Joe, this sounds like quite a contraption. I like the idea that it can do all sorts of drilling away from the bench. But I must admit, I can't even come close to picturing this thing in my head. Any chance of a photo (pic says 1,000 words!)? How does it get out over the piano? Seems to me it either needs to be five-feet long to stradle over the front of the piano, or it needs to have a shelf arrangement that sticks out from the main box on wheels and extends out over the piano. I'm sorry but I just don't seem to have a clue as to the general arrangement here (the "big picture"). Help?!?!
