Jolly,

Dan's idea of drilling holes into the bracket helps to retain the adhesive and forms an epoxy bond across the bracket between the lite-ply plates on either side of the bracket in the wing. It is still beyond me how a 2m wing is supposed to be supported by a short bracket like this but so be it. Actually the height of the bracket is the key here as that is what supports the load but if the bracket detaches... well, we know the result.

The above will just help insure that the bracket is bonded across the wing rather than in a less reliable plate-to-plate laminating fashion. However, it is still a high stress point to locate the load over that single bracket even if it spread out by the bond to the adjoining ply in the wing panels. As mentioned, I would still glass the section under the fuse. If it's glassed, you could probably just insert the bracket without glue and there is no way those panels will come apart (using the right glass) - not that I would ever do that...

David.
