My question concerns a heavy folding garden table made of some heavy hard wood - teak I think. It was damaged in a storm last Autumn. Today I got round to looking at the damage. Part of the folding leg structure has collapsed. None of the hardwoods seem to be damaged. They were joined by what I thought were mortice and tenon joints but it seems the tenons are actually all dowels about 4cm x 1cm cross section. I can't see any sign of glue having been used but there seem to be (rusty) panel pins through the base of some of he dowels diagonally into the inside of the mortice in the hard wood.
What is my best method of remaking these joints? Incidentally those that are still in place are rather loose.
TIA Frank
