Oneway Vacuum Gauge Kit

When vacuum chucking, it is critical to maintain sufficient vacuum. The

Vacuum Gauge Kit

helps you do that. It fits in your vacuum
piping between the vacuum pump and the rotary air fitting. It has a bleader valve and a gauge that reads pressure in inches of Mercury and Bar.

It’s best to check the gauge periodically to make sure you have appropriate vacuum. You’ll want to keep at least 20 inHg of vacuum
(~0.65 Bar) to hold most pieces securely. More vacuum will hold better, but don’t use too much or you might collapse your bowl.

The Vacuum Gauge Kit includes everything you need including: a vacuum gauge, mounting bracket, bleeder Valve,
5 feet of 3/8″ reinforced PVC hose, hardware pack and instructions.

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,

two Stronghold Mounting Adapters

(one for your inboard spindle nose, the other outboard.)
