my original idea: (Spoiler- highlite) take the gas out of the bulldozer and fill the Oxy-gasoline torch (Heat), remove a peace of bulldozer for anvil, forge 2/4 in. bar (mild) into arrow heads, cut 2ft. segment of spring steel and file noches, Saw gunstock blank out of 12 X 2, forge U-nails out of some 2/4 in. bar, make bowstring out of 550 cord, forge/bend a trigger mech. out of last of 2/4 in. bar, put it all together and you have a crude crossbow. Or you could just forge a knife and make Snares...
