oneway vacuum rotary adapter. This includes adapter for both powermatic 3420b and Jet 1640 lathes (I am not sure what other lathes these 2 adapters might fit). The one problem with the oneway system is that is very awkward to remove, which makes it very difficult to use a knockout bar to remove a Morse taper. My solution, which works GREAT and which I will include with the adapter, is a nut threaded onto the lathe with a large washer. You can back off anything in the Morse taper with a wrench easier than using a knockout bar.
new this is around $110 + of course the nut to back off morris taper items. I will sell for $65 and I will pay shipping to the continental US, or come pick it up in Madison and I will sell for $50.

Ronald, If I need to remove my hand wheel, I'll have to pass up your great deal as
I don't plan to leave it on my lathe as I periodically use my knockout bar.
 
You screw it on before you put on the Morse taper drive or whatever you are using. It does not get in the way and sits there (you cannot use this when using a chuck or anything that uses the threads, but you do not need to use it then). When you want to remove the taper, you just use a wrench and back off the nut which gently pushes out whatever is in the morris taper--easier and less trauma than a knockout bar

So the hole in washer allows the MT-2 shaft to bypass it and seat into headstock? Very cool, and simple fix. Thanks!!
