after pull'n most of my hair out, on makin butt cap for a wooden sliding patch box lid, i can now pull the rest out now on a catch fer the *&$@#* thing. hard to figure this out, when i made several others before. i guess old age and hip surgery, grand kids hollering and things fall'n on the floor that ya constantly pick up or lay down on the bench, than your hair falls in your eyes, and smash a finger. DARN, i just love building black powder rifles. if any of you fellers have ideas on catchs it please pass it along, something different please.
