South bend 9a feed change lever
The 9c is the only version that doesn’t have powered cross feed. Sometimes when it sticks try turning your cross feed dial handle while your trying to engage it. Otherwise you may need to oil it up.- mcruff

Bench recommendations for a 9A?
My 3' South Bend 9" Model B converted to A. I converted mine to Serpentine back in 2003 or 2004, a 1 piece serpentine belt is in no way comparable to a a flat leather belt. They are smoother, use no belt dressing and will allow nearly twice the depth of cut due to no slippage and have no...- mcruff

Lubrication 101
For the spindle Mobil Velocite no 10, the backgear gets Super Lube synthetic grease. #2 way oil for the bed and a modern machine oil equivalent for the B oil, somewhere there is a saebolt oil viscosity chart that converts to ISO that lets you cross reference these oils to modern equivalents. It...- mcruff

Gold plated (?) 9A for sale in Utah
That’s a war production machine, the ways were never frosted. They are scraped flat and that is all. There will be other characteristics that are similar. They are not fit and finished to the degree of the ones after the war. If you pull the head off you will find the scraping is a match to the...- mcruff

9" Model B--motor needed
If you really want to use these 9” lathes, go get a modern 1/2hp 1725rpm motor and while your putting it on swap to a serpentine belt drive. If your machine is a horizontal drive do yourself a favor and remove the spindle to put the belt on, do not cut and splice it unless it is an underdrive...- mcruff

Old lathe found in shop
This is the real story here, war production machines were scraped finish but the beds did not have the cosmetic frosting that civilian era lathes had. The machines were finished just not to the normal cosmetic standards before the war. You could not buy most machines during the war unless you...- mcruff

9" Model B--motor needed
Definitely don't go below 1/2hp 1725rpm motor, I run that on mine with a serpentine belt and I can take a nice healthy cut. Pitch the leather belt, get a 1" wide serpentine auto belt, knock the spindle out and replace the belt. If you leave the belt intact and don't try to splice it with glue or...- mcruff

1940 9A Missing Plates
Mine is a 1942 war production lathe, mine has the lube chart and the gear change plate on the gear cover and a war production board tag on the bed about 4” from the right end in the side of the bed. My lathe has no frosting on the ways and was scraped roughly compared to ones before or after the...- mcruff

Thread dial replacement
On page 22 of the what have you made for your South Bend lathe is a picture of the thread dial I designed and printed. It is printed in PETG which is pretty tuff material. The rest of the thread dial parts are made of mild steel of which I made. I printed the part and left about .010” in the 2...- mcruff
