First thing after today’s realization that I had forgotten to dimple before priming, I rushed home and grabbed the tank dies to prime the #40 holes.
No problem to dimple after priming. (There was a little bit of twist after dimpling, but no big deal, the rivets will hold this thing together.)
The only way you can tell I dimpled after priming is that the dreaded dimple circle is visible, because the outer edge of the dies mars, (maybe polishes?) the primer a little. You can see it in the pictures.
Here’s the other side.
After I finished both, here they are on the table. Crisis averted. (Not really, I would have just re-primed them.)
Then, inside to grill some dinner, then back out to do more edge finishing, cleaning, and priming. I grabbed R-606PP and R-607PP (lower and middle spar reinforcements) along with R-617 (shim) and finished the edges with the scotchbrite wheel. Once complete. I took them inside, cleaned them with dawn detergent, and brought them back out to dry and prime. Here’s a priming shot.
Next, I looked around and grabbed the R-912 counterbalance rib and did some edge finishing and dimpling. Here’s a dimpling shot.
Same deal with with the R-903 tip rib and the R-710 horn brace. Here’s the horn brace.
After the primer dried on the three pieces I primed tonight, I put them back on the table and examined my progress. Still a long way to go.
Enough work outside for the night. I grabbed the soldering gun, my wooden straightedge, and the R-913 counterbalance skin and headed inside to devinyl.
I decided to leave some of the vinyl on here to save on primer on the inside and protect the finish on the outside. I think the amount of primer weight I am going to save by masking with the vinyl is minuscule compared to the parts I will inevitably need to re-prime. But, if I pulled off all the vinyl, and primed the entire interior surface, I would always know I was carrying around more primer than I needed to be. (It’s all about figuring out what you can sleep with at night.) While I am sure I will add more than plenty of unnecessary weight in other areas (all of the nutplates I am going to add), not doing this would make me feel lazy.
Next, I grabbed the R-901-R (right rudder skin)0 and pulled it inside to devinyl. Notice on the left that I made the cuts on the trailing edge (rudder is upside down in this picture) but haven’t pulled off the vinyl? I am going to leave the vinyl on while I prime the rest of the bare metal areas, then remove the trailing edge vinyl. This area doesn’t need to be primed, as it will get scuffed up with a scotchbrite before using Pro-seal to glue the two skin trailing edges and trailing edge wedge together.
Next, I flipped that bad boy over and did the exterior. Here’s a shot before I’ve pulled some of the vinyl off.
Repeat for the left skin, and then I took both back outside and stored the left skin on the top shelf of my second toolbench.
And a finished shot of the right skin, back out on the workbench.
I was using the clock in the kitchen to mark my progress, and decided I was going to stop at 9:30pm to head to bead…except (yeah, you know where this is going)…I forgot to reset that clock after the time change. It was actually 10:30pm and I had put in 2.5 hours. Great for airplane progress, bad for my sleep debt. I’m not going to put in any time tomorrow, need to catch up on sleep. See you in a couple days.
