Step 5 - Firewall

I made another mistake on this part in cutting out the longeron holes on the permanent fire-wall. I hope that this doesn't bite me later. I am confident that I can adjust but I'd rather have it right the first time. I'll let you know when I get there.

Both the permanent and temporary firewall are kinda fun though. Big sweeping continuous curves make for fun cutting and finishing. I probably should have mentioned this earlier, but you should definately buy a roto-zip tool with a router handle for this job. If you use this combo with a laminate bit to trim your pieces you will always have perfect trims.

There is one moderatly nerve-racking part here in having to install the engine mount hardpoints. The only thing that goes through your mind is, "Man i hope I measured everything PERFECT on this sucker" They are only 1" x 1" . You also have to insall 16 blind screws here. I have read about people saying that the heads break free and cause the screws to turn in doing it the plans method but I did it that way anyway. I floxed them in there pretty well and I trust Nat (not me the designer of the plane).

WOOHOOOO All done and on to chapter 5
