Estes Doorknob, #9720 Build, Part 5, Nose Cone & Body Tube Seams

TIP: Always check the nose cone eyelet. With the eyelet removed there can be rough mold lines. These rough lines can wear and possibly cut through the shock cord.

This picture shows the before (rough) and smooth (after).




Lightly smooth any rough mold lines with a small flat file.
The body tube had a rare "double" seam. The clear glassine top wrap had shrunk into the lower seam gap! I marked it with a pencil to show it.

In the past people have wrote about removing the clear wrap, I wouldn't recommend doing this. You'll end up with more work trying to fill twice as many seams!

I did use the pencil to press and indent the shrunken seam where it was deepest.

Note the normal seam below the pencil line.



The normal seam was filled with CWF.
The wider (shrunken in) double seam also got some CWF filler and sanding.
In the picture to the right, the seam at the top and bottom is the shrunken glassine seam.
Between that is the normal body tube seam.

    That's a good tip about pressing the extra seam in with a pencil. Since they're so wide and shallow and harder to fill properly, on bigger tubes with those sunken seams, I've always just kind of lived with them. But they bother me.

    I'll have to try that on the next build.
