Diet plan for skymasters?

[JAG]

Some great advice here already. The only thing to add, is sometimes the scale error (if you weigh) can also add some weight. Last time I weighed an aircraft at a shop (part 145 authorized Cessna Service Center), we went through 3 sets of calibrated scales until we found ones that were accurate (at least to my liking). It was quite interesting to see the difference in weight between these calibrated electronic scales.

My '66 was never weighed at the factory - the weight was calculated.
