Estes Odyssey #7235 Build, Part 13, Vanes Marking & Gluing

I only marked the location of the root edge length of the cardstock vanes (Parts O) These upper pencil lines were just longer than the root edge of the vanes.

Only one of the lines was extended down to the rear of the body tube to glue on the BT-80 tube.

The instructions show all the lines the entire length of the body tube. I wouldn't do this - thin pencil lines can make slight indents down the tube and show up when the rocket is painted. 

That's a lot of pencil lines!

TIP: Never use a ink pen to draw position lines. In will show through paint!

Here's a picture from further on in the build -

Look close and you can see the scribed pencil indent line between the two fins. 

When you draw pencil lines, don't press too hard. Use a soft pencil.

The BT-50 tube (Part L) was glued onto the single pencil line that ran all the way down the tube.

The primer/filler was scraped off and the tube roughed up before the glue was applied. 

The rear of the tube is 1/2" up from the end of the BT-55 main airframe tube.

Here's the forward vanes glued in place. 

Some gloss white was sprayed over just this area to spot any glue that needed to be sanded smooth. 

Notice the edges that had the sanded glue bead (seals) on the outside edges. The edges are smooth and shiny.
