Spreading Board

The 3/16” pinning strip is rigidly placed, allowing the pin to be positioned at any point along the shaft by pinning entirely through the balsa strip. The vertex is located so that sufficient clearance permits mounting the insect at the top third of the pin. A 1/8” hardboard floor under the board prevents accidental disturbance of pinned insects from the bottom. Groove is adjustable 0 to 13/16”. Board is 5-1/2” x 14”.
