[Rhodes22-list] CB Cleat - strong, permanent fix in blind space

[mputnam1 at aol.com]

Robert, this may be a dumb question, but what happens to the string?  Once you start putting the epoxy-fiber filler in place, do you cut the string off?  Or keep pulling up the piece of wood and fill around the string and then cut the string? (which would seem to leave a small hole)
 
Thanks,
 
- Mark

Slim, I'm not sure of the exact situation that you describe,
but the following is a generic fix that you can adapt to
your circumstances.

The attached drawings show one method of dealing with a cleat 
whose screws have pulled out of a fiberglass surface where the 
open space under that surface is not easily accessible.

Drawing 1 shows the initial situation.  The cleat screws have 
pulled out of the fiberglass, leaving two ragged holes.

Drawing 2 shows the preparation for the fix.  An oblong hole 
has been cut in the fiberglass and the edges have been 
beveled to improve adherence of a epoxy-fiberglass patch to 
be applied later.  The edge of the hole is at least 1/2" and 
optimally 1" away from the former screw holes.

Drawing 3 shows the marine plywood reinforcing block being 
inserted thru the hole into the blind space.  Note that there 
is a hole in the middle and a piece of small stuff is used to 
control it.  The string will be used later to hold the block 
in place while sealant sets up.

Drawing 4 shows the block being adhered in place, held up by 
the string.  Any adhesive could be used, but I prefer 3M 5200.

Drawing 5 shows the epoxy-and-fiber filler in place, ready to 
be sanded down and finish-coated (gel-coat, paint or epoxy).

Drawing 6 shows the finished repair with the cleat in place.
