Finished working on stiffners. Match drilled all stiffners and E-615 & E-616PP. Dimpled all stiffners and left and right elevator skins. Prepared rivets for next work session. The rivet tape works well. The orange portion of the rivet tape is non-sticky. You just place rivets in all the holes and place the tape on the line of rivets. Then you turn the skin over and lay it on the back rivet plate! Then using a back rivet set you go down the line and buck the rivets. It is an easy and enjoyable way to rivet and does a GREAT JOB!!!
