Quoted from scottacus:...
My big idea was to make a mounting plate/disk that all of these components mount to and then use a couple of screw slots that will allow rotation of the plate (with coil mount, ball saucer and arm mech) and a third screw hole to lock the plate in place once the shot is tuned. I'll have to take a look to see if I have the real estate to make this work but if so, this will be a game changer (literally).
Instead of a boring screw to lock it in place go all-the-way-out-crazy and have a controlled motor rotate the kick-out angle (random angle or angle set by current scoring/rule in effect); daum that would be aswesome sauce!
