I just did “a thing” ... could be helpful to others.
You know how those crappy Stern plastic lane guides are always busted up?
I made some overlays out of high impact acrylic to go over the top. Now the ball runs nice and true, and what’s left of the lane guide is protected.
My left one was ok, but the right one was busted. I have now glued the broken bit under the new clear acrylic, just for decoration purposes. (That’s where the red tape is in the final picture)
Easy to do ...
1/ scab some scrap acrylic off your mate
2/ trace out the outline of the guide on it
3/ cut with bandsaw or jigsaw
4/ machine back to size with belt sander
5/ smooth out edges with orbital
6/ line up holes and drill them
7/ screw em on
