Man I knew that the chum stick comment would get some of you guys going!! Yes they are the ones that the boys from Salmon University are going to, or already are selling. I made my own a few weeks ago when a friend of mine showed them to me. He had gone to a S.U. seminar and they had them there. So I just copied his proto type. I like to think I made a better model than his. Sorry P.J. You just have to accept that carpenters are better at building things than electricians.I made mine with open cell foam inside that holds the scent. But as soon as I can lay my hands on the pellets, thats what I'll be using.
I made them out of 3/4" electrical PVC with a capped end and a threaded end so you can access the tube. Perferated the tube by way of drill motor. A simple eye bolt and a little imagination for attaching to your DR ball and you're set to go. No I just need to get one of those wind up toys. ( Black Box )
