Hi Hank,

Have a look for some steel NGV (natural gas Vehicle) or CNG  cylinders.  They are rated for 3000 psi generally and there are bound to be some at some scrappy’s yard.  If you can get a 70 litre or such then chop off the top and weld a couple of plates on.  They are at least 10” inside diameter.  I have a couple marked for test chambers.  Good for at least 5000 ft depth test pressure.  Hugh

Nice thing about big hydraulic cylinders, they are cheap because they are impractical for most things.

I think I will add electric penetrators so I can test thrusters while they are running.

Good improvisation Hank,

would not have thought of using a hydraulic cylinder.

Will keep an eye out for one.

Today I had some time to kill, so I built a pressure chamber big enough to fit a thruster.  I can fit 6 by 20 inches up to 2,000 psi.  The chamber was a hydraulic cylinder from a crane and is surprisingly  light.  Next time I have my pressure washer running I will wash it and paint it up nice.  I just have to un-screw the top to open it up.
