It's not that expensive: https://www.wabeco-remscheid.de/keil...adeln-hss.html

You also need some kind of arbor press to push the tool through the gear.

If you have a lathe can also make channels for braces, I do not believe it was possible, but I ended up witnessing with my own eyes the operator making the key a pulley / shaft

Just make a tool in the channel width and entering decimal measures to the channel.

Note:. Power off.

If I remember correct I have made keyways with lathe at school many years ago.
I do have a lathe, but those keys I use are only 2mm thick and I'm not sure how well a self made high speed steel tool might last on that.
But anyway with bigger ones it does work

Slow progress, but I got something done with the tipping cylinders
