I started with a short section of thin walled plastic tube. Probably 5/8 inside diameter or pretty close to that. Drilled a hole large enough to fit the tube in the glider belly, just behind the stick. Drilled the same side hole in a small wood block, maybe 2x2x1. Push the tube through the hole in the wood block and out the belly, and glue the wood block to the floor (below the seat pan). Drill a hole in the seat pan, and trim the tube so that’s it’s flush with the outside of the glider and maybe 1/4 above the seat pan. Now you have a a sturdy channel to route your “pee tube” through. Make sure your “pee tube”is long enough to extend below the glider about 6 or 8 inches. If you don’t extend the far enough below the glider everything you send out will find its way back in via the wheel well, even with the doors closed.
