[SEL] re: Gear making in brief - a question

[F86SABRE]

I would say have a go at it.  It has been my observation that if the teeth 
mesh, when one turns, the other definitely will also.  For the use to which 
it will be put, I doubt that it will make any difference.  You might have to 
make some allowances here and there, but so what?  If it doesn't last too 
long, you still have the cutter, and can make another, trying something else 
to correct where it failed.  Carpe diem!
