Pulled the motor out again this evening - a 5 minute job. How cool is that?

Started working on the field polarity switch. Not a 5 minute job.

It's a conceptually simple task, but had to run around borrowing tools - first a honking soldering iron which wouldn't do it, then a torch set - to de-solder two connections, blah blah blah. It took a long time, and we didn't get it finished. But should be done tomorrow.

Then we reassemble and test the "new" CCW motor RPM against "stock" CW RPM of sister motor - to determine if the brushes are neutral or not. Hoping they are (it'll save time). Should have compared RPM of both motors in stock form before all this, but I wasn't being very scientific.
