I thought I would add some pictures of the construction up to this point.
I started off with 3/8x3/8 spruce for the longerons. I soaked these in the bath tub with ammonia. These were formed over the plans, yes those are nails in my building board, with spruce this size pins don't cut it. The uprights between the longerons were made buy adding 3/16 square stock to 3/16x3/8 stock. The uprights on the original were "T" shaped and tapered top to bottom. I tried to do something resembling this as eye candy when the sun shines through the covering. I pinned the uprights and cross pieces with bamboo skewer stock. I stained the frame because...well WWI warbirds always seem to have the frame stained. I've also managed to add the rear tail skid supports.
Art,
I don't see this plane weighting more than 20-25 lbs. I'd sure like to use the B&S 35 cc four stroke if for nothing more than the sound. Also feel free to post pictures of your N-11 here I'd sure like to see what you've done and steal your ideas and methods
