Estes Skylab #001973, Build, Part 8, Third Stage Adapter Shroud

Here I haven't glued the cardstock shroud in place yet. It is taped to hold and "form" it to the tube diameters.

TIP: Before laying down any tape - reduce the tackiness by pressing the tape on your pantleg. Press and lift, press and lift. Do this a few times so there is less chance of the tape tearing the card stock when the tape is lifted.

On the right side picture - Note the overlap of the card stock shoulder. This edge will be much thicker when the vacu-form wrap is in place. 

Try to fit the shroud edge evenly over the adapter tube top.

Even though the tape is not very sticky, carefully lift the tape.

Don't glue the shroud in place yet - see the next step.

Here's how the instructions show the shroud gluing.

The gray bands imply more glue than is needed.

I would only apply glue to the upper edge of the adapter - just to the left of the arrowheads in the above drawing. 

Make the glue bead small.

Slide the shroud down and seat the edge on the line of glue.

Then - apply a small bead over the joint, 1" at a time and remove excess with a finger.

This will all be covered with the vacu-form body wrap reduction piece.
