Computers turning your pallets for you??
Ha!
used to work it all out with squared graph-paper & a ruler & pencil.
Then stand in the driving rain & sleet & man-handle the built pallet around & over the in-door ball-mat ( 25% of the balls missing, 25% permanently jammed and 25% damn near rectangular). extra points if you manage to get the pallet run over your foot.
wet & cold, but were we miserable?
yes, of course we flaming were!
