Elliptical Magneto Gears
Posted: Wed Dec 30, 2015 9:11 am
Miniature Magneto's for small model engines are difficult to build!
I used Gearotic to make the magneto spin 3x crank speed(at the critical point)
for a hit and miss engine. These gears are .25" thick
aluminum and Delrin. Gears are 2.050" between centers. Big teeth because
I limited the cutter to .094. No high speed spindle.
Bosses were added for a 1/2" crank boss and a points cam . 8)
Thanks Art!
