But it has to glide on something that provides just the right amount of stiction, that's where the laminates or powder coated aluminium comes in.

alternately you could get a 600x600 sheet of teflon and small laminate pads but you wouldn't be able to afford food for a few weeks.......

Here is my solution:
600x600x3mm aluminium plate powdercoated in Aztec Gold and the ground board with 4mm thick PTFE pads at 45º to the direction of movement, edges of pads are bevelled to glide over any imperfections in the powder coating. Pivot bolt with brass bushing and PTFE pad under the middle to reduce the perimeter load, this pad is shimmed 0.6mm with aluminium shim.

Smooth as silk
