Last year I purchased a T.R.U. Ball Release. In a word, I love it. However, I didn’t really like the V-Lock wrist strap option (http://truball.com/V-lock.html) so I decided to make my own.
I found one of those Croakies(R) sunglasses straps in one of my miscellaneous gear bins. It is made from a high-quality braided cordage and had a slip-adjuster already in place. Perfect!
After shooting a few arrows and examining my form in a mirror, I figured out that the strap should connect to the body of the release at a point about 1″ to the outboard side of the caliper axis centerline.
I simply drilled a hole and countersinked both sides to eliminate sharp edges and reduce wear on the cord. Then I threaded the cord through the hole and melted the end to the point where a molten blob formed. Next I pressed the end against the metal table of my bandsaw to flatten it, creating a hard “stop” to keep the cord from pulling back through.
Done deal – bare bones simple and it works great! (click on photos to enlarge)
