    Page 101 says 127 / 90 compound for the ten inch

    http://vintagemachinery.org/pubs/2102/6810.pdf

    This is circa 1946. There are of course older Regals

    Here is the entire LeBlond list at VM - the two sections of Running a Regal (from about 1946) can be easily found

    R. K. LeBlond Machine Tool Co. - Publication Reprints | VintageMachinery.org

    In that list is the older (guessed at 1934) Regal catalog - which at least tells you that the lead screw on the 10" is 8 TPI

    Give us a description of the tooth counts and layout of the original end gearing, and a list of the pitches the gearbox cuts from the factory. With that, we can calculate alternative ways to get metric pitches.

    A 127 / 90 will be a 127T gear fastened to a 90T gear and working together as one

    Looks like the English language has gone full circle from birth to an agonizing death in its homeland.

    We can probably make 100/127 work just as well as 90/127, so don't buy anything else until you tell us what the old end gearing and gearbox options are

    I can't resist throwing this comment into the mix, given tdmidget's comment:

    The OP's English & spelling are on point, but his sentence structure and the compound gear train on his LeBlond lathe are one and the same. He expresses himself well, but the writing of his posts are the mothers of all run-on sentences. Call it "running the King's English through a set of compound gears".

    Years ago, I was gently taken to task on this 'board for not setting my thoughts apart using paragraphs. One poster (Jim Rozen, possibly), defended me, saying I was writing using "stream of consciousness". Now we have another person posting who is using "compound gearing" to structure his writings.

    The main thing is we understand what the OP is asking about, he is articulate, and he is respectful. Though never a smoker, I am old enough to remember a cigarette commercial (Winston cigarettes, I think): "What do you want ? Good grammar or good taste ?" We want people interested in old machine tools, and we want people who own/work on/restore and appreciate old machine tools and machine work. The OP is all of that. Forgive him his grammar, even if he is in the birthplace of the English language.
