I measured (with my "hi-tech" jig) So pardon the glaring problems here- everything is measured to the 1/8 inch- here is a shot of my measuring jig:
Just 2 framing squares- line up the same measure on each leg and "poof"... Now THATS science...ish
Went through ALL the gears in the box and found/grouped the ones that meshed together first- Then did tooth counts and major diameter measures.
There is more here than initially thought. there are several different "groups" of gearing- I divided them by which ones meshed together (But I have no ideas on pressure angles or PD as of yet- so bear with me...
Here are the "original" gears (Double keyed) laid out- measurements to follow
(GOING RIGHT TO LEFT)
More to come-
