Thanks Ken and now Daniel. I did go to Lee Valley last week and they don't carry such a thing like these. I have put a piece of 1/2 stock in my collet chuck and treaded it to 3/8 but there is too much runout unless it is treaded on a metal lathe. I did't used to be that fussy till I joined this group, then looking at different articals and video's made me this way. Thanks to all at IAP that makes you a better turner.
Lin.
