Jaguarguy Posted November 5, 2021 Report Share Posted November 5, 2021 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. OCtoolguy and Wichman 2 Quote Link to comment Share on other sites More sharing options...

Or make some. I'll bet that's what is wrong. Woodrush, WayneMahler and Wichman 3 Quote Link to comment Share on other sites More sharing options...
Dak0ta52 Posted November 5, 2021 Report Share Posted November 5, 2021 Ditto on what Ray said. I had one quit and contacted Dremel. They actually sent me a set for my Dremel model free of charge. I say I had one... that is until the wife claimed it as a nail file for the dogs. Bought me a new on and let her keep that one.

He's talking about a scroll saw. Jaguarguy 1 Quote Link to comment Share on other sites More sharing options...
Scrappile Posted November 5, 2021 Report Share Posted November 5, 2021 Well,, they may do the same for their scroll saw... brushes are an expendable item... WayneMahler and OCtoolguy 2 Quote Link to comment Share on other sites More sharing options...

The bushings I had replaced were on a rotary tool but hopefully Dremel will be kind enough to send him bushings for his scroll saw as they were for sending me the bushings for the rotary tool. Sorry for the confusion. OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
Jaguarguy Posted November 6, 2021 Author Report Share Posted November 6, 2021 I've been looking for schematics and parts for the 751-5 - can't find any on the internet. Will have to breakdown and try to call them on Monday. Thanks for all the suggestions. BTW - I found a new, unused WEN 3921 for $70 - going to pick it up tomorrow.

Not sure whether you just made a typo here or in your search. It's a 571-5 and I found lots of parts diagrams for it. The brushes seem to be encased inside of a plastic housing that covers the motor and houses the electricals.

Yes - I gave it away for free this afternoon as a "project" to the new owner. OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
