Some pictures of gear cutting tool, FINISH !
During gear cutting, I adjust the height .... so the gear is not good enough. It's just a test gear (gear made of aluminum)

That gear looks like it might be good enough to use. I've used aluminium for cam/crank gears on hit and miss engines with no problems. Might be a little better to make the crank gear out of brass though.

I recommend locking the shaft instead of locking only with the locking pin on the gearwheel as the indexing disc. This is to prevent the gearwheel from turning out of position during milling. Then you get better teeth profiles on the machined gearwheel.

Nice job - looks like they mesh very well.
