DIY Air Hockey Table

Step 2 Building frame

A: In order to build the framework you need to have a proper tenon saw. The 8 different pieces all need a 45-degree-angle end. Extreme accuracy is required to make the corners fit into each other. We didn't want this project end in a complete disaster, so let a lumberyard do this for us ($18 extra). If you do have the right tools, you should just make sure you saw them to the right measurements.

B: If you've got your beams (no. 1, 2, 3 and 4) ready, lay the chipboard onto the floor. Then check whether all sizes are correct by putting the beams down to their positions on or against the chipboard. It is important that the floor you're working on is flat.

C: By using some nails and construction (polyurethane) glue, attach the four smaller beams (no. 3 and 4) to the corresponding bigger ones (no. 1 and 2). The smaller beams should be glued at the right height. So the chipboard fits into the ridge.

D: Glue the four sides together, wrap a strap around the framework and tighten it. The chipboard should still be in the center of the construction. Leave the glue to harden for at least 4 hours.

E: Predrill all four corners and screw screws in them (see the image below)
