I got a custom completely adjustable table extension support system, this afternoon from work. I was walking through the fab shop and low and behold 2 channel (unistrut) stands complete with 6 x 6 floor plates sitting there. I was told they've been sitting here for over a year, take 'em. OK! grabed a couple of angle brackets & channel nuts, out to the trunk. All I can think is I may join the 2 stands with some kind of cross meber, or better yet a piece of peg board bolted up! I wish I had a digital camera to share once it's done.
