Estes Saturn 1B, #7251 Build, Part 9, Tower Assembly

I'm not building in the order of the instructions. I'll be bouncing around a bit -

    

One side of the tower has alignment pins,

The other side has alignment holes the pins fit in.

TIP: You can sand the side with the alignment holes a little smoother for a better fit of the two sides.

Only sand smooth the side with the holes, not the pins side!

The resulting fit is subtle but better - 

On the left is the dry fit before sanding the "hole" side.

On the right is the better dry fit after sanding the one side of the assembly. No glue yet!

You have to glue the ring inside one side of the tower before gluing the two sides together.

It helps to use tweezers -

Liquid cement (in a bottle with the brush attached to the screw cap) works best for a tower assembly.

You can hold both sides together - 

Then brush the outside down the seams. After the glue dries, lightly sand the glued seam with 400 grit sandpaper.

Build time:

Glue up tower - 20 minutes

Total build time so far: 6 hours, 25 minutes
