    The spindle bearings do not HAVE to be precision class. It depends on what you want to do with the lathe. I had to replace the taper roller bearings in my old Sheldon 10" and I talked with one of...

    A nice feature of the South Bend hobby is that it's your lathe and you can run it the way you want. Rolling smoke if that's what you like or nice and easy if that's what you prefer.

    I think you'll find that those small South Bend lathes, particularly the 9" Workshop, were designed for use with relatively small drive motors because they were intended for modest workloads and...

    1/4 HP is absolutely adequate for running a 9" South Bend. My 1936 Workshop 9 ran with a 1/4 HP motor for the 50 years it lived at my dad's house. After I inherited the lathe I changed it over to...

    Wow! Nice looking job. You painted yours. Mine is still in the black oxide left over from Oxy/Acetylene welding the parts together. The finish sort of goes with what's left of the original finish...

    I have 3-jaw chucks in both configurations. There are plus and negative aspects for either configuration. With the 2-piece jaw, you don't have to worry about taking jaws out, keeping track of them,...

    Anybody with a lathe can make his/her own threading dial body. It's handy if you have a welder and milling machine but you can do it without a great deal of effort using just the lathe and 4-jaw...

    Or, take a piece of 600 grit paper and wrap it around a known good #2 shank. Don't let the paper edges overlap but leave a small gap between the edges. Gently use the shank and the paper to buff...

    We need to know a little something about the motor that's powering the lathe. Since it looks like a home rather than an industrial setting I'm assuming that you do not have 3 phase power. The...

    That's a sad, sad lathe. There is a small, and I mean small, chance that there could be a functioning machine hiding under all that rust but I'd bet against it. As mentioned, the lack of the change...

    Rummaging around on the "Lathes.co.uk" website archives, I find mention of early Sheldon's running spindles directly in the headstock casting but using bronze shims under the bearing caps. I didn't...

    I'd suggest maybe the bearing caps are not shimmed correctly and that adding a couple "thou" to the shim packs might make it so that the cap bolts can be tightened.

    My theory is that the Heavy 10 reversing tumbler is noisy because the two gears run pretty fast in comparison to, say, the 9 and 10 models. Look at the diameter of the gear on the spindle and then...

    I agree there's little reason to purchase a 145T motor for that lathe which is going to be quite expensive. A 3/4 - 1 HP 56 frame motor would be more than adequate for the job. The mount holes for...

    There is no "1451" NEMA frame size motor. It's most likely a "145T" which is a fairly common item in the 1 - 5 HP range. You can find them on eBay or at some of the surplus outlets such as Surplus...

    If the motor runs with the belts off, even though it gets hot, there is probably not a problem with the starting switch. If the start switch does not work, the start winding will not be powered and...

    I could be wrong (lot of that going around at my house lately) but I do not believe that to be an original South Bend color from the 1930's. Regardless, still looks to be a very nice lathe.

    Side oilers do NOT necessarily indicate bronze bearings. My 10L has segmented iron bearings along with side oilers. Bronze bearings appeared sometime in the 1940's.
