This has been a big hurdle to the get the engine beds complete and ready for metal. They are a composite of 4 layers of 3/4" Coosa and 1 layer of 1/2" Coosa laminated together with epoxy and a layer of 1708 between each layer. They are bedded in epoxy putty and tabbed. Notice the 1 1/2" 45 degree chamfer strips on the outboard sides of the stringers. They are also bedded in epoxy putty and tabbed. I think they will hold the 380 hp Cummins that will be riding atop of them.
Lot of work and epoxy are in these stringers

Its going to be another 3 or 4 weeks before we install the motors. I want to get the bulk of the fiberglass in the cockpit area completed before install the engines.
