Sorry, I meant to add this to the previous post
I think this is the chuck...
https://www.recordpower.co.uk/product/12-drill-chuck--1-morse-taperbut I can't remember where I got it from...It certainly looks quite old.
Maybe I should explain that I've been away from lathe work for fifteen years
or so. I was quite a beginner then, but change of job forced me to
give it up until recently. So, I'm kind of starting again, trying to forget
old bad habits, I've become interested in penmaking but now starting
to get back to small bowls, vases thingies etc. I'm guessing
that I got this chuck from ebay or something similar in my previous
time.
It does'nt owe me anything, but, would be nice to get it going again
just out of sentimentality (if not, to save money !!)
Best wishes - Jim
