for plans or offsets only s&gs:

was reminded of a few other uses for chopsticks(or pointed thin scrap)while cutting out a few panels last nite.

1/ when cutting the panel away from the base board, i staple the board in place on the table, stapling betw other panel markouts or immediately adjacent the panel to be cut out. i have a back pocket full of chopsticks as i proceed to cut the panel away with the jigsaw or handsaw and every 18in or so along the cut i insert a chopstick under the clamped or stapled board across the kerf line. this way the panel being cut off is fully supported along it's full lenght as i cut along. the pointy chopstick ends easily jam betw the board and table to make a whole series of little cantilevers. the better the clamping/stapling, the better the cantilevers.

2/the other technique is estimating how much of the panel to overhang without cutting the table. with thumb and finger holding a chopstick and overhanging the edge of the panel to be cutoff, push the stick thru yr fingers untill the end passes the cutoff line by say 1/4" (your cutoff will be prob at 1/16"+/- outside)
still holding the chopstick, put the end below the table and push the panel(s) in until the chopstick hits the side of the table. staple in place. do the same for an end.
never have to check under a panel again for how far from the table. pretty easy to decide where the 2 drivers are or pretty easy to leave more leeway if unsure.

maybe have to call them 'shopsticks'
