How to make a hydraulic manual pump for hydraulic press machine 100ton?
i have made a hydraulic press machine of nearly 100 ton capacity, but i have not be able to make the pump for the press machine, will anybody help me thank u

Buy a 100 ton bottle jack? Buy 4 25 ton bottle jacks? It would seem likely that minimal leakage would be necessary with a small pump cylinder, a pretty strong valve, and a big pushing cylinder and lots and lots of pumping. What part is failing for you?

How do hydraulic rams produce so much pressure?
I've been around hydraulic presses, benders, etc. plus I notice how heavy equipment works. These things work at around 70-100 tons psi. how do those tiny rubber hoses work? Is it made in stages?

Any ideas on a DIY die press for 2" soft foam cutouts?
I want to die cut 2" medium density polyurethane foam. I am not a die maker, but I do weld and am able to cut and weld together the shapes that I want. I use 16 gauge steel which is sharpened, shaped, welded, and then touched up to be sure it's true and flat. This process isn't 100% accurate, but it will be good enough for my needs. I built a hydraulic press using 1" square tubing, and creating a 20" x 20" x 20" cube, with a fixed floor and moving ceiling. I used a 6 ton bottle jack to provide pressure. However, even with around 4 tons of pressure, the 2" foam (which is probably less than 1/32" thick when compressed) will not cut reliably. Parts of it will cut well, but others won't cut at all. If I take a hammer and hit my die, it will cut through all the way as I tap along the outside of my die, but the walls of the cutouts aren't very straight since the whole piece of foam isn't compressed at the same time - only the exact point of contact with the die is flattened. I hope that makes enough sense. If anyone out there knows a thing or two about die cutting, I'd appreciate any ideas! I'll check back and provide more detail if anyone has any follow-up questions.

I know just enough about die cutting to be dangerous. That's because I built a homemade die-cutting press that cuts 1000 piece jigsaw puzzles. And that's not easy! Commercial dies are made using something called Steel Rule, and it's pressed into very thin grooves cut into a sheet of plywood. Also, there's usually some kind of foam on top to act as "ejection rubber". It takes a lot more force than you would think to cut something with a die. I think your steel is too thick to cut easy. And, you probably need some ejection rubber. What you want to happen is, when your die presses down, you want it to go past the material you're cutting, and below it a little bit, and then after the die is released, you want the piece you cut to "pop up". Also, a "cutting pad" is used, to protect your blades from being damaged. For this, I've used a type of plastic that fabric stores sell for quilters to cut on with a razor knife, they sell a green laminated sort, and a thicker, milky colored one, and it has lines drawn on it. That's the kind I've used. I cut into suitable size pieces. I don't know if this makes any sense, and this is a complicated subject. You can email me at homesteadpower@hotmail.com if you need more help on this. EDIT: After re-reading this, I'm going to take another stab at telling you how I would do this. Place your steel die on your fixed floor, facing up. Fill this die with tough rubber for ejection rubber, I get mine from Monroe Rubber. It comes in different densities, you will have to experiment to find just the right amount of density and quantity - this is a major part of the skill. Place the 2" foam you want to cut on top of the die. Put a cutting pad on top of that. Put your hydraulic jack on top of that, and jack away. Only your hard plastic cutting pad contacts the steel cutters, you don't want your jack or any other steel surface to hit it too, or the blade will dull immediately. The object is to press your 2" foam down into your die a tiny fraction of an inch, and then when your jack is released, you want your cut circle to pop up. There, is that clear? The cutting pad is considered disposable, although you get a lot of cuts out of each one. Each time you press down with your jack you'll press a little groove in the cutting pad, and each time you use the cutting pad for a new cut, you move it just a hair, so the grooves get cut into a slightly different place. After it's all cut up and distorted from being used on both sides, you throw it away and use another chunk. Mind you, there's probably a lot faster methods for fast production guys. I'm telling you how I do this on a one-at-a-time very small scale. I don't use a hydraulic jack, I use what is called a "roller die cutting press", which is two motorized rollers, sort of like a giant wringer washing machine. You can adjust the gap of the rollers very precisely, which is important, at least in my application, so that it cuts evenly all the way across at the same depth. But that's a lot more important to me, since I'm cutting 19" wide at a time.

