The nice thing about the 3 leg table is it is self-leveling, a problem that 4 leg tables don't deal with well. I looked at all kinds of folding leg systems and never saw one that looked as stabile as this one. I just went out and priced the pipe and flanges, pipe was less than $20 for 3-30" pieces cut and threaded, and the flanges are $4 each. A 6' piece 1x6 oak is $16, didn't check on a cut piece, but I think I may end up building 2 tables anyway. Looks like a good winter project!
