Estes Saturn 1B, #7251 Build, Part 14, Display Engines

Before gluing the nozzle spacer tube onto the low plate - 

These can be hard to center accurately. Center it visually, then trace around with a pencil.

Check to see if the circle tracing is centered. If not, make adjustments, erase and trace again.

The plate with the holes glues on the other side of this plate. 

TIP: Before gluing the tube to the plate - 

Sand the tube edge flat. Tube edges are typically cut at an angle. Sand the angle flat and you end up with a little more gluing area.

Now glue the tube onto the flat plate on the pencil line. 

I sprayed the nozzles silver before gluing them onto the low disk.

There are eight nozzles, it'd be hard to get paint in all the recesses.

To get full paint coverage inside the nozzles, I sprayed some silver paint into a small plastic cup. A Q-tip was dipped in the paint, the paint was swirled inside the nozzle.

The bottom nozzle plate was sprayed with silver paint.

Both sides of the nozzles were sprayed so the paint on the glue surface was sanded off.

The four smaller nozzles glue into the center first, then glue the slightly taller nozzles on the outside.
