I looked at the pics real quick but I’ll have to sit down after work and read the thread. I’m not familiar with that system of filing a chain. I’ve seen pictures of those setups but never used one. Guess it time to learn! LolYou can start here and/or skip to Post#60 which actually has a machinist drawing but without dimension. What he shows is exactly what I need made and I'm golden.

I can't find pics of the unit the machinist did.....I think Philbert linked me to that.
