ASP MMX Micro Corporal Build, Part 4, Engine Block, Coupler & Nose Weight

1/4" is cut off a coupler for an engine block.

The Kevlar shock cord is tied around the engine block.



Mark the other longer coupler at 3/4".
With a thin dowel, apply some glue inside the end of the long tube.
Push the engine block into the tube (and glue) up to the pencil line on the coupler. Remove the coupler.

Feed the loose end of the shock cord through the shorter coupler.
The split shot nose weight is tied to the other end of the shock cord.

The lead weight could slide down and through the coupler tube. The instructions recommend epoxy to set the nose weight at the top of the coupler.
