Han circles the junkpile, tappin the stylus on his readout. He drafts a quick, counter-weighted design, and the readout beeps its approval.

Setting to work, he finds an old hammock which he cuts in half for the sling, a couple of poles, a frame of something and an abandoned weight set.

He sees some cloth and duct tapes a sign that reads "My pumpkin rode the shop-class trebuchet"
