Joe and I discussed this a little via email. I'm going to say oil, check the pedal adjustment and a drop or two of oil (I know some like engine oil, I usually drop 2 drops of triflow) onto the bearing below the worm gear on the motor and run the daylights out of it. This is also pretty much in keeping with what you found, right Joe?
Awww, thanks Miriam.
If you've watched my videos, you know most of what I do is stream of consciousness. If I'm having a good day - it can be pretty coherent.
I hadn't heard about Kathy... that's a shame. She sure does know a lot but I certainly wouldn't call her a know it all, not in the tone of voice it was likely meant in. Some people really are knuckle draggers!
