Pneumatic fidget piston

Machined to tight tolerances using diamond tooling

There is a very narrow window where the fit is tight enough to give the pnuematic effect, but loose enough to give the air bearing effect.

A pneumatic fit

A diamond drill makes a perfect hole that creates the air spring effect

Air bearings

Diamond lapping the piston preps the surfaces for a frictionless bearing effect

Brass and Stainless Steel

The brass barrel gives good sliding surface, and the hardended 17-4 stainless steel piston makes it last

Made by hand, in the USA

Each piston is diamond lapped to get the fit just right

Diamond tooling gives the consistent dimensions and surface finishes that this toy demands. The tolerances are super tight, so we incude a cleaning tool and lint free cloths to keep it running smooth.
