The photograph is so clear that it’s relatively easy to see how Jeff built the piece. Jeff also provided some useful notes on the construction:
“I built this … piece … because .. all the ones I found were too large for the stand. I constructed it from square stock bass wood, wire, string, and paper. The sling arm is made from wire wrapped in string. The basket is made from a cut out piece of paper "under laid" with string and "glue wrapped" over a large rock.”What’s amazing is that Jeff reported that, before the launching ropes were glued down, the model fired. Well done Jeff a nice piece.
