What not to rivet together

For some part assemblies, you can't install rivets in every hole at the same time. Some have to be left open to be installed with a different part later on. That was the case during this stage of the fuselage build. To prevent installing rivets in certain holes, we took a handful of clecos and wrapped some black tape around them. Then simply use these special clecos in place of the non-marked clecos and you'll stop having to drill out perfectly good rivets!
