Hello again,

I have a 60 year old Herbert preoptive Lathe. It is quite huge and I
have a chuck with a very bad case of worn out scroll. *My question is:
is it possible to replace the scroll and the jaw carriers, or what
ever they are called. or would it be easier to get a whole chuck, -
there is no runout on the body of the chuck? *I get runout that varies
over about 20 thou, depending on which bit of the scroll is in use.
What about the chances of finding a 4 jaw that would fit on the 3 stud
fixing. *Does anyone have anything that is better than what I have
that is no longer in use? *Anything considered. *I am near Norwich.

3 stud lathe chuck? Give me the diameter and the pin sizes and Ill see
what I have.

My Clausing 1500 is a 3 pin removable chuck and I have extra stuff

Hi Gunner,

thanks for the reply. I have posted a few photos of the Herbert Chuck
on my website.
http://www.maribelecosystems.com/OldEngines.html There is a calliper
shown which I used to measure the diameter of the flange onto which
the chuck mounts.
I hope you do have something.

Thanks and regards George.
