Joe, I think it is really neat that you were asked to do a demostration of the scroll saw. Don't see those any more. At one time, years ago, you could attend home shows where there may be a demostartion of scroll saws, mosthly I remember seeing RBI having a booth. I recall too once seeing a scroll saw demo at a lunber yard. Even craft fairs would have 2 or 3 scroll saw booths set up. Don't see those anymore. Anyway, to cut a long story short, that is how I became interested in scroll sawing. Needless to say, my first scroll saw was a RBI because that is mostly saw.
