For years, I've used an impact wrench to pull tuning pins, and think it's terrific. Recently, I used it to take out a set of plate screws with an appropriate 3/8" square drive bit (Apex). It worked wonderfully! The screws literally *leaped* out of the pinblock as fast as I could move from one screw to the next. Some of them even jumped clear out of the piano and I had to chase them down. Today, I thought "what the heck", or something along those lines, and used the same bit to drive then back into the new block. I'm sold. I installed all of what looked like at least 900 very shiny plate screws in about 15 or 20 minutes without breaking a sweat or chipping paint. And that was being cautious. Screw heads look good too. This may be something everyone on the planet but me already knew, but if you didn't already, you ought to consider looking into it. Ron N
