Default RE: Build thread for a Carl Goldberg Eagle II Trainer??

I went with glueing up the fuse with it all together using rubber bands to hold it in place and then used clamps. With the ass'y on the top view and lined up. I ran small dabs of glue on the front side of the former sides and fuse and let that dry (all but firewall). The aligment was then bascially locked in place. The pic now shows the fuse angled slightly toward the front of the bench with painters tape running along the bottom corner front to back with clamps every few inches to keep it tight. The fuse is angled sligly so the bottom corner is the low spot front to back. I put some expoxy along that joint and hit it wth the heat gun a few seconds which turns it into a thin type syrup. This allows the epoxy to seep fully into the joint and the wood while the tape keeps it in place. This part was my dilema as I wasn't comfortable with not having glue on the contct surfaces themselves but heating the expoxy solves that issue. I also do this with the heat gun when fuelproofing the tank area as it again seeps ito all the nooks and crannies and is easier to paint on the wood w/out using thinner.

When this is dry it will be safe to move more easily without affecting alignment and will I will then:

1) Do the other bottom side (angling fuse to other side)
2) Do the front of the formers (bottom and sides - fuse point up resting on tail very slightly forward and angled to one side, then the other)
3) Do the top of the fuse (fuse turned over and each side angled once one side is dry)
4) Do the top of the formers (fuse bottom is up and nose slightly up.
5) Do the backside of the formers. (nose pointing down)

By doing it in steps I can angle the body as needed so the expoxy stays put and does not run or drip where its not needed. This is just how I do it for sheet type fuselages and there are many diff ways. I'll post pics of each. Stringer type fuses are another can of worms.

Once the formers are done, I'll go about adding the bits and pieces like the wing saddle doublers, hatch supports,, etc. then onto the firewall and figuring out the side mount of the motor. ( I need to reset that clock!)
