I was wondering what glue you guys used to attach your bellows? Every squirrel call I've made so far I've used goop on and so far they are doing good, but when people grab the squirrel call and try to use it , generally it resembles a big dog shaking a bone, rather than just tapping it for some reason they feel the need to pull twist slam bend shake squeeze and any thing else you can imagine...... Makes me nervous, has anyone had issues with this before?
