I'm trying to find an adapter for my 8mm Pultra - these seem about as common as rocking horse droppings ! I saw this Boley 8mm adapter and wondered if it would fit A bit of research on WW collets (Robert Bastow) suggests it might be "I say this because it is known that the WW threads are originally an anglicized version of the original 8mm European sizes..of which there are MANY..most of which are interchangeable with WW collets, drawbars etc. It is also known that, in order to facilitate this interchangeability..drawbar threads are purposely cut to maximum sizes Thus, if you have a drawbar tapped to the above spec..either .275-40 tpi H2 or the equivalent metric size 6mm x .625mm you can use WW or 8mm collets in it from all the following manufacturers..my sizes are taken from "the Model Engineers Handbook" by ..Tubal Cain..the other guy..the REAL ONE as someone said!! 8mm collets from Adams, Boley, Boley-Leinen, Coronet, Derbyshire, Pultra and WW are all threaded 0.268-40 and will all be a fairly sloppy fit in your drawtube." Has anyone real experience with this ? to establish if this does work ?
