OR Spaced Needle Build, Part 4, Coupling The Tubes Together - The Better Way!

Here's how the coupler was made on the new version of the Spaced Needle design to allow the model to break at the middle at ejection and for easier transport.




A pencil line was traced around the brown coupler onto some matte board.
The initial cut was made with sharp scissors. It's not a perfect cut, it'll be cleaned up after this cap is glued onto the coupler edge.

Two holes were made using my rotary punch. A Kevlar loop will be tied through the holes.







A strip about 3/16" wide was cut from the matte board.
This will be a reinforcement band going over the top of the disk.
You can see the strip in the next picture.

A bead of glue was applied along the inside edge of the coupler.

The punched disk with the reinforcement strip is glued on the coupler edge.
