They say the snow is coming so I dusted off the welder and sorted out the pully/motor arrangements.
The pulley was two pieces so I welded it at the seam, sort of, from the inside. First welding in many years.
Then I held the pulley on the motor with a bolt and adjusted the runout and knocked it straight within a few tries and deposited much welding wire
Tricky welding, gotta focus on the shaft since it is so thick.
It should be mostly braces and alignment from here.
