Hole Saw or Elevator Bell?

While going on a location scout last weekend at a warehouse on Louisville Road I came across an old toolbox. As any good sound designer would, the first thing I did was run over to it, open it up, and begin playing around with the different tools inside to see if anything made any cool sounds. I was baffled when I heard a screwdriver hit a hole saw... it sounded exactly like an elevator bell! Of course I took out all the different hole saws from the toolbox, whipped out my Zoom recorder and proceeded to record several screwdriver impacts on hole saws of various sizes. Once I was done I threw everything back in the toolbox and closed it only to noticed that the closing latch made an awesome mechanical sound. I had to grab some of those as well! Unfortunately I got so caught up in the moment that I forgot to photograph what I was recording.
