Old Victorian house, two living rooms divided by two large doors (2.5 x 1m). Doors are solid wood, four panels with cross bars (10cm). They are a bugger to open so I'm thinking of making them into bifolds by cutting vertically down the centre bar and adding hinges. Would this work? I'm worried about the weight being too much for the divided plank which will end up only 5cm wide. And would I need to add floor bolts half way along to keep them stable when closed?
