In a bold and foolish move this morning, I simply plugged in the frayed off-line power cord into the Flexo and outlet, and flipped the switch. Motor spun, no work. Tilted down the keyboard lookup table (sic) on the bottom, rotated the mainshaft by hand, it loosened. After that, the thing ran! Lubrication is dead, which was obvious before I started. I know I shouldn't have done this, but total run time << 60 seconds, it was a 'success experience' and overall good news. It was nice to have a physical experience after all this time of hypotheticals and document-gathering.
