Default RE: BVM Electra Build

Before glassing the wings a 3/8ths wide strip of 1/64th ply was added to the top T.E. of the wing to provide a hinge line cover. This is not part of the kit but I have been doing this for years.

All of the wood structures have been glassed with 3/4 oz cloth and West Systems epoxy resin. After te epoxy dried, they were sanded and then primed. Filler was added where needed and the structures were sanded again, removing most of the primer.

Panel lines were drawn with a pencil. 1/32nd Chart Pack chart tape was laid over the drawn on lines and the inspection covers were placed on the wing.

A couple of light coats of primer was sprayed over the entire structure. Then a couple heavy coats of primer was sprayed over the chart tape. After the primer dried, the chart tape was removed.

The next step is to add the rivets. These will be burnt into the primer using a low amp soldering iron with an attached 1/16th brass tube. Photo 1 shows the tools I use; a soldering iron, a thin brass strip with holes drilled, and a Top Flite Warbird template. As you can see, the tempate includes rivet spacing for 1/7th through 1/3rd scale and various shapes to make inspection covers. I used the template to drill the holes in the brass strip.

Lines were drawn where I wanted to add rivets that were not next to panel lines. A low amp soldering iron with an attached 1/16th brass tube was used to burn the rivets into the primer. After all of the rivets had been burnt into the primer, the suface of the was wet sanded with 600 grit in preparation for paint.
