Here is an example for F1L.

Find the loop length that you want. Cut a bit of rubber to be the length plus 2 inches.

i.e. 14" loop, cut (14+1)*2 = 30 inch length = 15" doubled.


Measure the width of the rubber with micrometer - i.e. 0.128"

Weigh the length of rubber. i.e. 2.54 grams.

You decide you want the rubber to weight 1 gram exactly.

Here is the math:

1/2.54 * (15/14) * 0.128 = .05399

Strip it to 0.054" and you when you tie off a 14" loop it should be precisely 1 gram.
 

I set up the spreadsheet to have only 1" additional length, but the math above is the same.

If anyone has problems with this, I will define variables and post the math that way.

Regards.
