MicroMark 7x14
I also was thinking of getting one of these machines. I am currently trying to figure out if I want one of the 9x20 lathes or 7xX. Wonder if anyone in this group has purchased one yet. I would love

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

Collets
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 a good discussion of the advantages of the 6-K collet over the

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
I'm working from the pdf files of articles written by Exactus: http://groups.yahoo.com/group/mlathemods/files/LatheColletChucks/ As you suggested, he has you make the collets in pairs and gives the

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 of info one would pick up as an apprentice in a machine shop, I guess. I'm looking around for a new steel collet for use as my

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

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
