I have started to rebuild my home office and due to a shortage of space have to have a 3-section desk. The first is fixed in place over the top of the void above the stairs with supporting cupboards underneath. The second piece (the one in question) will need to hinge upwards (too long to hinge downwards) to allow for an extending bed used occasionally. The third is not in question here as will be clip on so easily removed and light use.
My question is, how best to hinge this piece of desk. The desk is 25mm thick laminated MDF, the framework below is 18mm Laminated MDF. I obviously want the two pieces to sit close together, and thought about attaching a protruding 18mm piece of wood to the fixed desk and using full overlay cabinet hinges (6 of) that way the weight of the desk when closed would rest on the wood rather than the hinge, and it would only be opened about 6 times a year when people visit.
But if anyone has any better ideas...I would happily listen right now.
