I t helps to counter sink the spring into the plunger hole. I chuck the counter sink in a tap handle and counter sink the springy by hand
Shooting off the shelf does not give me the best results in a crawl. Proves not too forgiving. Springy rest and string walking are partners to me. There is a downward vector of the spring on release. The rebounding spring is part of the crawl. For some reason this makes the springy more forgiving. I have noticed a difference in the stiffness of various magnet flippers. Some flippers more forgiving than others.Nice work Rusty. That spring fits right in there. How did the tune change going from the shelf to the adjustable springy?
