Buncha' American South Bend Heavy 10'ss on eBay

[JerrySharrett]

Several Heavy 10's on eBay right now. Good prices but, some with fresh paint jobs..Look repaints over more closely.

Some have leaver type collet closers..these may have been production shop machines...usually OK but the spindle bushings may have excessive wear...most times an easy fix though.

I haven't found a source of new old stock spindles and bushings. I also have not heard of anyone making new bushings and resurfacing old spindles.
That being said... how would worn out spindle bushings be an easy fix?

Looks like the majority of what I've seen on eBay lately in the way of Southbend Heavy 10's are located in Rhode Island or Massachusetts. Might not be too bad a trip for East coast shooters, but a long ways from the middle of the country.

Some bushing type lathes that were used in mass production will have very worn bushing/shaft fits. Most of these can be identified if they have lever type collet closers. And some of these can be brought into reasonable working fit by removing all the shims. Even helped with one where we put shim stock on the outside of the bushing halves. If the shaft is scored probably a tougher fix.

Used to be a guy who had a used parts place in New Jersey under one of the bridges (Tapanze, GW, ?). Bob White may know where he is.

I cannot understand why someone with a CNC shop hasn't made new replacement bushings. I was looking at a spindle thinking about taking it to a crankshaft shop to have the journals welded and ground back into spec but when I couldn't find any new bushings I gave up the idea. (Still not sure if it ever was a good idea.)

Spray coating not welding would be the best way to build up the spindke journals. Better yet, since you are making new bushings, turn the shaft journals to clean up (cylindrically grinding would be best) and make the new bushings to fit those diameters.

But keep looking, there should be SB 10's being parted out if you cant fix your problem by shimming the bushing OD's.

BTW, how much "play" does your spindle have?

Mine look like brand new, I have right at .001 play measured by the method described in the rebuild manual that sells on eBay. I have some parts laying around and I've thought about another Southbend so the thought of having brand new bushings or sleeve bearings has been on my mind some.

My old South Bend 10 L

Was made in 1943. It doesn't have enough wear on the spindle or bearings to worry about, doing the work I am capable of, being a human and all so why worry about it? It would take running one of those old machines without oil for guite awhile to damage them much, from my experience. Not likely to happen from what I have seen. I can see and have recently experienced a gear box being worn out but not likely a spindle and bearings. Bought a gear box for it's shift handle and, not only is the handle worn out but so are all the gears, UNBELIEVEABLE! I was a bit too eager in my purchase. My old gear box is tight as tight can be, oh well, Nursing Home Money.

Should be easy enough to get a spindle ground and many of the 10Ls have lamanated shims on the bearing caps. Plain bearings are easily to scrape in as well; that's the proper way to fit them.
