Estes Mars Longship Build #7296, Part 6, Fin Primer & Card Stock Forming



I was assembling two kits at the same time, you are seeing double inside and outside fins.

This is after the fins got a coat of CWF and sanding. Everything is taped down to spray one side with filler/primer. After that dries, flip them over and stick down again for spraying the other side.



I had to add some filler to the leading edge joint, between the two parts.

The lower picture shows the backside joint which needed a little CWF and sanding.
Three of the card stock pieces need a slight curve to glue over the large ring.

TIP: You should shape the piece over an engine casing, or a large dowel. Something with density.
Press and form the right and left sides under the circle cut outs. If you were to form the curve over the straight lines you could end up with a sharp fold, not a smooth arc.


I like to seal the edges of the thick card stock with a small bead of glue.
On the left the glue bead is being smoothed with the side of a fingertip. After it dries, sand the rounded bead smooth with 400 grit.
