I'm not a call maker . But ,I do dabble at times . I have built 3 wingbones . After cleaning and bleaching the bones , I allowed them to dry for a couple days , in the truck cab , with the windows up . I then glued them together with ELMERS CARPENTER glue . I've been told that this glue will not stand up to the weather . Well, I keep it inside my shirt when I'm hunting . Any other time it's in the house or truck . Two were made 3 years ago , and the other , just over a year ago. I handle this one every day . Lately it stays by the computer where I can practice with it between posts and forums . The Elmers glue matches the bone color nearly perfect. None of the 3 calls have shown any sign of weakness , cracking or separation .
