Today I finished riveting the seat and baggage ribs. In the process of riveting in these tight areas, I found that my rivet gun was spraying lubricant out the exhaust. Maybe I am oiling it to often, so I will cut down to a drop every other day of significant use.
After getting all the ribs riveted in, I replaced the forward portion of the F-606 and riveted it the the longerons and stiffeners.
