I hope I have the right place to ask for help. The model is Constructo's Elidir. Of course I'm bashing the heck out of it. I got myself painted into a corner, There are two sets of double doors, one forward, one aft. The for'd doors are glued closed. The after doors I want to to have swung open. The problem is how to fasten the doors. They are too thin to drill a post top & bottom. Any suggestions?
