Chapter 19 - Wings - Part 16

More work today on the left aileron and wing.

Pictured here I have clamped a straight edge on the wing to guide me while cutting out the hinge notches on the top skin of the wing. This ensured that the hinges were all in line with each other and inset the proper amount.

Pictured below is the inboard most hinge with clickbonds test fitted. The plans call for a machine screw and a nutplate to be riveted to the hinge. The ckickbond fasteners are simpler to install and will have a seamless appearance then the wing if finished. This hinge happens to be 8" with three fasteners, the middle and outboard are 6" with two.  

Pictured here is the middle span hinge with showing the clickbond fasteners protruding through the top skin and hinge.

And here is the inboard hinge clickbonds floxed in place with two plies BID. The hinge has a protective clear tape to ensure that any flox or epoxy will not bond the hinge to the clickbond or wing.

Work continued on the left aileron today. I completed fabrication of the A-2 and A-5 brackets.

Next I resessed the forward face of the aileron to mount the brackets flush with the foam surface. These were then bonded in place with micro along with the 9"x3/4" A-10 torque tube.

Monday I was greeted at my front door by a box from the Cozy Girrrls containing many pieces of wing hardware.

Also earlier, last week, I received the wing root spherical bearings from Infinity Aerospace (the blue bearings in the photo).

And as luck would have it, another builder was selling extra universal joints and I managed to pick them up for a little under Aircraft Spruces price.

This weekend I will attempt to complete the left aileron and begin work on the right.

Chapter 19 - Wings - Part 13

A couple of weeks ago I began working on the left aileron. I started by carefully ripping down a scrap of lumber to create a 120 degree guide for the Fein tool while cutting the aileron from the tip wing skin.

Pictured here is the top wing skin after cutting. This part of the operation was done correctly. Unfortunately cutting the aileron from the bottom skin didn't go as well. I made a stupid mistake when transferring the measurements from the plans to the wing and then cut too much from the wing. I was really upset with myself for doing that, but after some calm planning I realized that the fix was not going to be a big deal at all. I glassed the aileron back onto the wing (underside only), let it cure and re-cut the aileron correctly, all was good in the universe again. Unfortunately I did not take the time to take photos of this process.

Pictured here is the left aileron with the 7/16" steel rod counter weight bonded in place.

Pictured here is the aft wing rib that is laid up with 3 plies BID glass into the area the aileron was removed.

Aileron control hardware should be arriving by UPS tomorrow. I hope to have this chapter wrapped up by then end of this month or early March.
