25 years ago when things were more expensive and I was on apprentice wages. You didn't get cheap Chinese made stuff on ebay!!

    Without doing any maths I’d say you’d need at least a 12mm plate for the cylinder mount

    I'll have a hunt in the 'bits' bin tomorrow, I may just have something that thick.

    There still remains the drilling and internal thread-cutting, both of which will be beyond me. :ashamed:

    I'm more than happy to pay someone who can duplicate @Ton-up's ram securing setup for me?
