TV trolley with drawers made by S Rees, 2001

Air Hockey Table made by C Van Voskuilen, 2001

The table is made from an 8'x4' sheet of Medium Density Fibreboard (MDF) and has Pacific Maple around the edge of the playing surface. Legs are 70x70mm pine attached with bolts to 1.2mm steel plate brackets. A requirement of the table was to have removable legs for storage. The table has two support braces inside the air cavity to keep the playing surface from sagging.

The holes drilled for floating the puck are 1/16" diameter, and there are 3360 of them at 25mm spacing, all individually drilled!

The air pressure was achieved by using this adapted blower from an evaporative air conditioner, found on the side of the road following an annual Council Cleanup. The blower is removable, by simply sliding it out from the mounts seen here. The 3-speed switch and wiring were also used, with the motor able to be disconnected from the switch by the use of a multi-pin connector from a wrecked car. A suitable high volume fan from an air conditioning supplier would have cost over $240, but this one works very well even on low speed, with a $zero price tag!

This end view of the table shows the galvanised iron goal and catcher chute. The goals were tailor made by Mr Wilson. It was found that with a fast goal shot that the puck would often bounce straight back out of the goal so another piece of galv iron was spot welded at an angle, to the inside of the goal back, to deflect the puck downward. A few different materials were tested for suitability for the puck, the fastest being a thin clear perspex that was hard to see. A slightly slower and much more visible material was white polystyrene sheet. A couple of different plastics of varying weights were tested, but they proved too heavy. We also made a puck from 12mm thick radiata pine which worked well, but was a little slow for the more experienced players. To add variety and interest to the game we produced a triangular, and a hexagonal puck.
