Finished the (1st) Left Flaperon Today
Was a bit concerned yesterday in setting the rivets on the A-1207-L actuation bracket. What worked well what was on the suggested tool list. I used the 1/8" rivet x 1/2" tall cupped squeezer and was able to set the rivets, even though they were quite close to the web of the bracket. Suggest to all to ensure the bracket is as close as possible the inboard nose rib and bracket assembly by inserting the AN3 bolt (not supplied) and using a nut on the other end to squeeze the 8 washers. (My suggestion, not Van's). Then match drill per the instructions, after, of course, ensuring the brackets are 90 degrees to the spar. Attached the pivot bearing brackets and continued with assembly.
The remainder of the flaperon went without a bit of a problem. Follow the instructions and the instructions as shown in the FIGURES. Had to touch drill one on the holes in the counterbalance but otherwise all of the holes in the skins lined up just perfectly.
To form the trailing edge skins of the flaperon, I bent them ever so slowly using a piece of 8" x 24" plywood with a short nap towel between the piece of plywood and the skin. If you go slowly, and use this method, you will get a nice bend to match the A-1205 main ribs and you will not end up with your handprints in the skin. Suggest starting with the bottom edge of the skin up. Go Slow! Do not press on the left or right edge of the plywood, do not put a crease in the skins. Go slow!.
Attached and riveted all of the trailing edge skins. Ensure you are hitting the ribs by feeling with your finger or using a flashlight. Then attached the nose skins. Follow the instructions when match drilling the A1210-L and R nose ribs. Ensure they are 90 deg to the spar, match drill with a #40 drill, insert a 3/32" cleco as you go and then match drill with a #30 drill inserting 1/8" cleco's as you go.
First flaperon is now complete. Looking down the edge, it is absolutely straight with no hint of twist. One more day (hope to finish the 2nd flaperon) and I am out of work! Where is the next kit?
