Step 2: The materials

Picture of The materials
For the model showed in Step1 the materials are:

4 sticks of pine of 240 cm by 5 cm by 6 cm (5 is front; 6 is deep) (photo1)
6 selves of DM of 240 cm by 22 cm by 3 cm (photo2)
4 wall metal peg screws to hold large weigths (one for each stick) (photo3)
12 regular wall plastic peg screws to hold medium weigths (three for each stick) (photo4)

There is also LDF and HDF (Low and High density respectively) particle board. The difference between LDF, MDF, and HDF is the size of the particles. Smaller particles are more densely packed, and there are more bonds between particles to contribute to strength. A Caution with using particle board is that it can bow(and snap) if too much weight is added, so for a shelf with textbooks (or other heavy shelf worthy things) you could try: A) Using real wood(wood has a grain which gives a boatload of strength - try bending a box of straws) B) Laminating(Glue) two sheets of the particle board together C) Laminate two Sheets together, and add a bar of steel(usually sold near the nuts and bolts aisle at Home Depot and Canadian Tire - possibly other hardware stores too). You would have to use a router to create the bevel so that the sheets would be flush, but that would drastically increase the strength along that stretch of the shelf, provided that there are at least 2 joist(vertical) supports across that stretch

Did you specifically choose softwood for the vertical supports, or would anything work? I wonder if hardwood (like oak) would be safer/more durable.

Hi jeff-o, Anything will work. I chose softwood because I were short of money the first time I did it but the ones in the photo of step6 are made with some redwood much stronger and dense. For sure oak will last longer and will give a much more beauty look to your selves. Good luck! and post the results.

Hmm This type of shelves (though more solid) have been for sale on the Swedish market for many years, sold by Sparring (the innovation company) and IKEA. (a simplified model).

If you're trying ot buy the materials at a Home Depot or similar store then ask them where they have MDF. Thats the actual name for the material here.

Hey urm.. sorry to souind a bit thick.. But WTF is DM Wood?

Please reply soon! I really wanna make these =P

juliofo (author)  Krispy1018 years ago
Hi Krispy, This is not the fast reply you asked but it is that I do not visit instructables as often as I should do it. DM is the name in Spain for Maximun Density, it is not actual wood but a kind of brownish cardboard or powder particle board made with dust of wood and formaldehide (i think). It is heavy and bends very much, so use the thick one (from 1 inch thick up) and do not make shelves without support longer that 60 centimeters or 2 feet). hope it helps although late best julio
