To make the base of the OB-Pod I have used a bamboo chopping board (just like my copy stand
). I have a penchant for using laminated bamboo; it is fairly light, strong, doesn't warp and bamboo is the fastest growing hardwood. An excellent alternative to cutting down old growth forests. I hope you can get laminated bamboo chopping board or bamboo flooring panel in your neck of the (precious) woods.
The board size is not critical but you should use something big enough to provide stability to your camera without being cumbersome. The material should be light, strong and resistant to warping and swelling.
Some of the parts are probably regional but I have included photographs so you can find substitutes or even just understand the local terminology.
The only really critical issue is that the dome nuts and furniture feet work together. I used a brand called "The Original Slipstick Gripper" but you don't have to use furniture feet many other components could be used. One untried possibility is to drill shallow over sized holes in the board and glue washers over the holes (see diagram), this should still allow the precise alignment required but I have not tested this idea.
What ever you use for the moveable holes, they must be made from a good strong hard
material with a suitable sized clean edged hole
that will support a dome nut. The hole should be ~70% of the diameter of the dome nut.The dome must be supported by the edge of the hole (see the cross section diagram).The reason I didn't just drill holes in the board is so I can move the holes around while gluing to make them perfectly aligned with the 3 dome nuts after they are position locked in the "T mount". This is critical unless the holes are precisely placed the mount can jump between 2 or 3 different stable positions.
