Bill, Scott, I have one of the "jigsaw" machines that uses the jeweler's blades. Bought it from Micro Mark and used it to do the piercing work on the scroll overlay on my Model A steering wheel. That was in 1/16 in. aluminum. Worked great and solved my problem of holding the saw vertical. I always seemed to get slanting cuts that gave me problems. As I recall, the price was about $150.
