Custom Solar Explorer Build Part 15 Coupler

The two BT-50 body tube sections are joined with a 1" long coupler. I thought this coupler was a little too short.

A 2" long coupler was made out of some scrap BT-50 tubing.
That blue piece was cut from a thin Estes engine mount tube. It made a good gluing tab. The ends will be trimmed and sanding flush after the glue dries.

Here's the coupler glued halfway into the lower section of the BT-50 tube.

Don't glue the upper BT-50 tube into place yet. It will be glued onto this coupler after it is painted red. This makes an easy color separation and a no tape mask.
