Just noticed a few drops of water dripping off my Neilpryde wing to fuselarge joint after assembly before going out for a surf.
Obviously the heating of the sun helps to push the water out.
So after my surf I disassembled the wing & noticed only small drops of water coming out of the trailing edge and not the joint.
I then noticed that the surface of the recess at the trailing edge bolt hole is probably cracked due to its angle not being an exact fit.
So I have come to the conclusion that when the wing is tightened down it opens up the crack & squeezes the water out.
Also the pressure of tightening the lee side bolt has added extra pressure that may have slightly split the lee side edge hence the small droplets of water exiting it.
Looks like I will dig out the crack to open it up a bit to help drain the water. Then tighten it against the fuselarge to check if any more water drains. And then will epoxy over the crack & either the trailing edge or entire wing. Probably the entire wing.
So in future I think it is ok to tighten the leeding two bolts as normal with the T wrench. But only tighten the trailing edge bolt with a normal screw driver with the posi drive.
I have been conscious of never overtightening the wings due to their construction compared to the mast whichis tightened the most.
Never had a problem with disassembling.
