Hello,
Barely daring to admit, but anyway. I was going to screw together two laminated wood beams, but my drill turned out to be too weak. What happened was that a couple of screws got stuck halfway screwed in with broken screw heads. Now I can't screw them in or out. Tips and help are gratefully received. They are a couple of solid brass screws, so they don't break easily. I've tried sawing them off with a jigsaw, clipping them off with pliers, but without success.
