Ray Milligan has a book out with step by step instructions on 4 coiling #3s
It's called coyote fever , when I find mine again I'll give you his # . When 4 coiling replace the regular spring pin with 5/32s I'm not shure , and use 1.75 coils on the off side.. I think Milligan has an ad in t&pc I'll check..
Good luck LIL JOE
