I like that. How did you print the chart?
Sprayed a square of PET-G plastic black, laser etched the reverse image to remove unwanted paint, over sprayed the lot in orange, reversed it and screwed it on!
Details and pictures here:
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.
these are the press plates 50t
so you need something on the range of there thickness
I like that idea , I have some 30mm plate i could make into that setup but it might be armour plate i need to try drilling it first
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 ?
there is others out there
i managed to get 1 1/2" thick plates for mine the recent buy gave me 2" thick if i wanted
Cheers Gaz i'll look into that , my main issue is cutting think plate at the mo as used to get O2 for my gas axe from a mate but cant now and I dont want to get it on contract as I dont use it much
I made my press table from 25mm flat.
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
Hobby weld do rent free gas.
think they all do to be fair
What size pins / material did you use? It’s what I’m stumped on with mine but it’ll only press 20t
This is my 40 ton press being assembled...
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?

I found this one ive had for a while i think its 30ton i was going to use it as the basis for my press until the cheap complete one came up
im wondering if i could use it some how
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!

I'll have a think about it Dave i have a few other ideas for it but if I dont do it you have first shout
ok some nice pressies arrived today
going to be for table lift some how , ive seen them attached to table or press i'll see what other people have done in interweb
its not 30ton but close enough and was £25 from Ebay the threads look the same too if im lucky
just the adapter was over £50 new
will see if it fits later
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.
