No, you put that wood arrow into a weapon trap, silly. Then release an untamed groundhog where it will run over the weapon trap.
Bonus points if whatever creature you release over it survives and heals.
edit: alternate idea: chain a crippled tame animal over the weapon trap, if the animal has an injury that makes them occasionally stunned. Better if this is a crippled kitten, or some other tiny, harmless animal. Otherwise, go with one of your own crippled dwarves, in a 1-dwarf squad, sitting over the weapon trap that will shoot him with the ultimate platinum class deluxe arrow whenever he gets his stun effect.
In this case, bonus for what qualifies as a miniaturized megaproject whose sole purpose was to kill a single one of your own dwarves who probably would have died of his own wounds, anyway.
The ultimate expression of Dwarf Fortress: To spend several years meticulously searching for and hoarding every item type in the game, putting them all together with the greatest of craftsmanship, and using them for the sole and specific purpose of hurting yourself in the least efficient manner dwarfenly imaginable!
edit again: Susquipidalian Locquaciousness bonus points for crippling the dwarf yourself just to qualify for the previous challenge. Hurting yourself on purpose in a roundabout way to be able to hurt yourself in an even more elaborate and wasteful manner is the sheerest essence of all that is dwarven.
