    Very particular. Brochure has interesting statements - if one happens to have this head (K&T had NUMEROUS vertical heads)

    Its HELICAL, meaning it is made for the mating gear housed in the head

    The V Head has the same speeds as the machine - meaning the head and its pair of HELICAL gears and pair of SPIRAL BEVELS provides an overall gear ratio of 1:1

    You will also need the center distance head gear to spindle gear - in case the spiral bevels inside are not one to one - then the helicals won't be one to one either

    Yes that’s why I hoped someone on here had one. And could tell me the amount of teeth.
    It’s always easier to be told than working it out!4a151b93-f67d-447c-bdb3-a1471ae7f003.jpg

    Is this one like the brochure and partially supported by dovetail? If so, you have some nice datums to measure from

    FWIW, a number 2 drive gear is 5.3" OD, has 28 teeth and is 1.5" wide.
    The back of the gear is 1.4" from the column face.
    The driven gear is about 3.7" OD and has 19 teeth.
    Hope this helps.
