- #1 shows the dimple after being flattened with a hammer, G clamp and rivet squeeze. - #2 shows the same piece from below. - #3 shows the lack of closure using a 0.025" packer. I think the packer would have to be at least 0.050" to expect a tight fit.
Iv'e tried: - trimming off the dimple from the under side of the skin. This works well with either the Dremel with a flap wheel or the die grinder with a soft pad and leaves a fairly smooth finish. This opens the hole in the skin so that a 5/32" rivet fits fine. I then drilled out the the piece underneath and set a 5/32" dome rivet. - fitting a packer, .025", between the upper and lower pieces. I tried the counter-sinker (didn't work as usually resulted in and egg shaped hole). Also tried drilling a 5/32" hole in the packer to accommodate the dimple. I had no luck with using the packer (shim) as .0125" is too thin and I couldn't get the pieces tight together. I could possibly get some thicker material at Serpentine, but I think the result would be inferior. - flattening out the dimples using a hammer, a G clamp and the rivet squeezer. The squeezer gave the best result. (photo 162 shows top side, 163 shows bottom side)
I think the best fix is to flatten out the dimples with the squeezer and using a standard 1/8" rivet. The head of a standard rivet covers the distortion, and the result looks like a normal dome rivet. Bearing in mind this may have weakened the skin somewhat around the hole may justify the 5/32" rivet. I could either trim off the dimple with the Dremel or flatten it with the squeezer and re-drill to 5/32".
