    Hardinge makes a very nice quick change tool post for their manual lathes. The L20 2-wheel knurling tools for it are the cut type. I find them tricky to adjust.

    If the pitch is 8 TPI and the OD is a little more than 1.5, I would consider taking the spindle out and getting it machined to a true 1.5 inch x 8 TPI, perhaps using a new chuck, adapter plate or...

    A split point drill was mentioned, but I will add that that type drill is excellent for drilling into a round rod. The parabolic flute feature is fine, but not necessary for starting and continuing...

    Stiffness. The numbers I have been carrying around in my head for decades are Steel-30, cast iron-25 and aluminum-10. Higher is stiffer. These are the easy to remember, non-technical numbers that...

    Gray and grey are sort of like color and colour, but the distinction is actually more complex. Both spellings were used in England for many years, but the current usage is that Americans favor gray...

    Any yardstick will have marks at 1/8 inch intervals, perfectly adequate for determining if the thread is 8 TPI.

    I wondered if the OP has a tiny spindle with M7 x 1.5 threads.

    Mill Ser. No. 47-16264 was built at the end of 1941, probably after Pearl Harbor. The 47 means the head is 7" swing and it takes 4C collets.

    In my last printed Hardinge catalog (1990), they showed the 2 MT and 3 MT SFJ live centers. No prices, of course, and they did not mention that they were imports.

    I found a used 2 MT version...

    The general rule for pronouncing names, given only the written form, is that you still need a vocal demonstration to hope to get it right. And you still may not get it.

    It is very unlikely that you can find a source of "sets" of only round dies without taps and handles, so look for individual sizes that you actually expect to use.
