    Re: Is my old saw worth 'saving'?

    That does appear to be an induction motor and given that it's not a totally enclosed design, there's a decent chance that the problem is nothing more than a dirty centrifugal switch. It's not a difficult job to take the motor apart & check it out. If the switch is okay, then the capacitor would be the next suspect in the line up.

      Take a look at #82. I couldn't find a description for it, but I wondered if it was the same sort of start relay as is used in some bench grinders (instead of a centrifugal switch). Or .... is it the thermal cutout??

        Looks a lot like the motor in my Rockwell Beaver 35090A which is an induction motor. Good motor, if it's the capacitor or dirty switch well worth repairing.

          That got me thinking & I found a better parts diagram online. Part 82 is indeed a start relay. It, along with the start capacitor, overload & switch are all housed in the electrical box. That will make it much easier because the motor will not have to be removed or dismantled.

            That is not unexpected.
            It has served me well.
            Thanks.

              in that case,don’t do it,get a European slider!
              if that seems to much,and if a capacitor is all your saw needs,replace the capacitor
              No new saw.
              Will have to get at the electrical box.
              Thanks.

                I'll have to see about that.
                Saturday is the next shot at it at my son's place.

                      Here's a link to the manual which includes a wiring diagram showing the capacitor. http://vintagemachinery.org/pubs/1141/3207.pdf

                        Well, here are 2 pics of what the inside of the electrical box looks like.

                          OK
                          Thanks for the help, guys.
                          $19.98 later, and a few minutes and then plug it into the wall, and WHIIIIIIIIIR.
                          At least as good as new.

                            Great and 2 cents cheaper than my prediction.
