| Take a close look at the picture above. Notice that the horizontal
spar is sitting on a block of wood. Behind the spar is a vertical,
darker, piece of wood. This is the leveling block. During
construction of the wing, you will use four leveling blocks mounted
on the four corners of the wing. You must make your own leveling
blocks or maybe someone sells them, but I haven't heard about any for sale
through any store.
Not shown in this picture are the clamps and pieces of wood used
to isolate the clamp from damaging your spars. Once your
ribs are placed on the wing spars, you must be sure that they are
absolutely straight, that's why we use these leveling blocks.
Once the wings are assembled, but not glued, you will place a level on
the spars and clamp them to the vertical parts of the leveling blocks.
This will provide proper alignment for the gluing process. |
