>Has anyone used this product from Packard? Mikeincapemay sent me the link ....my tpi is 1/14 x 8 and so I can get a wine bottle stopper chuck for a reasonable price. Given that I would only be turning stoppers, what are your thoughts on using this in teh head stock and then getting the $10 bottle stopper thingy?
The Packard tailstock adaptor is made of soft aluminum. There is almost certinaly a little runout.
The bottle stoper chuck is little more than a screw chuck with a 3/8" bolt for the screw. You could mount such threaded stock in a jacobs chuck or in pin jaws of a scroll chuck to get the same sort of bottle stoper holding.
>I use the 1 -1/4 x 8 one regularly for centering segments. It is not meant to be used under power so certainly shouldn't be used for adapting a chuck.
