Cockpit Drain Tube

For months I've been going over different ways to lay up the fiberglass tubes for the cockpit drains.  My original thought was to use the plastic tube from the center if a roll of window tint.  Cut the tube on an angle and tape the angles together at one end to form an elbow .... but how do I get the tube out once I'm finished?  I could pry out the elbow peices but the main tube would take hydraulic pressure.  The other day I came up with what I think is brilliant.  Why not use a thin, cardboard mailer tube from Staples?  So... I bought two of them.  Again, I cut 5 degree angles of the end of the tube and, using Elmer's glue, glued the angles together to form the elbow.  Next I applyed 3 coats of a release agent on the tube.
Yesterday I layed up the first 3 layers of fiberglass.  How come in actuality everything is more difficult then when you go over it in your mind?  Anyway, after a lot of mess I finally got 3 layers on.
Today, after my class I teach, I cleaned up the first layup and sanded it down for the second 3 layers of fiberglass.  Today when much smoother than yesterday.

Here's what I came up with.

 

 

Tomorrow, after it's cured, I'll clean up and trim the ends and fit in place for the port side cockpit drain.
