Unmarked tool

I seem to recall this by a trade name...G10? Is that correct or am I misremembering?

I remember when I was a kid building RC pan cars, we would by a sheet of G10 and carve our our custom chassis with scroll saws.

G10 is also used for knife scales.

those are worth some money I would love to get one but they cost too much and I dont deal with gears that often

Machined a ton of phenolic. Made many brush holder bases for large DC motors. Always had a shop-vac near by!

I think phenolic and G10 are two different things.

From Wikipedia: G-10 is a high-pressure fiberglass laminate, a type of composite material. It is created by stacking multiple layers of glass cloth, soaked in epoxy resin, and by compressing the resulting material under heat until the epoxy cures. It is manufactured in flat sheets, most often a few millimeters thick.

G10 = Fiberglass + Epoxy resin
G3 = Fiberglass + Phenolic resin
Phenolic = "canvas or linen or paper impregnated with phenolic resin" per benmychree

I got 5 of these, no markings.

It's wild that the gear teeth aren't identified. I could understand a decal disintegrating from one piece, but 5? Maybe liberated from the production line?

I guess, sit down with calipers, Machinery's Handbook and a pot of coffee.............

I've never been able to distinguish the Pressure Angle of a gear by using a gage that mates with the sample. I guess I would need some training.
