This is a very old method to build fuselage, but just in case!!
The Pod & boom fuse have a big problem:
Is the boom it self, very flexible or very spensive if you choose carbon fiber, (also a very dificult to buy).
The modern gliders have a very thin fuselage, and also light, and roled plywoond becames to be a very good choice.
Difficult to build you may think at this momment.
No !!
In fact very easy to buid and conform.
In my new model a Frigate whit carbon Fiber Spars, after make many drawings, I realise that a roled plywood could be a easy method to obtain a good fuse , clean and strond.
Step 1, Cut the plywoow sheet, I choose a 40mm diameter in the nose, and 65mm hight in the main cavern (that one on the leading edge of wing), 55mm on the trailing edge cavern, always whit 40mm in basic diameter.
The longerons is in hard plywood from midwest as the plywoog sheet for be molded.
Caverns also in hard 3/16" plywood.
Step 2 , Whit all the longerons glued in position, put the fuse sheet in watter, and whait untill, the ply wood get's very flexible, pre form the total fuse.
Step 3, Whit the help on many rubber bands form the final shape of the fuse, glue whit thin CA, and whait untill dry totally.
Step 4, Put the nose block and cannopy, I prefer made in balsa .
Step 5, I use a cloth of fiberglass 3/4 oz from Hobbico and Zap finishing resin, after dry a sand peper # 320 to the final , aply and lac or paint.
Any doub about just call me!
