I guess I better stop shifting under power :)

+1 on the gear repair, easy fix and nothing to lose.

If you want to make one, all you really need is a rotab or even a spin index, a form tool can easily be made from HSS, and a divider from CGTK - Divider Wheel Generator

Mark,

I think turning the radius into the base will make that joint quite strong.
The finger bolt arrangement squeezes the Al, so that should be no prob.

I would say, "Make it" with an eye to costs, so if others want one,
you know what to charge. 
The CI ones on eBay cost an eye and a foot.

One other option is to use a steel round for the ring but THAT BE A LOT OF BORING to get a 4 1/2 “ hole in it.
    That is my idea anyway. Just wondered how harebrained it sounded. As soon as my hold down clamps get here that Burke has a lot of work to do.

Mark,

 
I think you could even bore it out to 1/2~3/4” wall thickness and still be stout enuff
over 2” length.
 
The stress will be along the length of the fingers,
so reinforce the threads in the Al with steel nuts on both sides of the ring.
 
The other stress point will be the point of attachment to the bed.
Try to make it a wide and long as possible to distribute the bending torque.

option 4:
repair this hear.
Looks like two separated broken teeth.
Dremel the base flat. Drill for 1/8” steel rod or tap for 1/8” steel bolts.
Insert steel, grind file to shape.
If you want fancy, epoxy over the steel to shape the tooth profile.

I have done it both ways and it works.

A 2" long tube of 6" OD with a wall thickness of 1 1/2" made of aluminum can take anything your 9" can throw at it.

I have a 3/4 hp variable speed DC motor for sale or trade if anyone is interested.  ($75.00 + shipping)
 
Bought it used in 2007 for my Atlas lathe, and shortly thereafter bought a South Bend 10L, so I never used it.

Measure the gear you have, and apply the following formula:

(number of teeth + 2) / OD = Diametral Pitch. The Pressure Angle will be 14.5

[Attachment(s) from james.rice@... [SOUTHBENDLATHE] included below]

Does anyone know what pitch diameter and pressure angle are the gears in a South Bend 9 QCGB? I recently purchased a 9A that is almost perfect except it apparently was shifted under power.  It was a lathe from a trade school.  The gear I'm needing is one of the pinned together cluster gears part # PT626NK1 which**- is pinned together as assembly AS622NK1.  This is the second gear cluster from the end of the shaft on the left hand side of the gearbox.  The smaller gear is in good shape but SBL never sold the larger gear as a separate part as far as I've been able to determine. I made a phone call to Grizzly/SBL parts in Springfield but was told at his time the gear cluster is NLA and if it should become available, the cost would be upward of $350.00.


At this point I can:


1. Buy a gearbox on eBay and either pull the gear I need for installation into my gear box or just mount the purchased gearbox on the lathe.  Cost would run from $150 to $300 depending upon the end price of an available gearbox but I would have a number of spare parts for future use.


2. Keep looking for a gear from some one who might have it in stock or left over in a damaged gearbox.  Cost unknown.


3. Make a gear.  I realize that isn't as easy as it looks but I believe I could do it.  I own a Clausing 8540 h. mill.
