Description

As seen in the December 2017 Model Aviation, these brass reference weights eliminate nearly all calculations previously needed when grading your balsa supply with a digital scale. Easily “reprogram” your digital scale to display balsa density instead of ounces or grams. Sort your balsa faster, and avoid errors from misreading look-up tables.
Designed for use with full sheets 1/32 to 1/4 inch thick, measuring 3×36, 4×36 and 3×48 inches.
Includes five brass reference weights and laser-engraved storage tray.
Requires a digital scale with 50-unit counting function. Scale not included.
