Interstage/S-IVB/IU Masked

Finally, I think I’ve found and masked all the little things that need masking on the Interstage/S-IVB/IU structure. The ullage rockets, the retro-rockets, the reflectors, the antennae, the roll pattern. I thought I was done yesterday, and then realized that there were myriad (well, not literally, but it almost seemed that way) small things on the IU, at the top of this part of the stack, that shouldn’t be black. And then there was trying to figure out if there were any significant, visible differences between the drawings I have (of Apollo 11’s stack) and Apollo 15’s rocket.

I’ll be able to spray the black tomorrow evening if things go really well. I suppose, if I miss tomorrow, that it’s worth missing Friday to hear Chuck Yeager, though!

Next up (already started, in fact): masking the S-IC/Interstage/S-II complex. It’s not as dirt simple as it looked at first: in fact, besides the various large structures (fairings, vents, etc.), there are a bunch of little antennae to mask…
