That is the code to see how I made small hinges, 1/4" square.
Or go to paddleducks, construction, Duke of Devonshire, page 20.

Do a search for "dolls house fittings" there are some superb miniature brass hinges readily available, all they need is the odd strengthener added to suit. I looked at making my own hinges up from scratch, but with all the separate items involved, soldering them all together was going to be a nightmare as no sooner you fix one item, the heat would melt the solder off it when attempting to add another piece.
