This afternoon I spent some time working on the gearbox casting. After cleaning it up and drying it off, I started working on a repair on it.
It had one tooth missing on the front between the gates...
I wasn't sure what would be the best way to repair it, so I just dug in and tried something.
First, I drilled and tapped a hole up through the broken surface.
Then, after using a dremel to grind the broken surface back to clean metal, I threaded a #10-24 screw in the hole and cut the head off.
Next, I fired up the tig welder and built the tooth back up using silicon bronze brazing wire.
Finally, I spent about an hour blending the bronze back to something resembling the original shape.
I'm not too displeased with how it turned out, and it should be strong enough with the bolt in the middle of the bronze.
