broken cross-slide screw

And with the pictures, some numbers:

Screw threads are 10 tpi
Screw OD to outside of acme thread- 0.435”
OD of unthreaded shaft at gear- 0.373"
OD of crossed gear- 0.691”
Length of.      “        - 0.457”
OAL of cross-slide screw to end of nut securing handle- 12-5/8”

As you can see from the pics, whoever said the screw shaft bushing threaded into the casting was right on the money.  (Allan?) Picture of the casting underside shows how close the end of the bushing sat to the end of the gear when assembled.  Tried supporting the gear and hammering the protruding pin to drive the screw out of the gear.  Succeeded only in hammering the pin deeper into the screw shaft, which appears to be bored out at that location.  Used a plastic-head mallet.  See no signs of the gear being pinned to the shaft there, but the shaft is hollow where it runs thru the gear.  You can see pretty easily where the shaft broke.

Thank you one and all for your help and suggestions.

That should read: OD of crossfeed gear.  NOT crossed gear.  Sorry!

Steve,
I might have missed it, but do you know what caused the fracture?

Ok, just to clarify, does the gear fit through the hole in the front of the saddle when the bushing is removed?

Yup-pers!  That’s why it was so helpful to learn how to get it out.  Allan, to me it looks like: press get on unthreaded end of cross-slide screw, insert sc rew assembly, slide bushing over screw shaft and screw bushing into place, attach handle, machine away!

You suggested the threaded bushing, did you not?  If so, thanks!!

Not a clue, George.  First I was doing some gentle facing off, and then I wasn’t(!)

Hey, Freehold!!  Like your famous neighbor, my lathe was “boring in the U.S.A.”  Hoping to find a replacement screw abroad, if not here.

Yup, a Freeholder that done pretty good for himself.  In your spare time, can you indicate those broken parts and see if there's any runout?  I'm curious to see if the screw was bent a long time ago and finally gave up the ghost after flexing a zillion times.

Thanks,
George H. Meinschein, P.E.

On the later lathes, these screws are all one piece- 7/16-10 acme thread, an integral gear, a straight section for the bushing and dial to ride on, and a small threaded section to hold the handle nut on.

Yours was clearly two piece, perhaps some sort of repair. If the screw and gear are in good shape, I think you could make a new handle end, and silver solder over that stub you have protruding from the gear.

May be worth having a new cross slide screw (and nut) made up.  Even if you repair the existing one, you can’t do anything about existing wear on the threads.  I have had two machines that went from producing random, unacceptable finish cuts to near new machine finish cuts buy replacing the cross slide screw - AND nut.  

If this is a direction you wish to go,  my go to guy for making new acme thread assemblies is:

Bryan Miller.  
 

Also, Latheman Ted   is an excellent resource for finding NOS South Bend parts.

I would do that, George, but indicating on a piece of drill rod suggests my chuck runs out 3-5 thou’ all by itself, so I’m not sure how we’d separate the wheat from the chaff on that screw.  I can try that when I get a chance.
Wouldn’t have thought a screw in that position would be subject to much flex, but what I know about machine tools could fit in your eye without much discomfort.  It’s be interesting to know, though, you’re right.

Allan, that is EXACTLY what first came to mind when I saw the shaft section protruding from the handle was hollow, and I didn’t even know I already had a stub in place, since it was entirely inside the bushing.  I was thinking of welding.  My main hangup was not knowing how to extricate the screw assembly, but you fixed that.

My feeling is that if one of those Mod. 9A one-piece assemblies on eBay would fit, I would do that in a heartbeat.  I know that steel is tough stuff, but when it’s 95 years old, I think I have to cut it some slack and maybe look for an answer with a greater life expectancy.  Oh, well.  The search goes on!

Thanks, again for all your help.  Much appreciated.

Steve,
Yep, no flex expected.  Maybe the lathe got dropped on that handle at some point in the past 90 or so years and that's what set the stage for where you're at today. How about laying the threaded portion of the screw in one of the saddle's V-ways, give it a spin, and see if anything wonky shows up?  Of course none of this will help get you up and running, but maybe it'll give a clue as to what happened. 

Thanks,

Hey, Freehold!!  Like your famous neighbor, my lathe was “boring in the U.S.A.”  Hoping to find a replacement screw abroad, if not here.

Steve,
I might have missed it, but do you know what caused the fracture?

And with the pictures, some numbers:

Length of.      “        - 0.457”
OAL of cross-slide screw to end of nut securing handle- 12-5/8”

As you can see from the pics, whoever said the screw shaft bushing threaded into the casting was right on the money.  (Allan?) Picture of the casting underside shows how close the end of the bushing sat to the end of the gear when assembled.  Tried supporting the gear and hammering the protruding pin to drive the screw out of the gear.  Succeeded only in hammering the pin deeper into the screw shaft, which appears to be bored out at that location.  Used a plastic-head mallet.  See no signs of the gear being pinned to the shaft there, but the shaft is hollow where it runs thru the gear.  You can see pretty easily where the shaft broke.

Thank you one and all for your help and suggestions.

Steve,
Yep, no flex expected.  Maybe the lathe got dropped on that handle at some point in the past 90 or so years and that's what set the stage for where you're at today. How about laying the threaded portion of the screw in one of the saddle's V-ways, give it a spin, and see if anything wonky shows up?  Of course none of this will help get you up and running, but maybe it'll give a clue as to what happened. 

Thanks,

I would do that, George, but indicating on a piece of drill rod suggests my chuck runs out 3-5 thou’ all by itself, so I’m not sure how we’d separate the wheat from the chaff on that screw.  I can try that when I get a chance.
Wouldn’t have thought a screw in that position would be subject to much flex, but what I know about machine tools could fit in your eye without much discomfort.  It’s be interesting to know, though, you’re right.

Yup, a Freeholder that done pretty good for himself.  In your spare time, can you indicate those broken parts and see if there's any runout?  I'm curious to see if the screw was bent a long time ago and finally gave up the ghost after flexing a zillion times.
