Well, Andrew went shopping today!
It’s been brutal in the shop, so I put up the electric heater I had on the bench and put in its place this new VORNADO. For such a small package, it does a pretty good job of moving air. You have to have it pointed right at yourself though.
Also, I bought the craftsman circle cutter for the large 6″ holes I need in the fuel tank inboard ribs.
i also picked up some 1/4″ and 3/8″ drive drill adapters. I hate having to use a ratchet all the time for bolts. Now I can use the drill.
Oh, and a 7/16″ drill bit for the inboard rib vent fitting holes. The -4 sized AN hardware requires a 7/16″ hole.
Also, I bought a nice little kitchen scale. I thought about saving some bucks and going with the analog one, but I didn’t know if I would be happy not having the digital readout.
Okay, back to work, Andrew!
I broke out the c-frame again and loaded in my tank dimple dies. On all of the other skins, I’d been putting the male die on the bottom, putting the hole in the skin over the die, lowering the female die, and then holding it in place while I struck it with the hammer.
On these skins, I’m flipping the skin over (so the other half of the skin hangs off the front of the workbench toward the ground).
This means I have to have the female die on the bottom, and the male die on top. To avoid my figure-8 dimple from the leading edge, I removed the return spring from the c-frame so any fidgety hands won’t cause anything to move.
(Whiny voice:) My hand got really tired (the hammer is sooo heavy, sissy boy!), so I took a break.
Not sure why I weighed a cleco, but I was curious.
Back to work again. Here’s the bottom half of the right tank skin.
At this point, I had been working for 1 hour and 20 minutes, so I felt like I should find something to do for 10 minutes just so I can log 1.5 in the build log. I broke out the #8 dimple dies and dimpled the #19 holes in the outboard edge of the tank skin.
With a few minutes left, and a new tool just itching to be used, I broke out the 7/16″ drill bit and drilled the vent fitting hole in the inboard rib.
I’ve been following a few threads on VAF recently, and some people are really freaking about about an exact location for this. I followed Van’s directions explicitly, which say “approximate location.”
Ha. I didn’t even give myself a starting mark!
Then, I pulled out the -4 fittings and screwed them in, just to see what they would look like.
1.5 hours. Proseal arrives on Monday. Next week is the black death!
