Greetings,

I am looking for a cross slide handle for a SB9" lathe, or something very similar that would fit and work.  Lathe is a 1923 era SB9 with quick change gear box, with the single lever, dog clutch box.  I do not have reference material to look up a part number.

The lathe belongs to a friend, but I helped him buy it and I assisted on an earlier repair of the carriage feed gearing.  I just completed repairing the cross slide screw, which broke.  In the doing, I converted it to large dial (100 grad.) using a large dial assembly I had taking up space on my shelves from long ago when I had a SB9A in much need of repair.  I installed two sets of thrust bearings and a deep groove ball bearing.  No backlash in this assembly. The handle that has gone missing is shown.

So, my friend and I live 2000 miles apart.  He shipped his saddle and CS with all the parts to me, sans the CS nut.  I did the repairs and just shipped it all back to him, using his packing materials.  Priority Mail.  He received it today.  The box had come open during shipment and the handle is now missing.  He is going to try the compound handle to see if that is an interim fix.  Even so, that handle will have to be replaced.  

My guess is a handle from a different model of SB lathe, even larger or smaller, may work.  Through hole is 1/4" ID with a 1/8" keyway with a round key/pin.  I'll work out any key/pin issues.

Re: Magnetic Chuck Question

After watching a few of the You Tube videos, make sure you match mark things before you disassemble to save yourself some reassembly time.

Magnetic Chuck Question

wlw19958
 

Hi There,

I know this is a little off topic but I am looking for information
about disassembling a permanent magnet type chuck.  I have
read that removing the magnets will severely weaken them.  
So, if anyone has any information or experience they would
like to relay, please let me know.

Thanks in advance!

Playing around with metric conversion

carbure2003
 

A few weeks ago I made the decision to convert to metric my SB 9A.

As I do metric work on a regular basis, I kept the metric transposing gear on the machine. I also replaced the dial for a metric dial on the cross slide. It is a 254 graduation dial. Every graduation corresponds to 0.02 mm diameter. Dial was cut on my 10K. (attached photo)

It is not a big issue since I have a SB 10K sitting just besides.

Ten years ago I was offered a SB 10K metric that I declined at that time. Now I regret.

Next little project will be a rotary broach. It will require some metric threading as well as boring metric holes for bearings.

I just finished the rebuild of a SB 9A for a friend. Machine will probably leave my basement this week end.

I used a plater's wire wheel.  These are extremely fine wire
wheels (like about .003-.004" diameter wire) and produce a
very fine (soft) finish.  It also cleans out the valleys of any
crud.

This kind of wire wheel is so soft, you cannot hurt yourself
when your hand contacts the bristles (even if you leave your
hand in there a long time).

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!

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.

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!

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!

Hi There,

Thanks for the compliments!  I use a scissors type knurling tool.

How I wish I could do knurls that nice.

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!
