I found an old plank in my shed the other day and got an idea to make a couple of bedside tables with them.

With some loose plans I started cutting out the pieces.

Step 1: Gathering the Pieces

I started by cutting out the pieces after measuring the height of my bed. I decided to make the table in level with the bed, and around 70 centimeters worked fine.

The plank was only long enough for two floors so I had to make an extra floor with a board that I had stored, and to make it a little thicker I put fiberboard underneath and glued the two together.

Step 2: Making of the Cross

I wanted the table to have a cross in the back, so i used two small boards and measured by putting them underneath the two back legs. To make it more accurate I fixed the legs with two planks so they wouldn't move and kept the same distance while I measured.

After I marked the boards I cut them and tried it again. I then marked where the cross-section would be and how deep I had to cut them. After I marked it I started cutting and used a knife for the final touch and to even out the surface in the cut.

Step 3: Fitting the Cross

I wanted this table to be without any screws so I used glue and dowels. I used a dowel kit with a matching drill and markers to make it more accurate.

Step 4: Making the Box

Because I hade to use a fiber board I had to hide the sides of it. To do this I cut the side planks half way in so that they would reach down and cover their respective sides.

I didn't do this in the back because it would get to complicated. I figured the back will stand against the wall anyway. Instead, I had to cut the back plank since it would be slightly lower than the sides who are reaching further down.
In the front I cut out a small wooden pieces, sanded it to make it fit perfectly and glued it in to place.

I forgot to take a photo of the glueing moment, but I used clamps to get it nice and tight.

Step 5: The Assembly

So, it's finally time to see if it all fits together.

Again, I used dowels to avoid screw head sticking out. Dowels and glue is more than enough to make it stable.

Step 6: Painting

Now it is time to paint the pieces. I picked the pieces apart again and painted them one by one.

It's important here to organize them so you know what pieces goes in to which hole since the dowel needs to fit. Otherwise the legs won't be exactly where you want them to be unless you were super accurate when drilling the holes for the dowels and put them all in the same place.

Step 7: Final Assembly

Now it's just to assemble all the pieces again with some glue. Make sure that the paint is completely dry to prevent to brown planks to get white stain.

Good luck!
