Today I've been looking through my boxes of gearboxes and decided to label up the boxes for future reference. Ive been looking at stickys book and the references made to loose gears in respect of measurements of pitches etc, so i got my vernia gauge out and started measuring only to find most didn't come close to the figures in the book.
Ok so I've counted the teeth and matched the loose gears that way but the measurements through me out at some point.
Could someone explain to me where i measure the distance from to match the book reference also some loose gears have same teeth but different pitch, would these be compatible across the range if used in conjunction with the similar gears.
thanks in advance.
