Precision Vacuum Adapter Kits for Jet-1642EVS and Jet-1442 Woodturning Lathes

JT Turning Tools' Precision Vacuum Adapter Kits for the Jet 1642 EVS and Jet 1442 series of wood lathes are designed and manufactured as lathe-specific vacuum solutions to fit these woodturning lathe models.  In service for over two years, the Precision Vacuum Adapter has gained a reputation for high quality and flawless performance with many satisfied users across the country.  See some of our customer's comments about our adapter.

In order to insure the best possible performance for vacuum chucking, there must be a precise fit of the adapter to the lathe.  Due to factory manufacturing tolerances and design considerations, these two lathe models do not lend themselves to the installation of a vacuum adapter directly into the end of the spindle.  Consequently, we manufacture specific Adapter Kits to provide our customers with a high performance vacuum adapter solution for the Jet-1642 and Jet-1442 models.  These kits consist of our proven Precision Vacuum Adapter and a unique hand wheel designed specifically for each model lathe.

Jet-1642

For the Jet 1642, installation is simple: the user loosens the two set screws securing the factory supplied hand wheel, slides the stock wheel off the end of the spindle, replaces it with the hand wheel included in the kit, and re-tightens the two set screws.  For specific details of initial configuration and installation of the Precision Vacuum Adapter, please refer to the Installing your new Precision Vacuum Adapter  located on the Installation Instructions page.  To install the adapter  and switch to vacuum chucking, the user simply inserts the adapter stem into the hand wheel bore on the outboard end, mounts the appropriate vacuum hub and chuck on the spindle nose and you are ready to go.

Jet-1442

For the Jet 1442, the procedure is similar: loosen the two set screws and unscrew the stock hand wheel from the end of the spindle (caution the spindle threads are left hand), thread the new kit-supplied hand wheel on to the lathe and tighten the set screws.  The Jet 1442 hand wheel will be the same length and diameter as the 1642 hand wheel, as this is the most economical choice for production and provides the best value for our customers.  You will have the same size hand wheel as the 1642, which many consider to be a more comfortable and useful hand wheel profile.  This installation will appear nearly identical to the photo below of the hand wheel installation on the Jet 1642.  For specific details of initial configuration and installation of the Precision Vacuum Adapter, please refer to the Installing your new Precision Vacuum Adapter  located on the Installation Instructions page.  To install the adapter  and switch to vacuum chucking, the user simply inserts the adapter stem into the hand wheel bore on the outboard end, mounts the appropriate vacuum hub and chuck on the spindle nose and you are ready to go.

Vacuum Hub and PVC pipe coupling Cups - various sizes available

This provides a low cost, high quality alternative to multiple sizes of individual vacuum chucks, while allowing the user to quickly move from one size cup to another.  The cups (2" PVC pipe couplings) are inserted into the precisely machined groove in the face of the hub, sealed by an O-ring in the bottom of the grove, and retained securely with 6 set screws around the perimeter.  Hubs are available in 1"x8, 1.25"x8, and M33x3.5 spindle thread sizes to accommodate most popular lathes.  Learn more about the Precision Vacuum Hub products on the vacuum hubs page.
