As I have a Kibler SMR on order, I mentioned my trepidation at the task to my cousin. I stated he had a Lyman kit that had been in his garage for a few years. He brought the parts. When I letting the barrel I finally realized the standing breach was crooked. Fear of straightening it prompted more wood removal. Finally coming to my senses and bending the tang everything was easier. I hope I am more patient in the future.
I lost found my rarely used side rabbit plane handy.
