Rather than hijack another thread posted recently I thought I'd keep this separate. I made this earlier this year but just recently got pictures. There is another top design I did and wanted to show but I'm waiting for the owner to take a picture and send it to me. I'll add it if he ever sends it.
The tubing is 1" x 2" x .12" so it's not a lightweight. The legs are 1-1/4" and 1" pipe. For height adjustment I didn't want to depend on pipe wall thickness for threads so I welded a T-Nut to the outer leg. I milled down about .03" to create a flat spot for the T-Nut to rest on. This made setup a lot easier for welding it.
The top is 2 pieces of 3/4" hardwood ply with oak veneer. Not exactly 3/4" but close and I used hardwood (which I think is really a soft hardwood like poplar but not sure) because it seemed harder than the softwood version and you get a nice looking top. I welded a 3/4" bolt to a 4" x 4" x 10ga (I think) piece of steel and sandwiched that in between the 2 pieces of ply. I routed out the underside of the top piece to clear the metal so that would allow the full thickness of the bottom piece for strength. I added some epoxy in that area to fill voids (I'm anal, I know) then used Titebond, clamps and screws to hold the 2 pieces of ply together while it dried. I welded 1/2" bolts with rollers on the frame to allow the top to turn easily. I got the "nut" from McMaster. It's a simple matter of reaching under the table and give the "nut" about a half turn to loosen or lock it up.
My chair has been a fold-up captain, 5 gal bucket or cooler. With the chair in one place you can rotate the table some amount (probably depends on the individual) and still be comfortable. Since it is the frame that is leveled, you don't have to re-level when rotating the top.
I usually drive to a spot and plant myself for most of the day so I don't have to move it that often. The angle of the legs is 22 deg. More than most but I think this thing is really stable because of it. As you can tell the top rotates 360 deg.
I swear I had my CoolPix set to macro but the ground is in focus instead of the T-Nut!
