Exactly my thoughts Deegee. I used to overhaul variable displacement hydraulic pumps for Skyhawks aircraft and they had a cylinder to valve head metal to metal seal (4500 psi test press). I had to lap the mating faces to 3 helium light bands of smoothness. QA was with a 40x microscope. That's what made me wonder how they did it.Deegee wrote:Very clever piece of engineering, I'd guess the idea came from axial piston hydraulic pumps and motors - very similar concept, it's a shame they didn't give a bit more detail for some of the problem areas but I guess that would be giving away the farm. Hope they do well with it, although looking at their website & Facewipe acc not a lot seems to have changed for a while.
I know dude. It was clearly jest back I would never really put you in the intelligent camp.kiwikrasher wrote:All in jest mate, you should know by now I don't take anything much to heartBlade wrote:Kiwi come on mate don't be like thatyou were clearly part of the "some"
I put up with the likes of you, so clearly I'm a slow learner!Blade wrote:I know dude.

Come on dude, surely you saw that
Yup I knew it was pretty extreme (22 years ago I was doing that) The lapping plate got sent away for a calibration check every year, but we just checked under a 40x microscope and when the components looked like polished granite you knew it was up to spec.Monty wrote:Had to look that up, 1 is 0.0000116 inches!
