Spent the day riveting the top skins to the tailcone. We also deburred the top skins of the baggage area then started riveting them to the fuselage. We also put structural epoxy into the 3 missed drilled holes and filled the remaining slight depressions with filler. We did not have enough stringer/stiffener raw stock to add the required 2 additional ones. Ordered more from Rans and noted with tape on the top. we Will finish next time.
