Meanwhile, the stab is built from 3/8" square balsa. The LE was not glued on, but it pinned firmly into place to keep everything together. After the glue dried, all the corners were drilled out to accept 1/8" dia birch dowels for pinning them together. I prefer pinning then this way, much as furniture is done, because it seems to be stronger and lighter than gussets. It can't be used everywhere, but at this thickness it's very good.
In this photo you can see the stab positioned beneath where it will be on the fuse. You can also see the nose gear in its well. The battery access is behind the nose wheel, in the 6" space between the DB pushrods. You can also see the 1/32" x 1" ply doubler that runs from the rear spar up to the firewall.
You can also see the cowl in place. It was built from four (top, sides, bottom) of 1/2" balsa sheet with a 1-3/4" nose ring. The motor is installed and a plastic spinner to serve as a sanding guide. This is a good use for plastic spinners - sacrificial sanding templates!
