I'm just glad you got me motivated to play around with this because I finally have a use for all these small pvc sections I have layin around. I run a custom fly rod business and I ship all my rods to my customers in pvc tubes for protection during shipping. So needless to say I have tons of 6" to 2' long sections of pvc left over that I have had no use for....until now lol
Soon as I get some more time I want to do one with a Y piece of pvc where there are two opening on one end. I think that would be neat.
