As has been previously mentioned on this and other forums the Jet Mini Lathe has always had a tailstock creeping problem which sometimes requires relocking the tailstock from time to time.
Keith Outten has designed a square washer/block to replace the round one under the tailstock. He sent me one a couple of weeks ago. I only got around to installing it yesterday and all I can say is "Wow". It makes a huge difference in the stability of the tailstock. Thanks Keith ! ! !
I am sure Keith would be willing to make some more of these to sell if you are interested.
