Hello all,
I'm not sure if this is the correct place for this post but as it relates to a euro mill it seemed to be appropriate.
I have an early Thiel Duplex 158 which I believe dates to the mid to late 1950's. Unlike the later 158's which have an MT5 spindle my early model has the same apparently unique spindle as the 58 which is more like a lathe collet spindle.
The collets have the same dimensions as a DIN 6341 Typ 386E (Weiler I think) but with a 31mm dia and an 18TPI buttress thread which is an unusual combination of metric and imperial standards (see photo below).

The machine came with a selection of horizontal, stub and shell mill arbours and a near complete set of imperial collets from 1/8" to 1" but unfortunately the 1/2" was missing. I have seen tooling for these machines come up on German eBay only half a dozen times in the five years I've been looking and the sellers often will not ship outside Germany or Europe. I have been lucky enough to get a set of metric collets, drill chuck arbour and MT2 & 3 adaptors from eBay but a 1/2" collet still avoids me.
I thought it might be worth putting a post up here in the hope that perhaps someone out there might know of somewhere or someone who might be able to help me find this elusive 1/2" collet.
Cheers,
Greg.
