After becoming a new member here this week and posting about possibly getting a new saw, my 1970s Dremel Moto-Shop 571-5 gave up the ghost this morning! I was working on a project and all of a sudden it started making weird noises and then it stopped. There was a hum coming from the motor. I banged a little on the side and the blade worked a second or so and stopped again while still humming. Doesn't appear to have a reset button anywhere. Guess I'll get a little more serious this weekend about looking for a new saw.
