Ok, I've got to build the mechanism for some sliding doors and I can't get my head around it. I figured I'd lock the two wood pieces into some kind of frame and have a curtain pull string style thing going on, but in my head I can see it all falling apart the first time I touch it. Also I'm not sure how pully curtains work, so if you know that'd be appreciated. Unless someones got a better way of doing it. Any ideas?
