now the tanks have been drilled and prepped we moved onto riveting the ribs and stiffeners in place. there is as much prep to get the tank ready as there is to do the riveting. all surfaces where the proseal touches must be CLEAN so that is where most time is spent.
here we are partially through back-riveting the stiffeners on.
we managed to get the stiffeners done then moved onto the ribs.. doing 2 ribs on the first session then doing 3 on the next one.
method to mix proseal for the tanks
applying proseal to the ribs before inserting them into the tank skin, then each cleaned rivet is put in place and riveted.
