Estes Skylab #001973, Build, Part 16, Lugs, Nozzles & Final Seam Fill

The two launch lugs were set in position and the outside edges trace with a pencil.

The filler/primer was scraped off inside the pencil lines. 

The lugs were glued in place using Fabri-Tac.

Spraying the outside of the nozzle bells is easy. I also wanted paint on the inside.

Some small holes were punched in cardboard and the pins pressed into the holes. 

The inside of the nozzle bells were spray painted silver.

The spacer ring is glued on the top of the bulkhead.

The spacer ring can end up as a friction fit just inside the washers.

Compress the ring sides to get it to fit while still.

Look down from the top and try to center the tube as even as you can get it.

Or - You can trim the middle side off the washer for a slip fit.

After some white paint was sprayed I could still see some very faint spiral seams.

TIP: I don't normally do this - I sprayed some filler/primer in a cup. This was dabbed on the visible seams.

The right side pic shows it sanded down to surface.
