Estes Saturn 1B, #7251 Build, Part 25, Painting Lower Body & Gluing RCS Nozzles

The black areas on the lower body has been outlined. 

Notice the interior surfaces have been masked. If paint got on the inside of the scalloped shroud, it might drag and mark the white tubes when the shroud is slid down from the top. The fit of the scalloped shroud over the tubes is very tight.

On the right - the full mask leaving the black areas exposed.

I purposely took this picture with light reflection on the black Sharpie border line. There is a slight difference under a bright light. This will go away when the model gets a flat finish clear coat.

Back and forth in the instruction order - 

I applied a drop of Fabri-Tac glue to the center pin area on the underside of the nozzle piece.

This drop was spread out with a toothpick. The trick is to use enough glue to hold the nozzle piece in place, but not too much that the glue could squeeze out on the sides of the body tube.   

Some medium CA glue was squeezed out onto scrap cardboard. 

Some glue was picked up on a toothpick tip. The glue was transferred to the pin on the inside of the body tube.

Build time:

Mask & Spray Low Section: 20 minutes

Touch up low paint: 20 minutes

Glue on RCS Nozzles: 15 minutes

Total build time so far: 19 hours, 45 minutes
