Yes. It worked quite well, but it covered only a very small gap. The more flexible the dried glue is, the floppier the joint would be.

Bamboo is a very hard wood and would be difficult and time consuming to make that many scarf joints. It was much simpler to sand the ends square and butt-glue the new piece in place, then add the supports later. Those little pieces of cardboard added a miniscule amount of weight. Stripping the bamboo wasn't too difficult. I used a sharpened Craft razor blade and stripped by eye and feel. Some skewers wouldn't strip evenly and were tossed, but others were good. There was a lot of scrap, but the skewers were cheap.

Outstanding.  I'd have been tempted to try a scarf cut to join the two pieces of bamboo.  But I don't know how you were able to strip the bamboo so consistently.  I've heard of some folks using 1/32" basswood but it's very hard to strip into stringers because the basswood wants to follow the grain and not cut consistent 1/32"X1/16" stringers. 

Your stringers look great!!! Smiley

It took some time and patience, but the old stringers were removed and replaced with bamboo split from some bamboo skewers. The split bamboo was about .75 to 1.0 mm, roughly square and just over 9" in length. It took about 3 pieces to get from nose to tail. I used small pieces of corrugated cardboard to support the joints. I added a piece of posterboard just behind the canopy for tissue attachment and two pieces on the fuselage just behind the TE to grip when launching so that I don't punch more holes in the tissue. Current weight without props is 114 grams. I think that it will take about 10 grams of additional weight in the nose to balance properly.

Back to the fuselage. I accidently crunched the nose a bit, and decided I had to add a little bit of support with bamboo stringers and a bit of bamboo (circled in green) to strengthen the posterboard supports. I used a piece of 1/64 ply to strengthen the main spar joint. I thought a bit about strengthening the front and rear LE joints and I remembered an engineer in our homebuilt aircraft club who designed his own seaplane. He demonstrated to us a quick way of strengthening joints by using strips of fiberglass cloth soaked in resin rather than ply gussets. So, I used a strip of coffee filter soaked in glue wrapped around the joints. I also added a bit of posterboard at the LE of the wing to attach the tissue to, and some posterboard over the small gaps between the fuselage and the rear part of the wing root ribs.

That is absolutely amazing!  I have a WW2 era P-47 comet kit with the cardboard formers.  I always wanted to build it because it is the first stick and tissue plane I ever attempted.  This build is WAY past that and very nicely done.  Thanks for taking us along for the ride. Smiley

Every now and then, something will come along that words simply won't do justice to. Such is the case here! From its inception to now, this is just an amazing piece of imagination and skill. A beautiful piece of work!

Lots of non-airplane stuff has kept me away from building. I glued the tail feathers and the wing in place. The wing needs a shear web over both sides of the main spar, as well as the LE & TE. I used a black felt for the cockpit and a thin piece of acetate for the windscreen. I broke fuselage stringers putting things together and I punched a few small holes in the wing. I am considering replacing the fuselage stringers with bamboo. I didn't cover the fuselage first because I figured that I would just be punching too many holes in the tissue. It weighs just over 100 grams as you see it.

Thanks. It is learn as you go along for me. After a lot of contemplation, I figured on the rear motor peg. I made a 'plank' (first pic) out of two bamboo coffee sticks glued side-by-each and faced one side with a piece of 1/64th plywood. I then cut out 'upright' pieces, drilled them for the motor peg (bamboo skewer) and shaped them. They were glued to the sides of a 1/2" piece of plank. When dry, they were glued to the wing TE. I then made 'struts' out of some bamboo toothpicks to strengthen the motor mount. Each mount weighs about 0.6 g.
