On my 0.060 stainless floor I've been using the standard universal head CherryMax (CR3213) rivets to hold the bellypan in place while the structural adhesive bonds. This has worked mostly fine but in improving the ride control on the car (and thus a lower ride height) the nominal kerb excursion wipes these off pretty swiftly and creates more maintenance and/or accelerates the delamination of the bond.
I have previously avoided the CR3212 (MS20426) flush rivets as the c-sink depth of 0.041" on a 0.060" sheet seems to be a bit thin. But wondering if anyone has had any luck with the CR3214 (NAS1097) flush rivets which are labeled as 'thin top sheet flush shear head' and have only a 0.028" c-sink depth.
Details here, page 9 - 10: http://www.cherryaerospace.com/files...og/CA-1011.pdf
I'm still trying to decide on what the thickness of my next floor will be (though I did just sign up for a half marathon...) and interested in the best option if it stays at the 0.060" thickness. Both parts appear to be readily available, if not cheap...
Advice?
