I am in the process of installing the seat back frames and I am a little puzzled. I have tried dry fitting the frames in a couple locations and they look like they stick up too high where ever I put them. Is the thought around the process to get them installed and then you will use a plane/grinder/sander to level out the top of the frames and stringers to have a flat surface to install the seatback top?
Also in the manual it states that you are to put a fillet on the outside and inside of the rear cabin wall? The outside makes sense, but the inside doesn't.
Should the rear cabin wall be setback about 1/2 inch from the edge of the decking to allow room to apply a fillet? This will leave a little lip on the inside and I don't recall seeing this on any of the blogs. However, this sort of makes sense to push the rear cabin wall back some since the seatback boards are almost too short.
thanks
