I own a newer Sherline lathe and purchased a Sherline Collet set with sizes from 1/16”-5/16” which includes the draw bar and WW collet adapter to use with it. At my Club’s Mart I recently purchase five additional collets that I thought would fit my Sherline lathe, they do not. The diameter of these collets is slightly too large to fit into the adapter that came with the Sherline set. I measured the Sherline Collets at 7.95mm and the other’s at 8.03mm. Because of this small difference these collets will not completely enter the adapter and therefore cannot be screwed into the drawbar (second photo). If I try to install the collets without the adapter they are too long (last photo). Does anyone have a suggestion on what I can do to make these collets work in my Sherline lathe? I have included several pictures that I hope will help explain my situation. Thanks for the help.
