Thanks for the tip. This was my first instructable and I wasn't sure how detailed I should get. Since the system really is about the supports, I left the details about my specific top a little vague.
3 inch solid oak sounds pretty heavy. I made my top look heavy by using the skirts around the sides, but tried to keep it as light as possible. My example will hold a tv, although it does flex a bit. The counter sink idea sounds interesting to hide the support and will also stabilize it. The down side is that you wouldn't be able to re-position the legs if you wanted to.Some other commenters have suggested alternative materials that could beef it up, like black 1" water pipe (imrobber). It's a cheap enough project that you can experiment. Thanks for the feedback.
Thanks so much. Unfortunately, I didn't make the finals of the table contest, but we'll see about the others I entered.The cutting and welding required for this is minimal and should be only about 20 min work for even the most inexperienced welder. Maybe a makerspace interest group or local community college could help you out.
Sounds like a feasible option to me. That might even make the spacing between the supports more adjustable. I was going for a clean-industrial look, but the pipe may give it a cool steampunk vibe... and would probably make it more rigid as well.

I don't think the weight of the top will affect the stability as much as the rigidity and angle of the legs. When building the prototype, I used a 2x4 as a top.
Sounds like a cool mod. I would like to see how it turns out.
The prototype I built does flex, but I think a few small tweaks would really help stiffen it up. Originally, I was going to use square stock for the vertical support for that reason. A small diagonal support at the support arm and foot would also help. Good luck and let me know how it goes.
