I recently moved to my new apartment. As I have a very low budget but a lot of time and ideas, I decided to make my own table. In fact, making this table is not that long if you use these instructions.

I had also other constraints:

I have no car
I have no tools
I want specific dimensions in order to fit my small room
I want to be able to transport this table in case where I moved again

For this project, I reduced as much as possible the number of tools and operations. That is why, even if you need to buy all the tools, the cost is lower than any Ikea table.

Also, you don't need to be very accurate. The parts will works together even if you have two left hands.

Step 1: Tools and Material

Tools:

hand saw
cutter
pencil
sand paper (grit size 80) (optional)
3 clamps (optional)
mitre box (optional)
measuring tape (optional)
square edge (optional)
masking tape (for transportation)
solid plastic bag (for transportation)
cardboard (ground protection)

Material

strap with tightening (5 m x 25 mm)
tabletop (60 x 150 x 1,5 cm)
2 lumbers (300 x 4 x 4 cm)
3 lumbers (300 x 6 x 2 cm)
wood glue (minimum 100g)

Step 2: Preparation for Transport

Cut all the (3 meters) lumbers in half in order to take them in the metro. Use the mitre box and a clamp. Some hardware store have a dedicated space, otherwise do it on a parking place
Make a bundle of wood with the masking tape

You are now ready for (public) transport.

Step 3: Cut the Parts

Using the mitre box and a clamp, cut the 4 x 4 lumber in half again. You should have four legs of 75 cm each
With the same method, cut the 6 x 2 lumber to obtain two parts of 135 cm and two parts of 48 cm
You can make a little chamfer with the sandpaper if the cut is not clean

Step 4: Gluing

Position the four 2 x 6 lumber in a rectangle shape under the tabletop. Let a space for the legs in the corners as shown in the figure
Draw some guidelines under the tabletop. This will help when positioning the 2 x 6 lumber
Put the wood glue under the small (2 cm) face of the 2 x 6 lumbers and spread it with your finger
Position the glued lumber between your guidelines and tighten the clamps
Repeat the last operation for the four table sides

While the glue is drying, you can already start the next step.

Step 5: Shape the Fillet

Draw a line at 6 cm from one end of each legs
Make a saw cut of approximately 1 cm
Draw a nice fillet on the top of the legs
With the cutter, shape the fillet. It is easier if you make a chamfer and then remove the edges by creating new faces and so on until you have a fillet
Make it perfectly smooth with the sandpaper
Repeat that on each leg

You table is done. Let us assemble all together.
