Fixing the electric motor.

Have been ripping up oak to laminate the frames and that was going well till the table saw stalled and then refused to start! Was afraid I might have burnt it out as I was working it quite hard.
Took off the two ends to inspect the windings. 


They looked fine and read ok on the metre.
.


Had already tested the capacitor and although the reading was not quite what I had expected it was good enough for it to start so the only thing I could think was that the centrifugal switch was at fault. 


The metre gave an intermittent reading so I cleaned the points but the reading did not improve until I bent the actuating arms to allow the springs to close the points firmly.


With the motor back together it started up cleanly and without hesitation!


 Back in business!
