    How that works

    Lets say the two gears were 14 DP. Lets say they were 27 and 28 tooth respectively. PD on the 27 will be 1.9286 and on the 28 will be 2.000

    Center distance becomes 1.9643 - for...

    For what its worth - the most powerful #3 K&T in 1957 was 30 HP - but the "ram" (fancy overarm) had but 15 for the main

    They had experience with such going way back. Many years ago looked at a 1930 #4 High Power vertical with a 14 foot table and extended saddle with support "rails"

    Unlikely in the extreme. The simple reason for this is production machine tool parts are designed (and processed) for their application. Its not like the maker went down to the gear store to...

    Neat thing about such oldies is you see what you get - honest simple iron - ready to do what it was doing 100 years ago - maybe after some "fixing up" mechanically

    If they are FLAT....

    II made some years ago by getting up a DXF drawing and water jetted some out of 4130N steel sheet of the right thickness for a large Asian lathe

    If you buy a new one maybe it will never miss a beat in 15 years - like mine. The sizeable first cost turns out to be practically nothing spread out over that length of time

    Spec sheet says hole is 1 5/16. 1" pipe is very near to that. Seems doubtful on the MT5 - since it is 1.75 big end - and the spindle nose thread is but 2 1/8 - 8

    Something wrong there with the 21/32 - which is .656"

    You add 2 to the 28 and get 30, and 30 divided by .656 = not quite 46 DP

    An 18DP 28 tooth will be 1.667" OD
