Scott, Thank you very much, you just made my day. I have been following your work closely and have "stolen" more than a few of your ideas, you are indeed an excellent craftsman.

Hi Ed, I just looked at your website. Your workmanship is outstanding.

Thanks John,
It looks like my site is down and the links don't work. I will fix it when I get home from work.

Thanks Ed...been following your progress and it looks really good.

John,
I didn't exactly follow the plans when it came to the tail piece but I am very happy the way it came out and it is very strong.
I routed 1/8 inch slots for gussets and a 1/4 inch slot at rib #6 for the aileron brace.

I also cut slots with a dado into the tail piece for the ribs to fit into. I glued it using pieces of 1/4 plywood clamped to the bottom side of the ribs to keep it all straight.

When it came time to install the aileron brace it fit perfectly into the 1/4 inch slot that I had made earlier.

If you follow this link I think you can see it pretty good.

It appears all 4 ribs get a large 3/32" piece on the inboard section aft of the rear spar. The top wings are similar on the outboard side except for a space for the aileron spar (or do you butt that spar against the 3/32" stiffener). It seems the bottom wings get the stiffener from the aileron spar and beyond (outboard section), so you'd still have gussets #2 and #3 at the spar location (on the outboard section).

I'm stuck though...

I have not figured out how to attach the trailing edge piece to rib #6. So, I think I'll leave these pieces off for now. I can shape them and glue them onto the rib once the rib is on the spar and I have the trailing edge piece made.

I built mine with gussets on one side and then sanded them off when I realized my mistake.

I did not apply any of the regular gussets on the trailing area of rib 6 (aft of the rear spar). I installed the 3/32 doubler on the inboard side and am holding off on the outboard side until I get around to assembling the wings (hopefully this year). If you look closely you'll see that the outboard 3/32 doubler needs to incorporate the trailing edge which you can't do until you build the wing.

The plans clearly state to not apply three gussets on the outboard section (trailing area) of the aileron bay rib; #6. What about the other side?
