Exhaust tunnel progress and first aileron out of the jig.
Lot's of work got done today. This morning I pulled the aileron out of the jig. It looks good and stayed straight. The trailing edge has a very slight rise in the middle, but that should be correctable when I install the TE plywood. More pictures here.
I got out to the hangar this afternoon and started hacking on sheet metal for the exhaust tunnel. I came up with a plan that had few critical bends on any one part. The width of the middle tunnel piece had to have the right angle and be pretty close to right width. I left some length on the part so that it could be slid forward or backward as needed to tighten up the fit with the two side pieces.
This all worked out much better than I had hoped. I was expecting the first parts to be 'practice' parts, but they are looking good enough to keep. There is more work to do trimming and fitting some of the edges. I also need to get the hardware installed. I got most of the hardware done for the two side parts, but the tunnel is only mounted with a couple clamps right now. More pictures here.
