Well i did not think about this pin I found being hardened. Went to drill for the split pin and the bit just stopped :/
Luckily I had two carbide 3/16 end mills. Both of which sacrificed themselves to the operation, they bored through ok, but when they hit the opposite side they didn’t like that hardened layer.
Oddly they drilled a hole slightly larger then 3/16 as the pins were a hair loose.
Luckily my last auction score of a only toolmakers box had some shim stock.
Added a little strip and she’s golden.
Heated an bent the tooth back. Waiting to cool and I’ll file and clean it up.
