Jig for sanding BubbleDancer LE and TE

[atjurhs]

Hey guys,

I've got my panels constructed but before I start joining them together I wand to be done with as much of the sanding as possible. The charlesriverrc website has the file "wing_plan_V2.pdf" that state the angles at which the various sections should be. Has anyone built a jig that will guide a sanding block along these angles? I'd like to get the airfoil as close as I can (and I know there's only so much that a built-up balsa wing construction method can do). So, has anyone built a jig to do this?

Thanks!

Have you seen this article on the CRRC website?

The latest RC Soaring Digest has one in it, i'm about to build one for my Sagitta.

Brian, that's what I was wondering if anyone had actually done and it appears that Lothar Thole has in the RCSD article. Thanks Miraj.

Any other realizations of a sanding jig?

Just two pieces of two inch wide 3/16 inch thick flat iron bolted together offset by one inch for makng 1 inch wide 3/16 trailing edges for a 10 inch chord AG35 airfol. I have used the same jig for SD7037 airfoils.
