this is closely realted to another thread and i didn`t want to hijack it.
i would like to try making a gear hob, have a 9" model A , would like to make hobs in 16,18,20 DP, all 14.5 PA.
i need to figure out what gearing combo will give a lead of .1963" (16 DP, very close to 5 tpi) , a lead of .1745" ( 18 DP ), and a lead of .1571 ( 20 DP )
i can make different stud gears easily enough, i just don`t know how to figure what ones to make.
i think my brain exploded.
