Re: Metric South Bend 10K

Seen from the top, the acme screw engages with the bull gear at a slight angle. I adjust the angle in order to eliminate the gear backlash. System works very well for me. It is not as rigid as a real ldividing head but, it does the job. It turns easier in the clockwise direction.
if I was using it more often I would change the clamping setup on the front of the headstock instead of the bed.
 
IT Takes about 5 min to set it up.

Guy,

5tpi Acme to approximate the 16DP bull gear?  I like the indexing set up and was wondering how well that works for you.  Your results look great.  I'm just curious about the worm engagement in the straight tooth bull gear.

Thanks,
George H. Meinschein, P.E.

IN my case a dial on the xslide works perfectly.  I have both imperial and metric micrometers.
The metric dial enables me to go straight from the mike to the lathe without going through a calculator, and brings me to 0.01 mm of the target value. The real important is the last quarter of a turn on the dial. Measuring dial would be an option if I was doing it on an occasional basis
i already have a dial with 254 grads on the lathe, 1.75� dia but I am upgrading to 2� dia after I realized how convenient it is to read . I rebuilt the xfeed screw on a 9A for a friend with large dials and he wanted 2� dials.

Howdy,
 
I can understand boredom but making an annoying metric dial to put on an inch lead screw?
Such things exist on some lathes and are useless.  No machinist is going to read past 254 nor 317+!
A digital read-out is the answer if volume justifies the expense.
Otherwise, any accurate work involves a travel indicator; hence, investing in both an inch and a metric indicator is the way to go.
 
Best of luck,
 
 
OK

Re: Twin gear box

bill Tabor
 

Yes the lead screw stops turning with the split nut in open position. I have notice with a flash light if I put the second tumbler in any screw pitch thread and leave the first tumbler or the speed a-g tumbler out all 3 of my drive gears turn. When as I put the first lever into e or f speeds only the first 2 main drive gears turn the 3 stops as I dis engage first lever all 3 drive gears turn, Now when I say 3  drive gears the gears are pined in pairs so you have 3 pairs on the tree shaft and 3 on the drive shaft.
Only the first pair are keyed the other pairs free wheel. According to SB manual f and g drive gears are pined as a pair been thinking of pinning them to d and f gears though the manual don't show doing this. Sorry for not getting back to group but had a death in the family.

IN my case a dial on the xslide works perfectly.  I have both imperial and metric micrometers.
The metric dial enables me to go straight from the mike to the lathe without going through a calculator, and brings me to 0.01 mm of the target value. The real important is the last quarter of a turn on the dial. Measuring dial would be an option if I was doing it on an occasional basis
i already have a dial with 254 grads on the lathe, 1.75� dia but I am upgrading to 2� dia after I realized how convenient it is to read . I rebuilt the xfeed screw on a 9A for a friend with large dials and he wanted 2� dials.
I have the luxury of having 2 almost identical SB.  Since I am doing metric work quite often, I have one that is geared permanently with a transposing gear. The metric dial makes me save time
I saw metric dials on Busy Bee lathes and stamped my first dial in hundred of mm, based on what they had on their machines. The original SB dial is stamped in mm.  My next dial will be stamped in mm if I can find a dot punch 
Scribing  the dial is done on the lathe with a headstock dividing attachment that uses the bull gear  to index.  a worm meshes with the bull gear and a dividing plate is fitted at the end. Covid19 sut down is perfect timing for this type of work. On this lathe I might re machine the saddle in order to fit Turcite on the sliding surfaces.

Howdy,
 
I can understand boredom but making an annoying metric dial to put on an inch lead screw?
Such things exist on some lathes and are useless.  No machinist is going to read past 254 nor 317+!
A digital read-out is the answer if volume justifies the expense.
Otherwise, any accurate work involves a travel indicator; hence, investing in both an inch and a metric indicator is the way to go.
 
Best of luck,
 
 
OK

The dial on the left is a 10K(1.750� diameter).
On the right is a 10L (2.250 diameter)
BTW: they are both for sale

A picture worth a thousand words

for 254 divisions I use a 127 hole plate with 38 spaces.

Takes about one hour to scribe a dial if you use basic line length

Re: Metric South Bend 10K

eddie.draper@btinternet.com
 

Our 18" (36" America) Broadbent lathe at the railway is Imperial.  On the cross and compound slides there are imperial dials fixed to the screw, and concentric, geared to them are metric dials.  Haven't had one in bits yet, so no idea what goes on inside.  Can't recall ever having referred to them, though.  I keep a cheap solar powered calculator with large buttons & display to hand in the workshop, as we have both metric and imperial machine tools.  You just need to remember the magic number, 25.4.  Most of our measuring kit is still Imperial.

But I agree, a DTI on a mag base is fine for occasional use.

Howdy,

I can understand boredom but making an annoying metric dial to put on an inch lead screw?
Such things exist on some lathes and are useless.  No machinist is going to read past 254 nor 317+!
A digital read-out is the answer if volume justifies the expense.
Otherwise, any accurate work involves a travel indicator; hence, investing in both an inch and a metric indicator is the way to go.

Best of luck,


OK

The dial on the left is a 10K(1.750” diameter).
On the right is a 10L (2.250 diameter)
BTW: they are both for sale

THanks for the picture
I am about to scribe a 254 graduation dial for my 10k. I am not replacing the standard feed screw. 
since I am not changing the feed screw . the dial on the picture with 250 grad will not work on my lathe, but guides me on how to make proper markings
Manufacturing dials is easy if you have proper tools but not cost efficient

Re: Cross slide and compound backlash

glenn brooks
 

A good indicator of wear for cross or compound screw and nut is inconsistent DOC and finish when making final cuts. Slight concentric circles in the finish cut means the thread angles on your screw are worn, causing the tool post to ride up and down on the threads as it passes along the work. Same with holding a consistent DOC. A worn screw means sometimes never being able to achieve the same rate of removal.

my SB Fourteen had these same issues. Sometimes DOC varied up to .010” with the same amount dialed in. I had a shop make up a new screw and nut and now it’s rock solid.

BTW, both parts wear against each other. If the nut is worn, you can count on the screw to be worn also. If you are tearing everything down for a rebuild, why not renew the clearly suspect parts and make it new again?

Re: Cross slide and compound backlash

Loosen up the gibs on compound and cross slide slightly and set up mag base and dial indicator on front or rear face of slides. Push and pull on slides, read wear on dial indicator at various positions on the screws. New nuts should improve the backlash. The nuts are bronze and meant to take the brunt of the wear rather than the screw.

Matt, crossfeed nuts are on e-bay for the going price. i would start there and with the nut you can see if in fact the crossfeed screw is worn, or if budget permits buy one of the complete assy.

I have the one screw out and can wiggle ithe nut 15 or 20 thou on the screw up and down and lengthwise. The screw looks to be in good shape on the entire length. So do I just need new nuts to get rid of the backlash?

Re: cam tailstock lock modifications for SB13

For what is worth, on my SB 9A I am using an offset box wrench with the opposing end cut off and contoured. Exposed end is coated with PlastiDip. Works better than the original since the shank is narrower and allows for few more degrees of rotation. Old wrench which was (is) aluminum and all stretched out and kept falling off the nut and kept banging to the stops too soon.
