Thanks Matt. Are u saying the walls will seperate from the floor, not sure what u mean. The floors glued to 3 of the fuse formers with the top of the sides glued to 1/2" foam and then glassed with 2oz cloth.
Worked on the front end today
Got the spinner ring set, added air intake, located needles, and reinforced the firewall with g10.
No....what I meant was the bottom of the fuse where the tunnel sides end should be lined with strips of hard stuff. It forms rails along the pipe tunnel opening if you will. Over time, if not protected, it will dent and ding and tend to look shabby. I have used ply strips and carbon rod. I like the carbon rod (.078") fared in with epoxy filler.
The tunnel itself is fine. I made mine from 1/16" balsa in past builds. The tunnel sees no forces per se. The pipe should be soft mounted to fuse former.
