Okay.
Building trivia question. This just recently struck me a few weeks ago when visiting a fellow -7 builder. There tends to be two trains of thought when it come to proper counter sinking. Some feel that you need to counter sink deep enough to account for full insertion of skin dimples, depth varying with different skin thicknesses... And others believe that you should only counter sink deep enough for a rivet head to sit flush regardless of skin thickness. Who is following proper procedure? ;-)
