Converter stuck in cranksaft!

How are you guys installing your converters anyway? I found the best way is to stand the tranny upright. It makes for a BIG mess though. When I try to slide the tranny on laying flat I seem to have a hard time getting it seated.
Once you get it on the first "row" do you just have to keep turning it till it fall into place, or do you have to keep removing it and trying to set it in place?
