So. An experienced builder would just go ahead and build it.

However, for me there are some worrying differences between the cut out parts and the plans. Formers 3, 4 and 5 of the fuselage are 2 mm narrower than the plan, so I took a punt and set them up 1 mm inside the lines each side.

Then I assembled them over the plan and attached the look alike wing roots on to their tabs.

Because there are so many competing angles, I'm going to build the spars and ribs 1 on to this framework. This should allow me to get the Graupner box level and set up the dihedral and the forward sweep.

Then I can remove the spars and build the rest of each wing on the board.

Well, that's the plan - anyway. :geek:

OK. Here is the Graupner tube set up in the fuse section . . .

. . . and so, on to the spar.

I've calculated the forward sweep to be 87º so I'm cutting some guides for setting up the spar to Rib 1.

We're in a week of Lock Down here, so plenty of time to take my time. ;)

To help me get my head around the construction, I have installed the Graupner box in a short section of the fuse and now I'm joining each spar to the "root rib" which is attached to the fuselage.

I've cut the steel bar to length and JB welded a stopper pin into the end of each of the brass tubes which go into the wings.

Now I'm offering up the spar to the fuselage and epoxying the brass tubes into each side.

I've begun to clad the brass tubes with 3 mm spruce, by coating it on the top and pulling it up against the brass tube with copper wire.

Once the high strength epoxy has set up overnight, I'll continue boxing in the brass tubes.

Then I should be able to remove each spar and build each wing around them.
