Flattening the wing + CF reinforcement

[afcub]

Dillzio,

Did you find you had to cut different depths? Meaning, did you cut shallower in the middle of the wing and gradually increase the depth of your cut as you move from the middle towards the wing tips? (make sense?)

I read somewhere the wings were thicker towards the ends than they are in the middle so your cut would vary in thickness to lay your wing flat and remove the dihedral.

If you make the wing flat you don't need to cut different depths. Its only if you leave some dihedral in that you need the cuts to be deeper closer to the wing tips.

Getting the cut depths right is a bit of trial and error anyway, you cut a groove in it, put in the spar, and if it's not quite deep enough you cut it a bit deeper. It doesn't have to be perfect first cut. In fact, I recommend just scoring the surface a few mm deep using a ruler as a guide, then make the cut deeper by free hand
