For the floor piece, I know what Joel did: he bought a piece of wood from a craft store, glued a piece of non-skid rubber stuff to the bottom (or was it sandpaper? I can’t remember…), then screwed the bottom flange for the pole into the top of it. I don’t believe it was screwed into the floor at all.

He also has exposed beams in the basement where he put up his pole. The top of the pole is attached to the side of one of the beams with brackets. He had to reinforce the beams a bit, just in case. The only drawback of his way of doing it is part of the fixture for the bottom part of the pole has exposed screw heads; they stick out a good quarter to half an inch. He had to wrap it up good with electrical tape and some foam.

Here’s some links to his videos:

This is when he went to buy the parts when he changed to a larger diameter pole, dunno how much of this is repeated information or not: http://www.youtube.com/watch?v=JS3_1Eusd34&feature=channel_page
