If you trip over two let me know.I have a long list of people looking
for one.They can fetch good money.I have one sitting waiting on a
leadscrew getting made.I bought it with only three leadscrews and
I`m not sure who actually made them but suspect Churchill.You also see
them branded Tecalemit.
Yes I spoke to Rondean the day I initially posted - they won't budge
on the price, and it's way over budget for me. I've considered making
one - a suitable cylinder is really the only issue as the rest is
basic fabrication. The racking up and down as per the 1551 is a
luxuary, many just use a hand winch.
Rondean seem to be like that. They've Still got the Russian Toolroom
that they had had for a year or more when I was looking for a mill
years ago. Its not got any cheaper, and it still hasnt sold...

Depends on the cylinder/piston diameter and the operating pressure, but I've got
an '8 ton' ram on my Chinese 2 ton engine lift, and a 'proper' ram at home which
is working at 2000 psi on a 2.5" bore by memory, so that's about 4.3 tons and
I'd know which one I'd prefer to use!
The presses use a squat cylinder with fairly large diameter to give the working
West point had a 60 ton Laycock on their advert flyer for some time, see that it
sold for £1750 plus VAT:

I wonder if Govt. surplus would provide a solution, in particular large
bottle jacks used to jack aircraft bogies. I used to use them and IIRC the
one we had for main gears on 767 type aircraft was 60 tons, it was
light(ish) weight alloy and could be held (just) with one hand. We even had
a ''posh'' one with a little pneumatic motor operated pump and a line that
clipped onto the tyre valve - so that air from the wheel being swapped was
used to raise the bogie.
As you say, the rest of a press is just a matter of simple fabrication.
I made a press rather like this
some years ago using a bottle jack.
Fortunately I had a 50T one at work to copy and managed to scrounge
the steel and fasteners for nowt. I used a 30T bottle jack as that's
all I need but the frame will take a lot more. Use the bottle jack the
right way up. If you invert them, the oil port to the pump is above
the oil so it suck air. That is unless you get an all position jack
but they're expensive and not needed for my press. I bought a cheap
new jack for £30. That was the only cost. Use a couple of springs to
return the jack piston and take it's weight. I used garage door
springs. The jack sits on a cross beam that slides inside the
verticals with a socket welded on it's base. This is bored about 30mm
with a side screw to hold a push bar. As the bar's only plain steel, I
can turn the end to whatever diameter I need according to the job.
Also, weld a piece of plate with a hole in it to locate the jack
piston on the top beam and stop it kicking out. If that happens, it
It's not as chunky or as robust as the one you're after but it
certainly works. The only real downsides are the lack of pressure
guage and, being a manual pump, it's quite slow. Well worth £30
