bucksaw wroteI think I would have drilled in from the back side and punched it out. Not sure if if would have worked. But in my head, it's a great idea. Looks like aluminum.
Based on part geometry, drilling from the backside would be tricky due to the angular surfaces of both the back end where you'd start the hole, and then drilling into the mounting holes 41°]only[/B] remembers failures.
Even though the attempt failed, I think it was a good logical starting point. Logical and failed in the same sentence???? :eek: I'm OK with that. As I look at the piece today with lower blood pressure and calmer thoughts, I think it's still fixable.
Plan of action is.....drill through the
center of the button and remainder of part with a small pilot hole being real cautious when I get to the mounting hole countersunk surface. I'll put a center punch dimple on the countersunk surface for the drill to locate on and continue through the part. Then come in through the backside with a slightly larger bit stopping when I get to the beginning of the button hole . Then insert an appropriate sized dowel pin to butt up against the back of the button and then smash the beejeezes out of in with a 12 lb sledgehammer (or a small ball peen hammer, which ever is closer). If all successful, JB Weld to hide the evidence, slap on a coat of primer, hammered paint, badda-bing, badda bang, Houston, we have a functional miter gage indicator!!
Sound like a plan??
