To start with we took on a number of misc tasks including riveting the rear arm rests to the bulk head, some of the rivets near the floors that I could get with a squezer or solo. We then set to work ont eh F-850 skin. I started by clecoing it in place, mixing up some proseal, putting a big glob in between the skins per the instructions. We then set about to riveting. I tried to set the rear most rivet, ended up drilling it our and putting in MK-319BS for the aft two most rivets. the rest were set by hand.
