I was looking at using the Click-Bond nut-plates for my RV14 wing tips, but at $4-5/each, I am thinking not. I started looking around for alternatives to click-bond, and came across a company called Rotaloc that manufactures "bonding fasteners". They come in all sorts of sized, materials and finishes. They are meant to be adhesive bonded to a substrate. They look to be popular in lots of fields, and applications including composites. They do support a screw size of 6-32, but it is not a stock item, which means a custom order is needed, and that involves minimus of 1,000 parts and 5 month lead times.
The Up side to all this is the price, they are less then $1/each if ordering from stock. Down side, they only stock some options with the smallest nut size being 8-32. That is why I ask, are 8-32 to big for attaching the wing tips?
I have not started my wings yet, so I have the time to put in a custom order, but I don't need 1000 plates. I suppose, if a group were interested, we could pool together an order.
Now I am not a chemist or structural engineer, I know there are those that would advise not affixing the fasteners (plates with nuts welded to them) with adhesive, but I love the idea of not riveting these in place.
Thoughts?
