One of the few advantages to having built a few kits before doing ARFs is that you accumulate tricks and techniques and tools that make ARF building easier. Maybe it's the bang your head on the wall concept too, Arfs are easy when you compare them to a kit. Anyway, for CA hinges, cutting a little of the corners off helps get them in the slots. You should cut away a thin sliver of covering from around the hinge slots to let the glue flow in properly. If you cut up some bandaid sized pieces of newspaper you can use them to wick away any excess glue. How you hold the parts and the glue bottle and using the right tip on the bottle all help. Also, I have an electric hinge slotter which quickly fixes any slots that are too shallow. Even with good technique and esoteric tools, it takes time to make nice hinge joints.
