Estes Patriot Build #2056, Part 5, Coupler Bulkhead
I'm using the yellow section as a altimeter and payload section.
I'll have to make a coupler with bulkhead out of the second red coupler.
The red coupler fit can be tight so the edge that goes into the lower BT-60 section was rounded on the outside.
After rounding the edge got a coat of medium CA.
The edge was smoothed again with 400 grit.
Here's how the red coupler will fit into the upper white tube.
The coupler isn't glued in yet.
The red coupler is 1 1/2" long.
Instead of gluing it just halfway in, I want a little more length into the lower white BT-60.
5/8" will be glued into the upper yellow section, leaving 7/8" below.
A pencil tracing was made on heavy card stock around the outside diameter of the coupler.
This matte board is thick but can still be cut with scissors.
CA tube ends = 5 minutes
Trace and cut disk = 5 minutes
Total build time so far = 1 hour 10 minutes
