a simple button actuator.JPG
this is what my simple mind see's, it can reverse right or left. rod guide on button side could sit lower, so the button can hang down a little lower than the cartoon shows. the button box shallow so it isnt a huge step from the machines button to the cross-side actuator button.
across the distance (20" about), a little un-parallel wouldnt be a huge issue if the rod guide has some clearance. at the receiving end a wingnut adjusts length, a pin adjusts "teeter-totter" cantilever for different machine button height. the pad right of the suction cup keeping the inverted L shaped body tight to the side of the machine, with the line of the rod itself keeping it all straight.
this just "chicken-scratch" diagram yup.. but you can maybe see the potential for two units, one to make magna-save available for the opposite side. if the spot below where the rod's wingnut is were hinge pinned the action might be a little lighter, or if the pushrod is small enough diameter it'd be able to flex a little while still being strong enough to push the flipper button through the cantilever..
(1/16 or 3/32 maybe?)
dont get me wrong, Ben's plenty cool! he mightta overcomplicated a GREAT idea, or maybe I oversimplified? if a one handed person were playing against someone, there should be room to easily pop it forward-away an inch from the button itself. the actuator button right over the machine's button shouldnt be a problem.
