nice work.

Hi There,

There hasn't been much posted for awhile so I thought
I would show what I've been doing. 

Over the weekend, I made the depth screw for my threading attachment.




When I got it, the screw was too big in diameter.  After a little research, I discovered
that the threading stop for the 9 inch and 10K.  I had an NOS one I bought back in the
1980's.



(you can see the "too big" screw at the top of the picture).
I measured the 9 inch/10K screw and made a copy.  I made
a few cosmetic changes to the head to make it look more like
the style of the bigger one.



One of the changes was to use a 45° diamond knurls instead of the 30° ones.
(They are a little more South Bend-like). 

The other thing I did was to make a replacement oil tube for the one that was
broken off in the reversing gear tumbler.  I measured the one in the reversing
tumbler I borrowed from another lathe and bought some heavy walled (.065")
260 brass tubing.  I already had a 5/16 x 32 tpi die. to thread it.  I drilled the
other end out to 1/4" so I could drive a Gits oiler into it. 






I also repaired the broken gear bearing journal.  I took some pics with my cell phone
but they didn't come out good but I do have one of the completed journal assembly.



Originally, the threaded end had broken off so I cut the nub off just at the undercut
behind the threads, drilled and tapped it, threaded in a new section (using 1144
steel).  Then I drilled and cross-pinned the insert so it won't come out.



(If you look careful, you can make out the outline of the pin). 

Now I have the original reversing tumbler assembly back in my lathe (and it runs
quieter than the other one)!

So, my lathe may not be the "prettiest" lathe, but it pleases me.  Thanks for letting
me share my small activities.

Good Luck!

Hi There,

Thanks for the compliments!  I use a scissors type knurling tool. 
The "secret" is to use plenty of oil.  I mean, Plenty!  I Have a pistol
type pump oil gun and I am squirting oil over the knurling wheels
all the time I'm knurling to flush away the chips that come off.  I also
reverse the spindle rotation now and then too.

The latest task was to make a copy of the knurled thumb screws for
a steady rest.



The lower one is the original and the upper one is my copy.  Mine was
made from 1144 Stressproof steel.  I started with 1/2" rod and the finished
product comes out .497" in diameter.  The original is slightly larger (measures
.520").  The pitch and angle of the knurls look right (mine being new, has 
sharper diamonds).

Good Luck!

How I wish I could do knurls that nice.

John,

I haven't knurled anything for years and haven't thought that much about the topic for about the same time.  The recent conversations triggered me to do a little online research into knurling techniques and I found the attached.  The pitch diameter & depth of knurl info might help you in getting to a finished product with a really nice appearance.

Thanks,

I've always thought the diamond pattern was totally hip and very professional looking. Not to mention that it provides a better grip with my beat up hands and fingers these days as I'm getting older.  Good PDF George!
