This is actually my first try at hinging doors. I've been out of modeling for over 13 years, and just got the bug again last year. I had some old doll house piano hinges that I was going to try years ago. There are two of these type hinges on each door, with plastic rod cut to match the hinges between them to look like one continuous long hinge. I am not completely happy with the results, though they function well. Most of my models are learning experiences by trial and error. The Paystar that Sam is building has a good example of a first class hinge job, I will be trying that method the next time that I open doors. As most of you have noticed the sleeper is from the Ertl 4300 International, which already had opening doors on the left side. Thanks for the comments..Brian
