Hi All, just thought I'd pass along this handy DIY dihedral jig idea so you can fabricate one of your own
for glider builds. It's a fast easy project that shouldn't take you much more than a half hour and only
requires a ruler and hobby knife.

It's not my design, Brad from the Nighthawk Gliders channel on youtube made one for himself for his
balsa chuck glider builds. I built mine from 1/4" balsa sticks glued together but you can use whatever
you have handy.

I just followed his dimensions: 3" tall in the center, and on one side the lowest step is 1/2" tall, and
each step goes up in 1/4" increments. On the other side the 1st step is 3/8" and each additional step
increases by 1/4". That gives a nice range from 1/2" to 3". So much easier than trying to find stuff to
stack to get the dihedral angle correct when sanding or gluing wing roots.

Below is a pic of all the dimensions to make it even easier to get started. After I finished mine I
realized that I could have glued one side on at a right angle so that the jig is self standing. You might
want to do that as well or change the step increments to suit your needs. Happy flying!
