How to Calculate Amount Required
To calculate the amount of rib stitch tape required you will need to know the total length of wing and tail cord inches.
1. Count your wing ribs and tail ribs that will be rib stitched and double that amount since both sides will be rib stitched
Sample: 24 wing ribs x 2 = 48.
2. Multiply your cord length by your total doubled rib quantity.
Sample: 18" rib cord x 48 = 864 ".
3. Take the measurement of the rib stitch width you will use and divide that into 2 inches to find the amount of strips you will get from one 2" x 36" rib stitch tape strip.
Sample" 2" divided by .125 (1/8") = 16ea 1/8" x 36" strips.
4. To find the total amount of 1/8" wide strips you will need, divide the number of strips you got from one 2" x 36" strip into your total cord inches, then divide that by 36".
Sample: 864" divided by 16ea 1/8" strips = 54
54 divided by 36" (rib stitch tape length) = 1.5
You would need 1.5ea (2" x 36") rib stitch tape strips.
