I broke my old bow seeing if my sister could use it.(was trying to loosen the draw, and went past the nut) Actually no broken parts. Should we try and re-assemble it or take it to the bow shop. Its a pretty crappy bow..

If the limbs were still under a good deal of tension when you hit the end of the bolt, you'll need a bow press to put it back together.

Do you know how the strings/cables run? As long as you don't suspect damage, and you can engage the limb bolts without a press, I'd go ahead. If you need new strings or cables, might just as well take her in.
