85vette (Brad) send me a really cool idea. At least on my new Sterns, the stand up targets tend to move side to side and become misaligned. I took his idea and made what I call a 'splint'. After a very quick disassembly of the target, the 3 parts slide very tightly into the splint. The splint minimizes the movement of the target. It takes less than 10 minutes per target to install.
The problem to be solved here is that the holes in the switch is a plastic tube so not to short out the switch. The tube is bigger than the screw so it moves within the tube. The splint uses the playfield bracket to not allow the switch to move side to side. It is a box design so not to allow flexing.
He is doing testing and I have them installed on Metallica and ACDC. If it works I will compile a list of all the games this goes on.
