Non-Ferrous Pneumatic Cylinder

Non-Ferrous Pneumatic Cylinder

(OP)
Hey guys,

I need a non-ferrous pneumatic cylinder. it doesn't need to be anything fancy, just a basic one, but it can't use any ferrous material at all (no iron, steel, stainless steel, etc.) in any part of it. Any advice?

RE: Non-Ferrous Pneumatic Cylinder

Aluminum.

I can tell you about injuries I have seen involving sensitive body parts and a potato gun made out of PVC. So I wouldn't make it out of PVC.

Engineering is not the science behind building. It is the science behind not building.

RE: Non-Ferrous Pneumatic Cylinder

It's no trick to find brass cylinders in modest sizes.
... all of which have stainless steel rods.

Maybe you can get an 'all brass' cylinder as a special, or buy a mostly brass one, and make a brass rod for yourself.

Rubber airbag actuator?

What's the reason to avoid iron? Kinda curious.

RE: Non-Ferrous Pneumatic Cylinder

Look inside a player piano. Plenty of pneumatic cylinders made of nothing more than wood, leather, and glue.
... plus some skill that may be hard to find.
