You might also say where you are located. There might be some soul on RCM that is close enough to you that they could help. Another option is to make one. If I recall correctly you could either hog one out of a piece of plate or make a weldment.

$295 - yikes! Definitely need to consider repair. Welding, of course,
but brazing would likely be enough. Compared to $295 for a new one,
taking it to a professional would be cheap.

I don't remember if the quadrant on that lathe is zinc or cast iron.
If cast iron any competent welder can either TIG braze or braze using
a torch. The part is small enough that it would be easy to heat the
entire part hot enough so that the brazing operation wouldn't lead to
cracking. If the part is zinc there is available online a soldering
alloy that works very well on zinc alloys. Pure zinc can be soldered
with rod available from the hardware store. Done properly the soldered
repair will be just as strong as the original part. All you need
besides the rod is a propane torch.

If its cast iron..and it more than likely is...brazing is indeed how
it should be done.

That source of course..is an utter ripoff.

From the picture here
http://www.searspartsdirect.com/mode...7/0728000.html
it doesn't look too difficult to make a stronger one from steel plate.
The slots wouldn't have to be very precise, the arc could be oversize
and the long one could wobble; both could be chain-drilled and filed
wide enough to pass the bolt. The raised boss for shaft 26 could be a
pressed-in bushing, maybe tack welded at the edges, or just a washer
if handle #8 holds the quadrant securely enough. What looks like other
keyhole slots for gear studs in the interior could be left off until
needed.

If the straight slot comes out too wide to restrain the square on the
carriage bolt #7 a hex head could be undercut with a longer step.

Well I am in Delaware, so not very close. But if you do not come up with a reasonable repair, let me know. I am not too far from a foundry ( cat tail foundry ) and could get a replacement cast. I have not done this before so there would be a learning curve for me. And would not be too speedy. I think they only cast about once a month.

==========================

It would be easy to make a functional steel copy with a bandsaw to cut
the blank and a milling machine for the holes and slots. The copy
doesn't have to be a precise duplicate; the user manually adjusts gear
engagement on the quadrant by moving the studs, and the mesh to the
spindle gear by rotating and clamping the whole assembly.

Sorry I didn't follow this whole thread, but I guess you have the idea
that welding cast iron is problematic and you'll get a wide range of
opinions about how it should be done. Weldors who can do it *reliably*
are not that common, although people I've interviewed at Lincoln and
Miller tell me that a simple job like yours can be done by most people
using arc welding and nickel rods. Several other methods can work, but
they require more expertise.

I agree with Jim. It's a simple piece that you could make out of mild
steel. I'd have it roughed out by someone who's good with a plasma
cutter (most commercial weldors) and then I'd drill and grind the
slots. Space the drilled holes so you can go back and drill *between*
them, overlapping the holes on each side, and you'll get most of the
metal out of there before you grind and/or file. Filing to finish work
like that is easier than you might think.

The result would be stronger and much more dependable.

Not likely. The Craftsman (Sears Roebuck) lathes were made by
Atlas. (And Atlas joined with Causing, so look for parts under the
Clausing name.)

The Logan lathes were sold by another big store chain, whose
name I *should* remember, but can't at the moment -- likely until just
after I hit "send". :-)

And, of course, there were also the Craftsman "109" series
lathes, made by AA and a lot more fragile.

Enjoy,
