Estes Sidekick #7287 Build, Part 3, More Ring Prep and Tri-Fold Mounts

The launch rod hole was rounded using a sharpened dowel. Press lightly and rotate the dowel.







The outside edges were sealed with some medium CA. After it dried  the edges were sanded smooth.

For an easier, cleaner fit over the body tubes, the interior of the rings was burnished with a smooth, sharpened dowel.








A Tri-fold shock cord mount needs to be FLAT in a small diameter BT-20 tube. Notice the angled pencil marks. The shock cord is initially glued on the mount at an angle. After it is folded twice you aren't dealing with a double rubber thickness plus the stacked layers of a folded mount.
