Hi
How's the fit and finish on that machine? I was thinking of getting
one.
Thanks, Frederick C. Wilt

Re: Spindle Runout on 7x14
The actual reference surfaces are the face of the spindle and the
outer dia. of the spindle nose; the outer dia. of the spindle is not
a reference. IIRC, the mini-lathe.com and/or

Page 50 of the HSM for Sep/Oct 2002 has an article on making
3-C and 6-K collets with dimensiond drawings and good details. There is

Hello All
I am looking for the parts to put a collet system on my mini lathe
also. Now one might ask what size collets other than 3c can I use,
well here is a site where maybe some of those

Re: 3C Collet Chuck, etc
Thanks for the information. Somewhere I have seen a dimensioned drawing
of a 3-C collet; if I find it I will get it to you. I suspect that you
are "skating" the tool tip on the chrome plate. You have

Re: 3C Collet Chuck, etc
Hi Bill,
The diameter of the shock absorber rod is 0.865 while the large end
OD of the collets is 0.830 so I can't be too sloppy when centering;
the body OD is 0.650. This shock was bigger than

Re: 3C Collet Chuck, etc
I am surprised that the strut rod steel is hard to turn as it comes from
the strut! In my experience once you get under the chrome plate it is
very nice turning. Except of course where it has been

Re: 3C Collet Chuck, etc
A lot of helpful hints in your post, Roy, thanks. This is the type

Re: 3C Collet Chuck, etc
My choice for a "standard" collet would be a pristine steel one,
from one of the suppliers who states accuracy. I'd use it to hold an
accurately ground test rod - dowel pins are good. I've had

Re: 3C Collet Chuck, etc
The collet is a new SB, sk-polishing offers these frequently on eBay
and I took advantage when one didn't seem to draw many bids. I have
accepted it as a standard in testing my collet chuck, at

3C Collet Chuck, etc
I measured my 5-C spring collets and found less than .001" taper from
the threads to the closing cone!

Re: 3C Collet Chuck, etc
I wonder if the brass collet is part of the problem. Coming from
e-bay, there's no telling what sort of abuse it may have suffered.
Steel collets are "spring hard" to avoid distortion during

Re: 3C Collet Chuck, etc
Based on building a 5-C adaptor I believe that the bore should be
straight to align the collet body coaxially with the lathe axis.
