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.
