Lyle and his friends Paul and Greg Klema arrived at 9:30 and we started riveting the 601PP skins onto the skeleton. Lyle did a great job of teaching me the techniques involved in countersinking, rievting and bucking. The work went fast and after about 4 hours of work the skin was riveted to the front and back spars and all ribs #HS-706 and HS-708. Then Lyle gave me a demonstartion on squeezing the edge rivets and the left. I then proceded to countersing and rivet the edge of 601PP. I worked for 3 hours and quit for the day.
