RE: Insight build...another wood roach.
I got a chance to work on the fuse some more tonight: I added the 1/16" vertical grain balsa doubler to the inside of the fuse sides in the stab area. I then made the cutout for the stab using the plans. The stab will be glued in place later at -.5° incidence. Many prefer an adjustable stab, so I included a fore and aft reference hole position on the fuse side view for a stab tube and forward adjuster.
Before moving on, I needed to make a cutout in the fuse sides for the landing gear legs. The approximate cutout position is on the plans. I then carefully squared up and located the fuse sides over the plans and tack glued the main fuse formers in place. I then verified (double, triple, etc. checked) that the fuse sides are parallel and straight and that the front edge of the 1//16" ply fuse doublers begin over the plan as shown. The front edge of the fuse doublers must be even and square to serve as a good reference for setting the firewall and keeping the front end of the fusebox even. I glued the gear plate and support former in place with 1/16" spacers underneath to allow a slight gap between the bottom of the blind nuts and the pipe tunnel floor. The landing gear legs will slide through the fuseside cutouts and be bolted to the top of the gearplate from inside the fuse.
The top view of the fuse shows the firewall at 2.5° of right thrust. The side view shows 1° of downthrust. The downthrust equals about 1/16" of offset toward the back of the fuse when measured at the bottom of the firewall. The right thrust is shown in the top view, so I"ll just glue it over the top view of the plans...tomorrow.
Good night and happy Easter.
