The gear that stood on the electric motor of the vacuum cleaner was plastic. Her teeth were worn out, licked by the drive belt.
I decided to make a bronze gear. I decided to hollow out the gear tooth cavities on a JMD-1 milling machine.
The profile of the gear is not involute, but closer to the circle. And on the drive belt, the tooth profile is in the form of a trapezoid.
I decided to make a radius cutter, with a radius profile. Turned it out of the end mill.
On this JMD-1 machine, I have already done chiselling with homemade chisels more than once. He hollowed out four- and pentagonal holes, made grooves for the dowels.
This is shown in my videos on my channel.

To prevent the cutter from turning during chiselling, I fixed the spindle relative to the machine quill using a homemade mandrel. How I made it is shown in my video:

This gear has 10 teeth. Therefore, when chiselling, it was necessary to rotate it by 36 degrees.
Turned with a homemade rotary dividing device. How I made it is shown in my video:

It shows in detail how I made a new gear.
Pressed the gear onto the motor shaft.
The vacuum cleaner works well.
This is how you can make a gear by chiselling.
