    Vacuum Chuck Adapter

    What's the best vacuum chuck adapter for a Jet 14-42? I'm about to purchase the Precision Machine version (woodturnerscatalog.com) but the size options only list the Jet 12-36.

    Ask ahead of time to make sure it'll work.

    But I'd just make one. It's round! And pretty straightforward turning. All you need is a bearing and a nipple.

    they are pretty easy to make, but if you're going to buy one, check out JT Turning Tools. They work great - never a leak.

    JT wants $160 for the 14-42 version that threads onto the end of the shaft. By "easy to make" I'm assuming you mean the type with o-rings that slips into the handwheel. I'm not sure what to use for the bearing housing.

    I'm surprised there aren't more Jet lathe owners who use vacuum chucks. I expected more responses.

    I use the threaded rod system the hold fast sells on my 1642 Jet. Works great for the past 4 years

    I don't know about the 1442 but the 1642 apparently had a problem with the handwheel design such that the type of adapter with o-ring seals didn't work. JT Turning tools offered a replacement hand wheel with a vacuum adapter for the 1642 but it was expensive. Lots of people went with the hollow threaded rod type. I planned to machine a new hand wheel for my 1642 but then got a PM5320b and two different Oneway vacuum adapters. The first one required removing the hand wheel each time I wanted to use a vacuum chuck - a significant inconvenience. The second is a rotary adapter with the o-ring seals which simply slips into the hand wheel - much better!

    I bought the bearings and parts to build a rotary adapter from scratch. I plan to machine a housing for the from aluminum but construction can be simpler than that. I can imagine turning a piece from lignum vitae that would hold the o-rings and adapt to the bearing. Also, Joe Woodworker has instructions and parts for a design that could be adapted to fit many lathes, perhaps the 1442 (depending on the hand wheel design): https://www.joewoodworker.com/veneer...umchucking.htm

    If you haven't see Joe's web site he has a lot of good info on building vacuum chucks, etc as well as a more complex vacuum system suitable for vacuum bagging and clamping as well as vacuum chucking on the lathe. He sells everything you might need at extremely good prices, including an excellent vacuum chuck gasket material.

    You may want to check this one out just ran across this while looking for tools https://www.harrisonspecialties.com/...s-accessories/

  9. I use the Oneway Rotary Adapter on my Jet 1642 (currently sells for about $85). I don't know if it can be used on the 1442. Removing the hand wheel and placing the rotary adapter takes me less than a minute (two set screws) so it's not an issue for me.

    After pondering all of this and watching a few videos, I made myself a very nice chuck that doesn't require an adaptor using a threaded lamp tube and ball bearing. Works very nicely!

    Thanks, all.
