Got a call from Robert.Thanks
He said it looked pretty close and suggested propping some thin plywood underneath and using a slapper on the remaining high spots (previously marked with a pencil squiggle.)
Tried that and am getting closer with a little more judicious shrinking with the donut dolly. Now have just two light oil cans that are smaller than the previous. It's been a slow process. Kind of hard to see the marks on the photos and to get the 2x4 propped in the right spot underneath.
