1080- Tailcone- p.10-15 step 4-9

Tailcone- 3 hrs 12 mins (Tailcone 45:22, Empennage 220:54, Total 241:50)
Rivet count: 0 (Total 3,686) 

After an hour and 40 minutes, we finally finished deburring after spending just under 7 hours over the past three days. Sort of. After all the major dimpling is done, there are still a few more parts that need to be cut, trim, edged, and deburred as well. The tailcone will require over 7 hours of deburring holes. Insane.

After that was done, we continued by scuffing some of the parts so they can be primed later on. We then dimpled those parts as the directions told us to. Also in there was a random step to enlarge a hole with a Unibit so we can attach the Tie-down eye bolt later on. 

Step 8 on this page directs us to countersink a part to accept dimples, but my countersink drill is already set for a #40 rivet. The next time I work on this, I will be going slightly out of order. I plan to go ahead and work on the next group of parts until they are done and ready for scuffing. That way, I can go ahead and scuff all the parts and get everything really dirty with all the dust that gets created. Then I'll countersink the longerons for #40 rivets since that is where I have the drill set to. After that is all done, I'll come back to step 8 and adjust the drill for this depth height. It's one of the few complaints I have about Van's. Some things seem out of order for no apparent reason. However, that's also the same thing that keep it interesting. There's the "blindly follow directions" aspect of building, and there's the "understand and comprehend" aspect of knowing exactly how each little drill, deburr, and clamping fits in to the bigger picture of getting the project done. End ramble. -M
