    Made with either 1 7/8 - 8 or 2 1/4-8 if it was the large bore version. no whitworth, no 55 degrees

    Assumes you do mean Heavy 10

    If you think it a 1 1/2-8 and johnoder says it a 1 7/8 or 2 1/4-8.. then you better had measure it with proper tools to be sure... that seems way apart..

    thanks Johnoder
    for the reply cannot get the chuck off at the moment (Seized)removed chuck from back plate and it only seems to be about 1.1/2"cant measure properly but the faceplate that came with it is 1.1/2" x 8 tpi but not sure its the right one the hole in the other end of the spindle is only 1" so I think its only a regular spindle not the larger spindle if that makes sense

    Its easy. If a "Heavy Ten" it has one of the threads mentioned in my post above. If it has a 1 1/2-8 thread it is not a "Heavy Ten" - but could be a "light Ten" or "10K"

    Serial number right end on top in between two front ways will tell us exactly what it is

    A 199 Z with a 108XXX serial is a 10R from early forties with 1 7/8-8 thread
