    A couple of questions:

    Would a pair of coil spring compressor clamps across the flanges help stop the spreading? Advantage may be that they are movable and could be put on only when serious grunt is required.

    With electronic stuff being cheaper by the day, is an electronic load cell an economic possibility? A lot of 8-wheel muck away tippers have them on now, and almost every tarmac lorry.

    I think id like it not to bend to start with and I wouldnt press dirctly onto the table flanges anyway but its an idea

    so the load cell would have to go on end of ram ?

    Id like mine powered too , i have loads of pumps but a 240v all in one unit would be ideal. I also have a 30ton air over hydraulic jack but not sure if I can separate the pump unit

    What size pins / material did you use? It’s what I’m stumped on with mine but it’ll only press 20t

    In another thread i put up a link to parts diagram for one of the air-over jacks, looks like the "air motor" just duplicates the piston action in the manual pump (valvery in the jack base), so it should be possible to unscrew the air motor, put a piece of hydraulic hose with the right threaded ends between the two?
    I'm planning to buy one in the next few weeks and find out... Assume it will need a remote ol reservoir plumbing to the pump pick-up, or a (floppy silicone, weighted?) tube to reach the was-top-now-bottom of the existing reservoir?

    There are some good Youtubes on inverting / "upside down" hydraulic jacks, lots of detail - mostly fitting a tube to the port in the bottom of the outer reservoir so the pump picks up oil, and putting a remote reservoir to a fitting replacing the rubber/plastic filler bung.
    Looking at the position of the air motor/pump on that, you could probably get away with leaving it where it is?

    Are you going to hang on to it? If not, I might be interested if it's not too spendy nor too far away (I'm close to the Surrey/Hampshire border)... how fat is the outer reservoir? - I've already committed to the materials for my press-to-be frame!

    That’s gauge is going to have no bearing on the tonnage of your ram if you’re not using the ram it was specified for.
