I installed these MDF saloon doors to a skincare specialists in London, using a fantastic method of end grain fixing I found here http://www.ultimatehandyman.co.uk/forum1/viewtopic.php?t=87420&start= I used the dowel through the board from face to face and it really works. It was a nice job for me because I specialize in joinery as part of my handyman skill-set.
The Method
The doweling method is so strong I was able to hang the bespoke doors to the end grain of the MDF and the existing cupboard which I assume is also made of fiber board. What a neat trick, and what a neat little set of doors if I say so myself. I watched this video before embarking on making the doors. I would love to make something so elaborate but that can't be done for under £150, whereas these doors could! https://www.youtube.com/watch?v=I299V5XHslw
The Hinges
Another brilliant bit of hardware I used to hang the doors is the double action sprung hinge https://www.toolstation.com/double-action-spring-hinge/p81040.
