Yes my model building experience is a great asset! The jets fly in excess of 200 mph. Although my bum isn't in the cockpit it is a large investment  any imperfections or slop in the building results in loss of aircraft!
I am a member of EAA 106. I plan on bringing all my stuff to a meeting next month to have the "experts" review my work!

Ok here it is! The last rib coming off the jig!!!!!   Notice the heater/fan at end of jig. Speeds up the gluing process, the build area averages 50-58 degrees!

Making brackets for the ailerons. Once the blanks were cut. Made a jig. It was difficult to keep the larger hole centered. Even with the jig. But I am pleased with the results!

oh btw I am down 12 pounds. The holidays made it tough. But the max kept me motivated! At 50 pounds I begin my flight training! I want my light sport license! Here are some more pictures of hardware. I purchased a metal bandsaw at my local friendly Harbor Freight! After all discounts it was only 188 dollars! What a bargain !!!

Now working on root, tip and number 5 rib. I found making a blank then using plastic wrap I clamped them to the areas where the 1/4 inch plywood reinforcements go. That kept the epoxy from flowing out during the cure time. After they were placed I scraped off excess epoxy with playing cards!

Working on the ceiling must be helping you shed some weight I guessing? Looks like you're making good progress on both fronts (weight and airplane).

Yea, we're just funnin with ya. There's a couple of posts (mostly the rib building pics) that have the pics posted upside down, hence the "working on the ceiling" jokes.

Now working on the root/ tip/ and number 5 rib! Being very careful to make two sets. One set for left wing. Another for the right. All those half empty paint cans we seem to have lying around make great weights when gluing on end covers

Question. Do you think I should prime and paint aileron hinge straps to help prevent rust?

Ok all six ribs have aileron hinges attached! I spent a long time studying the plans here. It really is simple! Extreme caution here.... You to make sure you make one set for left wing. Another set for right! Also my 8 foot bench has been extended to 12 feet! Now leveled and warp free. Tomorrow I start wing spars!

can't tell from the pictures, but do you have "blind" nuts on the back side of the aileron hinge straps?

Yes I do, I backed them up with stainless steel washers! Thanks for the heads up! Great to have experienced eyes out there!
Started the main spar! Cut out the pieces for both. I have one framed up and glued!

Ok. First front spar now has plywood glued on. Second front spar has been glued up. My emergency water supply does double duty as weights! Lost 3 more pounds! 17 pounds total. Any good hints on removing excess glue on the bottom side?

How do you weigh yourself in your anti-gravity work shop?  Must be like working on the International Space Station!

Looking at your hinge straps you just made me think about mine.  I have a old narrow body max and mine are  aluminum made of the same material as the wing strut mounting straps.  Was that a change?  I didn't build my plane.  I looked at mine again and they have a steel bushing in them too.

In the photo of your blind nuts looks like your bolts are a little short, remember 1-3 threads sticking out.Good job on the weight and work!

Thanks for pointing that out! I actually use shorter screws where ever the is a blind nut because I don't want to wear them out with multiple assembly/ disassembly  required during the build. I keep a checklist so I don't forget and leave them there by accident!
That does bring up a question.... 1-3 threads required. It is ok to have more than that showing?

They dont want you to go over 3 threads because you dont know if you are compressing wood or just running out of threads.If more than 3or4 i foget then you need a shorter bolt. I did not build my plane, but not wanting to were out your blind nuts makes good cents, but dont forget them. Do they make a castle blind nut you could wire tie and forget about ?

Actually, I don't think you'll be removing the ailerons, unless you're doing work to the airplane there.

For transport, my ailerons are not removed from the wings, just the wings removed from the fuse and control cables, disconnected from the wings....

anybody got a video of wing removal?

Mainly for the build. I figure the ailerons need to come off and on a few times to get everything correct
