Spars

YES back on the wings ๐Ÿ™‚

 

After building all the ribs a few months ago, I now started working on the spars, that together with the compression struts form the skeleton for the wings.ย What I am doing now (see below) is drilling the 4 holes in each spar, where the compression struts are mounted. In order for all the holes to be in the same direction, I clamped the spar in the middle and basically move the electric drill press around.

At the end of the spar is a small extension that slides into the spar that I squashed, by heating it up a little and using the hammer to deform it. This is done now so I don’t have to do it later when its assembled. The tips are narrower as a 3/4″ tube is riveted in there, joining the leading edge of the wing to the trailing edge of the wing. You can just see one of them on the right side of the photo.

The wing shape I am aiming for is shown in the drawing below. It is part of a drawing of the Bleriot that did the original Channel Crossing in 1909. This wing is a wing warping one. My one will have ailerons.

Very nice shape I think ๐Ÿ™‚
