Elevator is 97% finished!
The elevator is now basically complete. The only things remaining is to install the connector on the trim servo motor, fastening the tip lead weights and 4 mk-319-bs rivets that I'm short of. I will receive the Micro Molex crimping tool from Stein Air tomorrow, so that I can complete the servo motor wiring.
Next I'm going to do as much as possible on the fairings (chapter 12) for the vertical stabilizer, rudder, horizontal stabilizer and elevator.
I did have to extend the handles on the blind rivet tool be some square steel tubes (28x28mm). |
The extended handles made squeezing those aft rivets easy. |
The servo trim opening from the inside. |
I used two small 3 mm nuts to reach two rivets on the trim servo attachment assembly. |
I was a bit inattentive when setting the rivets on the left root gusset, so I got a small dent below the rivet head. I just worked it smooth with Scotch Brite pas and applied primer again. |
Riveting the front spar. |
Ready to glue in the foam bars. I bought the 3.5 oz tank sealantfrom Vans Aircraft . It's a kit with the accelerator in the same package. I used the battery drill to mix it. |
Sticky stuff! This is the trim tab. |
I used a piece of wood to keep the skins apart while positioning the bars. As the sealant is sticky, they stays pretty much were you put them. |
All done, and weighted down. I let it stay for 2 days before riveting the trailing edge. |
The servo is riveted in place. I did a quick test with a 9 volt battery. It worked! |
The lead weights cut. I used the band saw to rough cutting, and than sanded with the belt sander. |
Some adjustment was necessary. The holes didn't align perfectly. I didn't fasten them at this stage, as I will wait to after that the fairings are adapted. |
I spent some time mounting a tool board to keep things a bit more organized. |
The trim tab is ready for rivets. |
Straight trailing edge😀 |
This is how far I've found is ok to roll the leading edge. Rest has to be done by hand. |
I created a bracket to hold the tube down while rolling. |
I found it necessary to use a clamp so the clamp didn't raise. |
Finished rolling and hand squeezed. Still some millimeters to go. |
Both elevators finished and the trim tab attached. |
