Estes Skylab #001973, Build, Part 5, Third Stage Adapter

NOTE: Save the centers from the centering ring for Step 5 of the instructions.

Notice the ring in the right picture. The ring is set inside the edge of the 1 3/8" long tube.

 

GOTCHA: The instructions say cut a 5" length of shroud line. In order to double and tie it easily - cut a length of at least 10".

I used #10 embroidery thread which is much stronger than the current shroud lines supplied in the kit.

Use tweezers to make the knot tie easier.

Here's the fit of the adapter of the in the top of the tube.

I did have to sand the adapter for a better slip fit.

The tube seams were first filled with CWF and sanded to surface.

The picture on the right is a fairly thick coat of Duplicolor Filler/Primer in the second step of the seam fill.

This shows the saved ring center glued in place.

I also treat the low adapter corners (at the top here) with some CA glue applied with a Q-Tip.

After that glue dries, round off the edges with some light sanding.

This makes it easier to slide in the upper section later on. 

If the adapter edge is smooth and rounded it won't wear or peel the inside layers in the lower body tube.
