Good Evening Sparky's Gang.......
My question here is simply.......Does anyone have a slick, cool - errr, easy way of jigging up D tube wings?
I'm working on my Akromaster and doing it how I did it in my attic in '70, but there must be easier ways!

Jim,
I'll give you a method that is slick, cool, and an easy way to build a D tube wing, if you promise one thing....that you will post lots of construction photos for us to admire !!
The Morris system is, of course, a very well accepted way of doing it, but here's a system that I like, with jig blocks you can easily make. A table saw is nice, but you can also get accurate jig blocks if carefully cut on a bandsaw. In any case, you must clamp the clamps together, and disk sand to make them identical in heigth. Then the blocks are lightly CAed to a flat glass surface.
This photo depicts a Fancher "Imitation" wing in progress. Someone is bound to spot the tab on the bottom of the near rib, and question why I didn't use the tabs. The simple answer is, that the tabs don't help any when the wing is flipped over to do the opposite side.
Note that the LE blocks are individual, the TE block is one piece. That was just an experiment, and the one piece jig did not offer any advantage, and did have a couple of draw backs. I prefer the individual blocks.
I happen to use stock 1" x 2" pine, as it was dimensionally consistant, and readily available. Other materials are fine, including hard balsa.
I also made this type of jig block that corresponds to a square leading edge that is rotated 45 degrees horizonally, like a Twister LE.
Even if you don't use this type of jig block system, we still want to see the construction photos !!
Cheers.
