(Series to build a Skill Level 5 Estes Odyssey)

In Part 2, the 3 large fins were covered with typing paper, hardened with thin CA glue. There are also 2 small, surface mounted fins. I rounded the leading and trailing edges of those fins, then soaked them in thin CA as well. Next, they were sanded with 220 grit sandpaper and set aside until needed.
Next up is tubing preparation. As a rule, I always try to fill and smooth all external tubes prior to any assembly work. In addition, I always end-to-end sand motor tube(s) and centering rings. I find that paint adheres better to the rough surfaces. I’ve remove tubing spiral with several different techniques, but I seem to come back to the good old spray-on sandable primer in a couple of paint-sand it off cycles. Always works for me. And I’m lazy—I use 120 grit paper in the pad sander to remove the primer, followed by a round of 220 grit paper to touch it up. I put the primer on in 2-3 coats before sanding, so 2 rounds of paint/sand usually gets the tube ready for paint. Oh—my favorite sandable primer right now comes from Advance Auto. It’s Color Match brand. I hate Rust-Oleum Sandable primer—I’ve thrown away 50% of those cans because they clogged, so I’ve learned my lesson.

I cut and taped templates on the 2.5 inch tube and 1 inch tube, then marked them and cut out the fin slots for the 3 thru-the-wall fins. There are also 2 surface mount fins—I decided to next finish the tube, reapply the template, mark and glue them later.
The 2.5 inch tube is visible for inspection on the inside as well, so I added thin CA to the inner spirals. I decided to try a little Squadron Green Putty on those—they seemed rather deep. I only finished the interior spirals as far as you can see them. I also hardened all tubing edges with thin CA for better sanding/smoothing. For the 1 inch tube, all edges were hardened with thin CA, then taper was flattened on the large flat sandpaper sheet, and tubing interior was smoothed with 220 grit paper. I didn't see enough inner tube spiral to warrant filler on this tube.

I used a large sheet of 150 grit paper to rough sand the tapered cuts on the tubes, then laid on a sheet of 220 grit paper for the final pass. It’s important to get the tapers all flat—they are very visible on this kit. Plus, they look cool. Reason enough to do them well.

After thin CA has hardened tubes, edges are squared up with 150 girt, then 220 grit paper.

Now, all tubes have spirals removed and have tapered cuts finished. We can next move to assembling the kit in earnest.
