How to repair a broken band.

When speargun bands fail "prematurely" - one side of the band breaks just above the wishbone, and the rest of the band is in great shape. Don’t replace the whole band, heres a way to save the band:

Here's what to do:

1. Remove the remaining broken rubber & ring from the wishbone. It's easy to crush metal rings with pliers, otherwise you'll have to improvise.

2. Cut a little bit of the broken band to make the end "nice".

3. Moisten the inside of the band with a little spit or water & push it back on the wishbone. Push it all the way up to the bend.

4. There are many variations to this next step, but I'll stick with the earsiest.
Using waxed twine (or electrician's twine) tie an overhand knot with 4 twists in it (4 times through) about 1/2 inch from the end of the band. Pull this tight, then turn the band over and tie another 4 times through overhand knot. Pull tight, then cut the twine near the band. Slide the now mended band up tight against the wishbone stop and you're done!
