    It might not be a FULL MT#3 socket, but a standard MT#3 center will fit (perfectly) in a 9" spindle. It has a 0.602"/ft taper, same as a standard MT#3. Even the spindle opening of 0.938" (without...

    For turning between centers, the chuck isn't involved (other than for center drilling the stock). Looking at your available tooling, you already have everything you need for turning between centers....

    Pressing on the jaws is how Jacobs chucks are disassembled. I agree that a socket over the jaws and pushing down on the jaw holder would be a safer operation.

    That's not much in tooling.

    The live centers are probably pressed together, so they will have to be pressed apart. The drill chucks are the same way. Get the proper procedure online and use...

    That's not how it's supposed to work. Once engaged, the clutch is locked tight. If you want to prevent crashes, pay more attention to what you are doing - do NOT expect the clutch to do the...

    How often does it click? Is the click in phase with the spindle movement? +1 on checking your belts first for problems. It also could be a centrifugal switch that is sticking. Or a bearing.

    You have a 9A lathe, which generally should NOT require any shimming of the toolholder. Read Chapter IV of HTRAL on toolholders and the grinding of bits to get an idea of what you need to do to...

    The H10 spindle is a proprietary taper. It has the same taper as a MT#3, but has a larger diameter (1.628" at the large end). Your MT#5 backplate won't properly fit (if at all).

    You can't put a continuous belt on a H10. It has to be assembled in situ. It's better to use waxed paper or parchment paper to keep the glue off the jig. Make the jig out of wood, or aluminum so...

    Have you looked to see where the oil went? The oil cup emptying that fast indicates a problem. You most likely have the segmented cast iron bearings. These bearings have a wire clip that breaks...

    Probably the real original was made out of phenolic resin, that broke during its life. Some previous owner fashioned a replacement out of wood and gave it more life. If the contacts don't get hot,...

    Use Type C oil in the back gears too.

    Your mount looks fine. The handle only needs to "break over" when the belt is tight. As for leaning, as long as it doesn't bang into the rear of the...

    Having used Hardinge with the electric lead screw, I always wondered just what they were thinking. It was probably cheaper to electrify the lead screw instead of running it thru a gearbox.

    It is called "Independent Power Feed for 10" Lathes" by SB. Look in the 1967 catalog for info on them. Probably other catalogs, too.

    As for usefulness, I don't see why the geared power feeds...

    As for Q#2, stick with Type C oil for the cone lubs. The grease that is called for is no longer available and no modern equivalents exist.

    Whatever you do, DO NOT PUT GREASE in the cones.

    They are so hard to find because of the wide variety of sizes needed. I made my chip pan with some galvanized sheeting I got at Home Depot. A pair of sheet metal shears did the cutting (I believe...

    Get some thread and tie them down while you insert the spindle. Once it is in, cut the thread and pull the thread out.

    The "Type A" oil wicks very well. "Type C" oil works best using gravity to distribute the oil. The apron sump is a wicking system. Blindly follow the orders.
