Re: Dunlop Strap Lock Situation
Something else you could do but would be trickier would to drill a hole into the screw until the screw no longer can hold the button, take the button off, and then use a vise grip to grab onto the screw and turn it out.
Or if you can, just get it loose enough that you have a few millimeters between the button and wood, so the screw is exposed alone. Clip the screw with heavy duty wire cutters, and with the remaining part of the screw sticking out, vise grip it and turn it out. If there isn't enough to grip, you can drill a hole slightly bigger than the screw right where the screw it, basically drilling out the screw with the wood, and then fill it with wood filler + toothpicks so you can get the same size screw and it'll be snug, or even tighter.
