Hydroforming the Albion Way

This is part of the BCVP project that has been undertaken by the Albion team for the last three years.

The problem was how to produce a 180 degre bend in the home workshop cheaply.

Nick Ibbitson cracked this one and did it in a style that has to be admired.

The high pressure water pump is home made from a drill stand, two sheets of steel are cut to shape and then welded along the seams, the water nipple is attached to one sheet.

There is no danger as there is no air in the system although high pressures are generated if there is a leek the pressure is gone almost instantly.

Impressive!

Thanks for the graphics, Viv. I had no idea those little drill pumps created enough pressure to mold the metal that way. What guage is that steel?

a quick note here, mike k, sup with your msn bud?

I dunno. Every time I try to log on it takes me like five or six tries so I've just given up. The dog is all the company I really need.

No Mike it is a drill stand as an anchor for the arm that pushes down on the plunger in the pump doby at the bottom it is not a "drill pump" that runs off a drill.

Gauge? I cant remember but about 1mm I think

Any ideas on what kind of pump they were using?
Or what could be used, standard brakeparts may be a bit on the weak side.

I thought a checkvalve would be needed but after some brainstorming with my brother i think not.
As long as the sheetmetal can give after there will not be much backflow.
That make a brake main cylinder a possible candidate.
But still it would be interesting to know what pump was used.

As far as I know it was a simple plunger type pump and he knocked it up in a spare moment!

Why dont you give him an email? nicks address should be on his profile.

I have made various test pumps using plumbing fittings but the fastest one to build was a grease gun plunger pump assembly with 2 check valves from hydralics place screwed in to the bsp fittings (bit lucky there) I've used it to cold hydro pressure test steam stuff to 800psi (tee in line for a cheap gauge).

Yes, i guessed it was a simple plunger type pump, what occupied my thougts was if it was with a tight fitting piston or rubber seals.
Maybe i drop him a line later, this is still just a mindgame but i have this obsession to have some experience of all useful trix i come across.
You know, its just a matter of time nÂ´til things like this comes to good use.

Are there more links like these? Are there people on this forum who have experience with hydroforming like this? What would be the maximum plate thickness using stainless(316) steel and using a pump that reaches 2.5 bar.
I think this method will give better results if used for bigger diameters.

That was a most enlightning link!
I had more or less figured out most of it by now, but a step by step description of a real-world project is quite valuable as a "motivationbooster" .
Today i found the tragic remnants of a hydraulic car jack in the trunk of my car (cant remember where it came from, but it must have looked useful i guess) itÂ´s to rusted in the working cylider to be a candidate for my soon-to-be hydraulic press but the rest seems to be custommade for me and my ideas about hydroforming;-)

I cant help thinking, there really should be some kind of archive where this kind of useful links could be stored!
It would save a lot of time and effort searcing for some link one know there was somewhere in some thread, but where.
That if something can really ruin my day when i dont find some url i just know is there but obviously is forever lost....
