Anyone can build a gearbox without expensive machine equipment! Just takes a little time
and some patience. You will need a digital caliper some math and drill press and some hand tools.
Take your alum tube spray it with blue layout dye or paint will work. Lock your caliper at desired
Distance (.500 in this case) uses one tip on edge of tube and drag other along length to make centerline.
Decide where you want rear axle to be and center punch it with fine centerpunch. Next comes the fun
Part MATH (very easy)
C= n+N C -center distance between gears
2P n-number of teeth on pinion
N-number of teeth on spur gear
2P-2 multiply the pitch (32)
14+72 divided by 2x32=1.343 inches
Now lock your digital caliper @ 1.343 this will give you zero clearance between the gears but I have found That with a little play in bearings and shafts this will be a perfect mesh! Place one tip in rear axle centerpunch Hole a then drag other tip across the centerline in a small arc. Carefully centerpunch the intersection ofThese two lines! See pic
Layout All your shaft holes this way before any drilling begins!
