It was still making a racket, so we took it apart again and tweaked it.  It’s quiet(er) again, but it doesn’t have enough torque- when I throw big I can feel it slowing down, and I can actually grab the wheel and stop it, so I’m now officially in the market for a new wheel.  Thank God for holiday orders!  At least I can still work on my existing limping-along old wheel in the meantime.
