Here is the second side before the inner layer of 26gm glass. High vacuum forces the rohacel to fully conform to the mold.
Excess resin is forced through the perforations into the peel ply. Before inserting the rohacel into the mold I deresined the glass with a couple of applications of paper towels.

OK so I want some stiffeners down the center of the fuselage.. My plan is to glue in these 30mm wide strips of 2.75mm rohacel reinforced with carbon tissue (2 layers on each side). Here they are,30gms.

Got the fuselage joined, too busy and sticky to get shots.
Cut strips for joining. The glass is 2 layers of 80gm laminated with spay glue 45/90 orientation. This stops fraying and stretching.

The seams worked out cleanly. I put in a bead of epoxy/micro balloons on each edge first. The glass strip was pre-wetted and de-resined before attaching. I used the lap joint method for assembly.

Not sure where the wing tube will go. That will depend on the balance. The rear end used 75gm glass instead of my original plan to use 50gm. It is much more ding resistant and not a big weight penalty. The entire fuselage is cored with 1.5mm rohacel, it is very stiff.

I usually start by setting up the stabs. I set up this false tail post with access hole to hold the fuselage in position. I need to get the tail surface honey combed so Ewan can have his foam cutting guides back.

Well it is done but I think my usual system is probably just as light and a lot easier.
Ready for the balsa skin. 3K carbon tow stiffeners.
