New "compound" crossbow attempt looking for suggestions First post and first serious attempt at making a crossbow. Not sure if this counts a a slingshot but I figgured you guys are the people to ask. Recently started working on an idea for a small width pulley crossbow. Just wondering if anyone has ideas for improvements. I have the bones of it complete with a working trigger but I'm not sure how to make the arms move in unison to keep the shot straight. Any thoughts would be appreciated.
