I'm heading out to work, but here is some data.

I have been working on a gun now for a couple months and almost have it completed. I chose to go with muzzle ferrules and split bands for this one instead of the traditional method. How should I calculate the correct length needed to cut the rubber when I make the bands . . . . use the 3.5/1 ratio and subtract the amount of rubber there would be in the stock . . . . or is there another mothod? Any helpful advice would be great from some of you guys who've made guns with this type of muzzle.

Thank you much! :thumbsup2:

Here's how I would do it. Take the distance from the ferrule to the sharkfin, then subtract the distance for the wishbone at the sharkfin (including the part of the wishbone in the rubber). Then subtract the line from the ferrule to the band (including the line in the band). This is the stretched length of the bands. Divide this length by 3.5 and you have the unstretched length. Add back the length of band at each end for covering the line and wishbone, and you have the length to make the band for a 3.5 ratio (25% elongation).

Cut them on the long side. Reduce length if needed.

I'm not a typing critique, but 25% elongation won't fly around my house.:laughing:
Who says '' specimen length'' shouldn't count for something...... OK I suck at nerd humor.;)

I like to stretch my rubber Specimen L X 3:thumbsup2:

Picky, picky, picky! It's more of a challenge with only 25% elongation- you have to get the fish to swim directly at you really fast! :laughing3:
