Tee Nuts

I had the upholstery re-skinned over the winter. I removed the pieces from the boat myself and delivered them to the upholsterer. The piano hinge at the top of the observer’s seat was anchored by a screw into a tee nut attached to the backside/ inside of the seat frame. The tee nuts had loosened up over time. Rather than fix or replace them, the upholsterer removed them and suggested wood screws. To me, this is not optimal since they have greater chance of loosening up in this type of use. I now can’t get access to the inside/backside of the seat frame, so tee nuts are not an option. Any suggestion as to what I could use that would be the equivalent of the tee nuts?   

Take a large hole saw & cut a plug around where the Tee nut went. Make a mating plug to refit, putting the tee nut in that. You might want to epoxy in a couple of thin wood 'slats', off-center of the hole (a door frame shim would work) to give a back stop. Then epoxy the plug back in. It would have been much easier to replace the wood when the skin was off!

Yeh Alan sounds like he has a 97 no wood.

Jim not quite sure what the problem you are describing is do you have a picture of it?

But the interesting info in the diary entry was that he actually sold JoeinNY the future worlds fastest SN2001.

Jim - Sorry for my left-field answer. I can see how the tangs of a tee nut wouldn't dig into fiberglass. Poor design from the factory in the 1st place.

"Tee Nuts" would be a good stage name for a rap star
