I took time off from the drudgery of rebuilding my 10EE to do something I enjoy: making gears. I looked at all the pitches capable on the gearbox and realized that two stud gears, a 45 and 50, will provide essentially every useful pitch, save one, .8 mm. So instead of duplicating every stud gear that Monarch and ZK offer, I only made the 45 and 50 right now. I can always make another stud if I need. The gears are helical because I got a brand new,super fine quality Class AA Gleason hob off ebay for only $25 that fits my Barber Colman #3, but it is a wacky pitch, 34.05 Dp, slightly smaller than the standard 32 pitch for the change gears. Obviously, except for the original purchaser of the hob, there isn't much demand for a 34.05 Dp hob. By making the gears helical the diameter of the gears enlarges based on the helix angle. I simply duplicated the diameter of the 32 Dp gears.
I made two sets, one for me and one for EverettEngineer, since he was nice enough to give me the massive T5 transformer to use with my Parker drive. The crazy thing about gears is that each set of 3 gears is less than $10 of 12L14, but as ZK and I point out, gears are an expensive hobby. A gear shop would charge upwards of $1000 for these three gears.
