I just built a table using these plans as a model. I had to make some changes because the wood screws suggested for holding the flanges to the table bottom is a POOR idea. No way a couple of wood screws are gonna hold up for the long term, it's a bad idea.
Instead, I drilled all the way thru and used carriage bolts for a MUCH stronger hold. Also, the wedges are pretty difficult to cut by hand and they came out rough. I ended up using Bondo as a skim coat to smooth the cut side of the wedges for a perfectly flat surface. If I were to do it again, I'd make the wedges a little thicker to increase the angle a bit. A good table saw and a jig would make this job easier.
I used one sheet of 3/4" wood, and the table is pretty steady, but it does flex a little under pressure. Using two layers of plywood would make this table indestructable. Also, you might want to cut an oval hole in the side of the table for a carry handle. It's heavy.
You may want to play around with the location of the table legs before you do anything permanent. Maybe clamp them on first and try it out for balance. I got mine close, but I wish one of the legs was moved over a few inches for better ballance on the front end of the table. It's "good" enough so I'll leave it alone.
Other than that, it's a good solid table. I spent about $85 on materials.
$20 - Wood for table top, wedges
$25 - Floor flanges, end caps, hardware
$18 - Pipe cut and threaded at Home Depot
$7 - Primer quart, tinted to match paint
$8 - Paint
$3 - Sand paper
$5 - Rustolium aerosal for legs.
I originally used folding table legs, but the table was not steady at all, there was always a wobble going on. I took them off. The tripod legs work much better and are 1000 times stronger. Good luck!
