Decide on the rotation that you require
[Left hand or Right hand] and the pitch
that you require. Select the gear set that
is required for your job from the gear
selection on the inside of the door.
Note. There is an extra gear in the right
hand spiral. This is used to reverse the
rotation.
Note. The center part of the gear
diagram represents the gear arm.
Note. Gears B and C fit onto the same
shaft, which rotates both gears at the
same time. All other gears fit onto a
single shaft
Note. The top gear numbered 96
[number of teeth] is the gear that is
permanently fitted to the lathe spindle
and the gear train engages with.