Is it a good system where a pilot travelling as a passenger spots a fault that the real pilot can not see?
Qantas A380 incident far more serious than originally reported by Charlie Leocha on December 3, 2010 It appears from various press reports that the emergency landing of Qantas A380 Flight # QF32 was far more serious than the initial press reports. The engine explosion was monitored by the cockpit, but an alert off-duty pilot spotted additional problems being broadcast from a tail-mounted camera. That was the beginning of a string of failures, however the pilot and crew managed to land the plane safely. Pilots of a crippled Qantas Airbus A380 superjumbo struggled with more than a dozen system errors after an engine blew apart on November 4 and landed the plane in Singapore with barely any runway to spare, an Australian investigation showed. In fact, the plane may have been so badly damaged that the five pilots, with a combined 72,000 hours of flying experience, may have saved the day. As crew moved through the plane to assure passengers that all would be well, they were alerted to the video playing through the onboard entertainment system from a camera in the tail of the plane. But while several system warnings went off in the cockpit, the fuel leak was only spotted when a Qantas pilot, traveling as a passenger, saw the trail in an image broadcast from a camera mounted on the plane. The picture showed the Airbus was leaving a trail of fluid behind — most likely fuel and perhaps hydraulic fluid — from a puncture through the wing. As the plane lost fuel quickly, its centre of gravity also started to shift, presenting another problem. But the crew could not move fuel as required as it was not clear how badly the fuel system was damaged, the report said. Meanwhile, the veteran pilot was going through the plane’s checklist to find out what his real situation was at altitude and what his alternatives were to land the aircraft. Captain de Crespigny, a veteran of 35 years, was commanding a giant of cutting-edge technology that started flying commercially only three years ago: his aircraft, with more than 8000 hours in the air, entered service in September 2008 as Qantas’ first A380. Shutting down the damaged engine, Captain de Crespigny broadcast a PAN-PAN alert – warning of urgency rather than the imminent danger of a Mayday – asked for a priority landing and, with the jet trailing smoke, circled Singapore dumping fuel and preparing to land. The problems were just beginning. Fuel couldn’t be dumped because of weight and balance issues and the super-jumbo jet weight was calculated to be within the stopping distance required at Singapore, just barely. Plus, onboard controls had been damaged by the engine explosion. With the plane coming in at 440 tons, about 50 tons heavier than its maximum landing weight, the computer eventually concluded it would stop with just 100 meters of runway to spare at Singapore’s Changi Airport, the report said. But 100 meters was enough for the crew and they opted to land instead of dumping fuel, which would further upset the plane’s balance. The A380 “remained controllable” as its prepared to land, but it lost many of its systems which controlled pitch, speed and braking, so pilots asked the cabin crew to prepare for an emergency evacuation as they risked a runway overrun, it said. The Airbus stopped with just 150 metres of concrete left, brakes heated to 900 degrees Celsius and four blown tires. But the problems didn’t end there. After deciding not to evacuate the passengers, the outer engine on the same wing as the damaged engine refused to shut down. “It was gushing fuel and one of its engines refused to shut down for over two hours, until fire crews drowned it with foam.” The investigation and following court cases will proceed. However, this was an emergency landing where, overall, everything went well and the crew responded expertly. Looking back on the situation is clearly scarier than it seemed when the super-jumbo landed.

This was known to have been a very serious failure by those in the industry from the moment the aircraft landed and crews took a look at it. Uncontained engine failures such as this one are always extremely serious incidents. The press knows nothing about aviation, so its reports don't matter.
