Glasair Elevator Internal Arm Counterweight


This builder hint was John Schroeder. The procedures were used on a Glasair Super IIS FT


In step 2N7, the process starts by cutting the lead sheet in several pieces (1.5″ x 5″) to make a weight. The amount of weight is calculated by taking 60% of the total moment from step 2N5 and dividing that figure by the moment arm of 9.5 inches. You are then directed to bolt the pieces to the internal counterweight arm, evenly distributed on both sides of the arm. I did this and had 6 pieces on each side. I could not get the washer on under the nut and with just the nut, there was only 1 thread showing. In addition, the whole thing looked bad!
