We have a B&S dividing head, which we bought a while ago. We want to learn to use it, but don't actually need to cut any gears so I'm reluctant to buy specific cutters til we do. They're not cheap, especially if we buy individually. Cheap sets go for about £70, no idea if they are any good - so far, most of our kit has been old, good quality and relatively cheap.
I'm wondering about mounting a steel disc in the chuck and just marking it with a milling cutter at the edge in the correct positions, just to get the idea of locating the cuts. I've watched a few videos on how to make the rotations, and we have three discs to select them.
Does that make sense as a method for learning the tool? Or would we be missing a whole other dimension of gear cutting? (Speed/ feed/ depth, of course.)

I'd appreciate any advice.
Thanks, Chris

Glue a piece of paper to the steel disk and use a sharpie held in the machine's spindle to mark it. If you end up with a 'gear' having 29 1/2 teeth, you know something has gone wrong. Change the paper and try again.

When confident, substitute paper for plywood or MDF and sharpie for something more sharpier.
