On the MDF front, my personal opinion is that it is quite unforgiving to mistakes. If you cut everyting perfect and square and you support everthing correctly its great but ... IF you get something a little out it is quite difficult to tweak back without making it look a massive mess. This is speaking from a firm basis of many many mistakes with MDf and inaccuracies. I must confess that I have never used MR MDF so I will try that on my next project. The fuzzy edge problem does leave me a little frustrated at time as well..

mr will definately help with your fuzzy edges   interesting that the latest F&C has an article about making a library using veneered mdf with maple lipping, and no spread farther than 850mm. certainly my old units are no wider than 600 and have stood up for a long time. good square cuts, and biscuits plus occassional spax screws and to be really safe  the back should be screwed on to the outside to ensure square and also hold it all together properly. and of course a decent glue  paul  |

Never had a problem with supporting books with MDF or any other thin material . You just need to support the load I.E. Lip the edge . These are supported on four shelf supports and the front edge lipped with 45mm oak .  |

Hi everyone, On the subject of MDF, I thought you may be interested in a job I completed recently.    Mostly in MR MDF but with fluted pillasters in tulipwood and the work surface in brown oak. Painter supplied by the client (thank goodness). On the subject of stiffness, as has been said you have to design with the limitations of the material in mind. Fixed shelves, effectively held in tension between the sides, and screwed to the back from behind can span reasonable distances without sagging lipped or not. MDF is excellent for this type of thing, should last indefinitely if properly constructed and is one of the most environmentally accountable materials we can use. |

Thanks jfc and gazza.
Yes, it's a fabulous house. Renovated/extended farm with lots of oak framing work. Such a pleasure to be involved with a project like that.
