Forum:Willowtree help: machine pistols

Im pretty new to willowtree, but have manage to make some pretty sweet gearbox smg's. Now i want to make some machine pistols, but everything im trying is either not working, or the guns turn out crap. Can someone who is good at willowtree show me some codes for stuff like a powerful thanatos, or a gearbox machine pistol. Any help would be appreciated. thanks.
