Glue the insides of the flaps of the vertical beams, and place them over the sides of the base, lined up with the holes in the base.

Thread the first cocktail stick through before the glue dries, to make sure the holes are lined up. If you leave it in place, you can glue on the diagonal beams before the glue dries.

Glue the inside of all the flaps of the diagonal beams, and place them bracing the vertical beams against the base.

Place the throwing arm between the vertical beams and thread the second cocktail stick through to hold it in place.

Take a length of sewing thread, double it, and knot the ends together in a nice, fat, ugly knot. Tape that knot against the vertical part of the throwing arm, against the pivot section.

Use the needle to thread the thread through the holes in the end of the base. The thread also needs to go around the lower cocktail stick, but it is easier to pull the stick out, lay the thread in the base and then put the cocktail stick back, trapping the thread below it.

I happened to have a drink-can ring-pull lying nearby when I made this, so I tied it to the end of the thread to give me something to pull and to stop the thread getting pulled back through the hole.
