Lower Ailerons #9

September 30, 2010

Today I only had a little time but spent it trimming the the tapered tip spar and using the left over spar to drill and cleco the tapered part of the spar. I then filed the spar flush with the newly clecoed spar angles.

Lower Ailerons #8

September 28, 2010

Tonight I started with cherry riveting the trailing edge on the lower right aileron. I then spent the rest of the night drilling all the holes to finish off the leading edge install. After 3.5 hours worth of work and very careful measuring I got all the holes drilled and clecoed.

Lower Ailerons #7

September 27, 2010

After thinking how I was clamping the ailerons I decided to take everything apart and reclamp. The idea is to get the nose of the aileron at the center of the radius of the leading edge perfectly so the same amount gets drawn up the sides. The problem is you need a clamp with a 6″ deep grip to do that with how much the leading edge is splayed out. If you pull the sides of the leading edge in enough to get the clamp on the nose and spar you can’t get the nose to sit down tight with the leading edge metal. So I used a piece of wood to extend the edges out past the relaxed leading edge and used two clamps on each side to draw the leading edge metal tight to the nose ribs and tube while I pulled the leading edge metal tight to the spar. This worked better and I was able to drill my first holes. I drilled the holes for each rib on both sides and then I started drilling the holes inbetween the ribs but it was getting late. Again not so many pictures because of the lack of more than two hands but here is the picture after got the first holes drilled and clecoed. I removed a bunch of the clamps so that I could more easily work and mark holes. I also made the trailing edge braces to support the trailing edges on the right lower aileron.

Lower ailerons #6

September 26, 2010

Tonight I drilled the trailing edges of the lower ailerons. I did this by setting the trailing edge at 1/4″ past the end of the rib and then using my square I measured the distanace from that to the spar and then just set the rest at that distance so that the when the trailing edge is straight so is the spar and vice versa. I will rivet those in place with some cherry rivets tomorrow. I then started to tackle a good method to install the leading edges. I think I found a method that will work. I took my 6″ bar clamp and a peice of 1 1/2 by 3/4″ wood sticks I had lying around and started bringing to the two ends together. I then used a straight piece of 2.5 X 2.5 in aluminum angle clamped to the the tails with 1-1/2 by 3/4″ wood to keep the twist out of the aileron. I then forced the nose into the radius of the leading edge using wood on the spar and my bar clamps in multiple places. As I got the leading mostly drawn tight I used my bessie bar clamps to clamp down the leading edge so that it sat flush with the spar. I had to employ the use of my wife as it takes a few hands to do this (the leading edge is strong). I didn’t take to many photos as I need all my hands and legs to get this to work out. In all I used 18 clamps to do this. The good part is I was able to move the wood sticks down far enough that I can still drill the rivet holes. Tomorrow I will start drilling and clecoing everything together.

Tonight I took the ailerons over to the airport where have access to a air compressor and pneumatic squeezers. I quickly got to work deburing the tails and nose ribs and clecoing them in place. It took 4.5 hours but I was able to buck all the rivets into the ribs and the doublers. Rinse and repeat from the uppers. Now the uppers and lowers are pretty much in the same condition. So now comes the dreaded install of the leading edge.

Lower Ailerons #4

September 13, 2010

Tonight I started in on drilling the left aileron nose and tail ribs to the aileron spars. I then marked and cut the aileron ends and clamped the aileron tips to check the fit. I so trimmed the tip bows to fit and the aileron trailing edge to fit. I still need to cut the taper all the way up the full size spar but that can wait. Tomorrow I will debur and rivet the nose and tail ribs to the spars along with the doubler plates.

Time spent tonight 3 hours
Total time spent 232 hours


Lower Ailerons #3

September 12, 2010

Tonight I set out to bring the right side ailerons up to the same progress as the left which ment drilling and installing the aileron hinge brackets. Pretty much rinse and repeat of a couple of days ago. I then decided to start drilling the nose and tail rib rivet holes for the right side and managed to finish that side. So all I have left before riveting is to finish the left side drilling of the ribs and take both of them to the airport for riveting.

Time spent today 4.5 hours

Lower Ailerons #2

September 10, 2010

Tonight I continued the aileron building by marking each hinge location on both ailerons and then marking the centerline of the spar. I then marked the center lines of the bracket and drilled the three hinges brackets for the left aileron. I then back drilled the doubler plates for each hinge bracket. I tightened everything up temporarily to check the fit, and it fits great. Next time I will bring the right wing up to speed with repeating the same steps I did today.

Wing swap and lower ailerons start (2 day roll up)

September 7, 2010

Tonight I decided I have done just about as much as I can for now on the upper wings and need to bring the lower wings up to speed with the uppers but in order to do that I need to get them off my table so I could work on the lower wings. I had some left over boxes lying around so I used those to prop the wing up on to get it out of the way while I worked on the lowers. One side note I noticed that the glue strip in the upper wing center section kinda protruded up above the rib slightly so I took the planer and brought it back down so it matched the contour. I test fit one of the wooden leading edges to make sure and all was well.

Back to the lower wings…I set the lower wings up on the racks and started laying out the lower ailerons. I used the same amount of ribs as the up which will result in slightly closer aileron ribs spacing since the lower ailerons are approx 4 inches shorter than the tops. Anyway I set the spacing of the ribs and when I was happy I marked their locations and then set the other side to the same exact dimensions. I again used a 3/16 spacer between the root rib and the aileron. I then spent some time temporarily tightening down the hinges so they wouldn’t move while I was setting the aileron ribs. Next up will be marking the aileron spar centerline and marking the locations of the nose ribs and doublers. After that I will get to drilling and riveting and that will bring the lower ailerons up to the same status as the uppers.
