Started work on the aileron bracket assembliesStarted work on the aileron bracket assemblies
I found all the parts and clecoed each bracket together. I couldnít find the angle piece AA6-125x1x1 which makes the aileron stops. I ordered some 1 inch and 7/8 inch Delrin Rods from Aircraft Spruce to use instead of the aileron stops. You can see a write-up on the Delrin Rod Aileron Stops HERE. Iím sure that the 7/8 inch rods will work, but I ordered a 1 inch also just to cover my butt.

After countersinking the holes directly behind the bearing and priming the parts, I clecoed everything together.

I used my small no-hole yoke on my pneumatic squeezer to rivet everything together. I put the manufactured head of the rivet on the opposite side of the angle piece when riveting the angle on. This made positioning the rivet squeezer much easier.

Started riveting the inboard aileron brackets together As you can see here, I've already finished one (practice piece, don't cha' know). I started by clecoing one of the main longer pieces (W-914) with the 2 countersink holes to the long angle piece. On the previous bracket, I put the hole bracket assembly together at one time and found it really hard (damn near impossible) to get these 2 rivets in.

This takes care of the hard-to-get-to countersunk rivets.

You can see here how hard it would be to get to the previously mentioned rivets.

The drawing called out for 3 AN470D4-11 rivets. I looked in all the bins and couldnít find those rivets anywhere. So I decided to use some AN470D4-12 rivets. I grabbed my needle nose pliers and sanded off a little of the ends of each rivet on the bench sander to get the AN470D4-11 to size I needed.
All done!All done!
These brackets turned out really nice.
