Ok, so first I’ll apologize as this timelapse is all over the place. Well, honestly I was all over the place as I ended up making a few errors as I have been juggling a few things.
Getting ready to rive the rear spar to the wing ribs I deburred and primed everything. I then began to cleco everything together and was trying to utilize my squeezer to set the rivets for the rear spar. Honestly, this didn’t really work all that well as I still was going to use the rivet gun for a sub-set of rivets. Also it was just plain difficult to get the proper angle to even come close to setting the rivets correctly.
After setting a few rivets, I realized I had not dimpled some holes:
Page 15-4: Step 3 – “Dimple the holes in the ribs lower aft tab and the holes in the W-1007A-L Rear Spar Web lower flange that correspond to the tabs.”
After looking at these locations to see if I could use the squeezer or some other method of adding the needed dimples, I realized the best solution was to remove the offending rivets attaching the rear spar, correct the oversight and re-rivet the parts.
- This is a great lesson to learn. Take your time and re-read the directions.
- You can fix just about any mistake and you will make mistakes.
- Removing rivets is a skill you really need to learn 🙂
Here is what you get after removing a bunch of perfectly good rivets:[inpost_fancy thumb_width=”200″ thumb_height=”200″ post_id=”629″ thumb_margin_left=”0″ thumb_margin_bottom=”0″ thumb_border_radius=”2″ thumb_shadow=”0 1px 4px rgba(0, 0, 0, 0.2)” id=”” random=”0″ group=”0″ border=”” show_in_popup=”0″ album_cover=”” album_cover_width=”200″ album_cover_height=”200″ popup_width=”800″ popup_max_height=”600″ popup_title=”Gallery” type=”fancy” sc_id=”sc1532462583210″]
With the rivets removed and the proper parts dimpled, I re-rivet the rear spar to the ribs again. This time with less errors and in a much more comfortable position!.
I then begin to prep the rear spar for the right wing by removing the blue film and drilling the doublers. I also fabricate the doubler with the cut-out for the pushrod using a few different tools. Honestly the file is still my “go to” tool for this kind of stuff.
With all the doublers fabricated, I attach everything to the rear spar so I can match drill.
