Well, I've wanted a shop press for a while, and after they took the full skip away this week, pickings looked slim until contractors dumped some junk...
A Fenner hydraulic power pack, 1 HP 240v motor, the pressure switch is labelled for 2000 psi but appears to be adjustable (risky?), electrical shuttle valve for ram in and out (assuming double-acting)... There's a quick-release hydraulic outlet on it too, and it all seems to work (haven't yet found the right adaptor to put a pressure gauge on the output hose - there were a couple of gauges, too!)

Some Useful channel, four pieces 135x35mm with 5mm web (approx 5" x 1-3/4" x 3/16" in real money), 1m45 (56") each, and some Sturdy Steel Angle (almost 2.4m, 96") to make the feet for stability and tie the uprights together...
[attachment=10969][attachment=10970]
OK, so Those Who Know - assuming a single piece of the channel for the uprights, 20mm bars to sit a pair of 28" long channels (bolted together with sturdy welded-in spacers) on for the moving table, pair the same size bolted and welded for the top of the frame, what's a reasonably safe max tonnage for the frame? With a 11 square-inch ram it should give 10 tons, my back-of-a-fag-packet calculations suggest it'd move at about 1mm/second (25 seconds per inch), am I way off? Is it feasible to set up two rams (to allow for the narrow gap between the top rails) with an equaliiser bar to share the load between?
I also got (last week) the frame for a new bench, 100" x 44", that's up in the garage-of-danger now topped with 3/4" hardwood ply, followed by a pair of 36" square x 3" deep steel drawers complete with ball-bearing slides, need to bracketise them to fit under the Big Bench. Which is already covered in junk in need of sorting and storing. :( This week, a smaller 1" box-section bench frame, only 24" x 60", which needs plates welded to the legs for castors and a 1" MDF top (castors from AldoLidl, bless 'em, MDF also scrounged today!)
Yes, I know, several Lovelaces of suckage...
Cheers all,
Dave H. (the other one)

looks like standard JIC fittings on the pump.
Speed is going to depend on what the pump is designed to flow.

Yeah, I know, I know...
Donation from the bulletiin board at work - I missed quite a bit of more general metrology kit, was too busy on the day it was posted (damn customers, it'd be a brilliant job without 'em...), but at least I didn't have to dive in the skip for it!

Left to right, top to bottom, a nice cast iron box square, Mercer sheet measurement clock, 0-2" bench micrometer, set of metric Mitutoyo micrometer bore gauges, BIG Moore and Wright bore gauge , another, set of smaller Mitutoyo micrometer bore gauges, metric and imperial micrometer heads for the 2" bench micrometer, 1/2 thou" and 0,05mm dial indicators, 25-800mm bore micrometer kit...
I wish I'd seen it earlier, there was a full set of lab' grade gauge blocks in Imperial sizes... I''d have killed for those!
