Default Gear cutting

I am working with a group of students who have been assigned a set of gears to be constructed out of wood. I am looking for hints that will assist them in understanding how and why jigs work better than freehand cutting.

Gear template generator

Joe,

The first advantage of templates or jigs work better than freehanding is repeatability.

Once you create a master template, you can accurately copy it much quicker (and using much less skill) than free handing.

Using a jig also introduces accuracy. If you were to use an indexing jig or a dividing head, you could space your gears accurately, whereas freehand could cause some errors that would prevent proper meshing of gears.

just a couple of thoughts,

Doug
