capstan socket : why so expensive ?
Happy New Year.
Can you please help me with some keywords for google / ebay searches.
AM looking for a MT3 socket inside a straight sleeve, without being inundated by MT3/MT2 conversion sleeves etc.
Google helped me to find "capstan socket" but they seem to be relatively expensive + killer postage given that very similar things like MT3/MT4 converters cost far less. Maybe its simply an economy of scale with far more demand for the cheaper items.

Any other keywords that might find a straight shaft with an MT3 socket inside it please ?
Why ? Have realised that at times it might be convenient to be able to mount an MT3 ER32 collett chuck inside dividing jig on mill.
Found this thread re DIY MT3 sockets but it sounds like a lot of work to do it properly, and need to buy MT3 reamers.

Another option seems to be a MT2 taper to MT3 socket and cut the MT2 off the end of it. But the finish on the outside of the socket might be rubbish.

ER32 collets & tapers & straight
Thanks Gents,
I guess I was kind of blinkered by the fact that my current ER32 collett chuck came complete with MT3 taper and the mill and lathe are both MT3 tapers. Will ponder for a bit regarding straight shanks.
Quick aside - kind of related, but not really ....
I know some people mount their drill chucks on a straight shanks and then hold that straight shank in an ER collet, means less changing of the taper and drawbar.
And I know some people use drill bits in their ER colletts bypassing need for jacobs chuck.
Off to replace some rotten wood on the verandah and think a bit ..... thanks again.

Found some solid MT straight sockets
Am still interested in these sleeves for various reasons.
FYI : Best I could do is this one https://www.chronos.ltd.uk/acatalog/info%5fSOL11%2ehtml @ $14ish but then add postage UK to Aus and its a fortune.
Some also available at good prices in USA but again postage is an issue.
Anybody seen any available on ebay / alibaba / bang good ? I had a look but couldn't find any - kept getting swamped with the search engine giving me zillions of mt3/Mt2 conversion sockets.
