Ok, so let's get rolling, first start with the firewall parts. I chose to use an 1/8" dowel to key them together, helps in the alignment department. Line all the parts up, and bore the 2 holes on the outter marks for centerline of the engine's crank, Then test fit and prep for epoxy lamination. I used a piece of scrap MDF and put some monocote clear backing on it to help keep the firewall from sticking. Just epoxy the inner surfaces and slip each one over the pegs and clamp it down, wipe off the excess and let it sit for about an hour. In the meantime, setup the fuse sides, this is where one of the 2 mods comes into play, I chose to do doubler reinforcement along with a strip of carbon-fiber and kevlar. You only need to do one of them, either glas it, wood, or carbonfiber/kevlar, I did two of them, and yes, you will have to modify the former. But this is really not that big a deal to do, takes more time to line it up with epoxy and weight it down than to make the reinforcement to the sides. So I used MAS epoxy and medium hardener, so this is the extent for the night, tomorrow, it will get framed up and start looking more like a fuslage than a bunch of planks. In one of the pic's, I show a easy way to ensure alignment, just make sure a scrap piece of liteply is flush along the former notch in the front of the wing notch. This will allow you to have the doublers in the same depth and location on bolth sides. Hope these pic's helped.
