DIY Air Hockey Table

Step 4 Attaching pillars to surface

I: Saw about 150 to 200 wooden pillars with a height of 35mm. We've tested whether the supports were strong enough (no glue was involved yet). If you can stand on the surface without breaking it, you should be on the right track : )

J: We placed the pillars 3 'squares' (75mm or 3 inch) away from the edges and 4 squares separated from each other. Amount of supports used: 9x19-2=169. But you can experiment with this pattern yourself. In the middle we left out 2 supports to make sure that the air inlet would fit in. Edit: Air inlet fits in without removing any pillars, and air inlet will be made in a corner of the table.

K: With NON-polyurethane glue (regular white wood glue) fix the supportive pillars to the non-smoothened side of the MDF. If you would use polyurethane glue the pieces of wood would be slightly lifted or displaced. Put the chipboard onto the pillars to ensure that the pillars stay in the right place while the glue is hardening.
