Nice gears Gail. Chris the diagram I use for all bevel gears starts the same way draw a rectangle using the number of teeth for the sides. The diagonals are the pitch line. This works for both parallel depth and true bevel gears.Dan

Chris,I use a book called "Gear Design Simplified", it has the formulas I use. It also stated that the face length should not be longer than 1/3 of the theoretical pitch cone. That is a modern rule and does not apply to historic gears like Shay gears.Dan
