I have been looking but cant seem to find the thickness break between dimpling and countersinking for rivets. The plane I am building is mostly .025 and .032 skins which i assume will require dimpleing. my main question is the spars are .050 so would i dimple or countertsink for the dimpled skins??

the plans say nothing about countersunk rivets as they call out for USM pop style rivets or to use solid rivets (ms20470ad4-4 or 4-5) where ever possible.I really like the look of countersunk even though they are more work to install

There are some places that will require blind rivets although I am having trouble finding the USM rivet (AD42 and AD43) or an equivelant countersunk blind rivet. I considered Avex Rivets bit I am unsure about the strength of them versus the USM

by the way the plane is a late 70's design Durand MK V all metal biplane
