back gear broken tooth
Hi
My ( 9 hercus / sheraton ) back gear had a broken tooth . I built up a new tooth with weld and hand filed it to shape, this repair has lasted 3 years but it has broken again .
I am thinking of tapping holes into the broken tooth base and then screwing in a couple of small studs, then brazing around the studs to build it up , then re cut the new shape with a proper gear cutter .
Can somebody tell me the correct PA of the tooth , and what size gear cutter I need to buy ? Mike

Should you be working out what is causing the breakage first.
Did it break due to a bad repair?
Did it break due to operator error?
Is some thing not meshing correctly?
Did it break whilst in use or when removing/fitting a chuck etc.
Replacing the damaged area with steel could possibly transfer the cause somewhere else.
Cutters are 16DP.
PA is 20 degrees
Cutters required No2 and No5.
