I have not done much besides research lately. I went to see another BH project the other day which was very worthwhile, as I met some great guys, saw an awesome 4 place build, ready to cover, and saw a ton of great ideas and processes. Most importantly I got re-inspired. With a bit of help from Linda today, I got the ailerons and flaps hung on the second wing. I'm now mounting nutplates on the back of the hinge mounting reinforcements on the aileron and flap spars. I did not do this on the first wing (just used nylon locking nuts. They are stronger, but you would have to fit the fabric around and over, and if you ever needed access to the hinge nuts, you'd have to slit the fabric. These pictures show the nutplates riveted onto the back of the control surface spar, and the resulting flush surface on the front face of the spar, which will be easy to secure the fabric covering to, and then bolt the hinge brackets to after covering. I'll try the nut plates on this wing and then most likely do the same on the other. Unfortunately,this will require working between gusset plates on the control surfaces.
