I tried that did not even think about using DW scale. Picked on up at Goodwill for $3...It worked but the scale will never be the same... I would love to have a Sherline..
Might try this on mine to check the tongue weight, would two 2 x 4 blocks of wood work on this? DW said for me not to break her scales...
Ideally, you should have 2x4s with notches cut out for the pipe both on the ground, and on the scales.....this would prevent the pipes from rolling, in addition the scale 2x4 on the scale would better distribute the weight, so that you would not "crease" the scales.
