Custom PONG Build Part 3, Coupler Assemblies

From the last step, set a small weight over the tube, ring and paper until it dries.

Run a ring of glue inside the other end of the BT-50 tube.

Repeat the last step. Set a light weight over the assembly and let dry.

On a Q-tip spread a coat of medium CA glue over the dry paper ends and coupler.
This will harden and strengthen the ends.
Don't worry about the BT-5 center hole yet.

With a sanding block, take down the hardened edges.
Sand at a very slight angle trying not to sand off the yellow coloring on the tube.
Sand on side at a time. The paper will flex and eventually sand off.
