I'm sure everyone is familiar with how side rails are attached on modern Stern games. I have an RBION which has the usual wear around the flipper buttons, so I decided to get new lollipop side rails and just cover up the worn paint around the flipper buttons. 2 round head bolts on each side, 2 screws on the outside holding the existing rails in, should be a piece of cake!
The right side rail has a bolt that someone tightened so much that the nut is literally embedded into the wood. The top half of the nut is exposed, but it's not enough to be able to grab it with a wrench or pliers or anything.
What's the best way to go about getting this out without extensive cabinet damage? My first instinct was to just gouge the wood around the bottom half of the nut to give me enough room to get a wrench on it to free it up. That could be covered up with a washer under the nut, but obviously it would be damage that I would have incurred willingly (and would render this game incapable of ever being considered imamaculate). Any suggestions for doing this without any damage to the cabinet?
