Made a gear cutter from scrap

[alb]

Thanks for the info
The gear I was making is just for my lathe so I can do some thread cutting.
The tool is cobalt so very hard but I am only going to cut nylon,plastic and brass gears so abut over kill

Nice job cutting the gear. Gears are a lot of fun.

Making a hob is another way to do it that closely replicates an involute gear form. Here's a link:

Nice job.
Another way of making a cutter is to turn the profile on a piece of silver steel then halve it and harden it like this.


Its easy and works well.

I will be in St Andrews for a holiday and to see the family next week, so dont use up all the sunshine.
