Travis, could you send me the info on your tube also?
"Just doesn't sound right"
Fellas I was thinking 3" to 4" long mouth piece with a tenon which you could slide tube on! and a 1" cap with tenon. You could have a cover made from burlap or another meterial other then camo, to stand out. If you really wanted to make their jaws drop you could use leather cord with slip knots to attach your cover and drop a set of ivories from the cord! This may be over the top but it would look pretty cool.
I don't think this has been done before?
