Sven,

As much as I like to take credit for the "countersink" method I learned it from a guy I knew at Hinckley back in the 80's. Morris Yachts also uses this method..

Here's an M-36 being countersunk for Dorades..

When I installed my stanchions, I cut 2"x3/4"x1/4" stainless bar and welded the 14/20 nut on the plate and then over-sized the entry side hole and re-tapped the nut. During installation, it was a real mess. I would coat the nut plate with 5200 and then have my helper install the bolt. Most of the nut plates had to be put in place by feel. In the end, it was well worth the effort. I have removed and replaced several bolts and the nut plates stayed in place so that I could reinstall the bolt by myself from the exterior
