stacked gears for quick change gearbox

thingiverse

if you have an old imperial hobby sized lathe and would like to make either a light duty gearbox or make castings for metal gears then these along with a few of the original sizes will be handy to have about, the original designer supplied the gear set as individual gears to my specs and ive combined the gears to make the compounds here to make life easier for everyone else, check his thing out you will need a couple of other bits from his design and if you want the rest of the information the article im using as a guide is http://vintagemachinery.org/pubs/51/7158.pdf edited to add better version of the 32/16 gear as i found the original almost impossible to print with my set up, the gears have already been scaled so they can be printed in mm rather than inches, and i know the 36 gear tooth shape is wrong; i intend on running it in on a steel gear of the right tooth shape so it heats up and melts to the right shape.
