Pump, 3 Chucks w/Adapters & Hardware

This kit is for all lathes with an 1-1/4 x 8TPI spindle, and includes everything you need to get going with vacuum chucking, including three chucks with built in adapters.  Also, there needs to be at least a .4″ or 10mm through hole in the spindle.  Most lathes will have this.

This kit includes assembly instructions, an imported 4CFM pump, the complete hardware kit and three chucks made by Robust from solid 6061 aluminum, fitted with built in adapters, sized: 3.25″, 4.5″ and 6″.  Buying this kit saves you about 5% over purchasing the items individually. 

The built in rotary adapters consist of two precision sealed bearings and a stainless steel hose barb that we also machine.  You will attach a piece of tubing (included) to the barb that will run through the spindle hole of your lathe.  The tube from your vacuum pump will then attach to this tubing.

The polymer seals on the chucks have multiple sealing ridges and are 3D printed.  Each chuck comes with a Tommy-bar for removal.  Some minor assembly required.
