Title: The Water Tight Integrity of the Vessel Has Been Violated
Post by: 2051476 on June 04, 2013, 02:27:02 PM
 After untold hours of work I took by Robbe U-47 to the water tank to test for leaks and start the trimming.
Good news is all the rear bulkhead fittings for propeller shafts and servo leads are water tight.
Now for the problem.  I used the bayonet system from Norbert Broggen. I installed as stated, rough up the Robbe Tube and the bayonet with 80 grid sand paper. Wrapped with the fiber glass tape which was provided and used marine epoxy. Now when I put pressure in the tech tray tube it appears I have a leak somewhere in the fiber glass epoxy area can't really pin point. I was thinking of running thin CA glue on the inside where the tube meets the aluminum bayonet locking male assembly.
Anyone have any better ideas or just any direction would be appreciated.John

i would run some marine epoxy around the inside of the join you will need to do it about an inch at a time otherwise it will end up all on one side (don't ask how i know  :embarrassed: )

When I had my full size boat mysterious minor leaks could be effectively cured with this stuff: http://www.captaintolley.com/ (http://www.captaintolley.com/) it is a very thin resin which works its way into cracks and then sets hard.
