RE: time for hinges
I used to use CA hinges and never had a problem, even on a 1/3 scale model. I hate risking dripping CA or fuming the covering.
I use Robart hinges now and think they're more professional looking and easier to install. Drill a 1/8 hole and counter sink it a tad. Glue them in with gorilla glue and they don't come out...use epoxy and they might come out.
