Ron,
I cut the joint flat then file a v-notch in the end. Sometimes I'll drill and pin the joint as well
I typically use liquid cement (Testors is my personal favorite) but have also used super glue.
I also like to dissolve bits of scrap styrene in Plast-I-weld and brush it on the joint like metal weld. After it's has setup I file to joint to shape very similar to what you might do in a 1:1 application.
I create the bends using my fingers or round needle nose pliers - then holding the bend in my fingers heat the joint over a candle flame to set the shape.
