Oneway Rotary Air Fitting
The Rotary Air Fitting makes the connection between your vacuum pump and your lathe spindle/drum chuck. It mounts to the outboard side of your lathe spindle using a Oneway Stronghold-type Mounting Adapter and maintains the air connection between the pump and the chuck while the spindle is turning.
Vacuum chucking is a productive turner’s dream of instant, positive, non-marring holding power and instant release of the work at the flip of a lever. If your headstock spindle is through-bored with no cross holes, and is threaded at the outboard end, then you’re ready to mount a vacuum chuck.
You’ll need six components to complete the system: a Drum Chuck, a Rotary Air Fitting , a Vacuum Gauge Kit , a Vacuum Pump , and two Stronghold Mounting Adapters (one for your inboard spindle nose, the other outboard.)
