Most likely wood isn’t offered as a base, because most wood is too light and does not give the weight one needs to have the rig adhere to the desk or table without moving around. I had a wooden base at first, but quickly discovered I didn’t like it. I now have a granite base and it rocks.
Some folks have gone to their local counter top makers and/or funeral monument makers and have made bases out of scraps they bought or were given. A weight of 7 pounds or more with sticky rubber feet should do it!
