Acrylic Mirror Blades
One of the mods worth making more of and selling are my mirror blades made from 1/16" mirrored acrylic. Selling would help me recoup the cost spent on material.
I am not sure of other Stern tables but mine has very tight clearance from the playfield to the side walls. To protect the blades from the playfield scratching them I designed my own version of Blade Protectors out of very thin Styrene which holds it folded shape pretty well. The protectors included will not have that orange tape, I just put it on to see how it looked.
I designed my mirror blades to cover the backbox hinge when mounted to have a better final look. I don't plan on removing my backbox anyway and doesn't effect folding the backbox. Cutting a hole could be an option.
I also am using 3M double sided tape to mount them as well. Using the screw method on the bottom like other blades didn't work well with acrylic.
