You will need.
1 - 8ft 1/4 in. Piece of a wood of your choice (preferably something dried to prevent warping)
2 - Dual threaded bolt thingy (pictured below)
2 - wing nuts
2 - Washers
1 - Bolt (universal camera mount size)
Scrap metal is optional
-Table saw / hand saw.
-Portable or stationary jigsaw.
-Small nail gun
First were going to cut up that beautiful piece of wood you selected. The table i wanted to place this on was about 30 inches across and i wanted it to barely fit so after accounting for the feet i made it 25 inches. This is also a nice size if you want to use it on a larger table. Boom! top size selected. Now the legs are 20 inches because at max height (about 19.2 inches) the feet are just out of view. The small pegs are for support which it needs unless you sink the legs into the feet. Sinking the legs into the feet would be way better, look nicer and take more time and tools to do properly. Much to my fathers dismay (He's the master craftsman that could do this with his eyes closed and still make it showroom quality) i won't be doing that on this project for my own reasons.
The foot size however i believe was random.
So you're going to cut with the saw you selected.
-1 piece of wood 25 inches long
-2 pieces of wood 20 inches long
-2 pieces of wood 7 inches long
-4 pieces of wood 3/4ths of an inch long
First were going to draw some guide lines on the legs. You should find the center of the board by measuring its width and dividing it by 2, then we're going to mark off a segment we can cut out. It should be just slightly wider than your dual threaded bolt. grab the legs and drill a hole in each (within the guidelines), the size of the hole does not matter as long as you can fit the blade of a jigsaw inside of it. Then we cut that segment out and sand the edges so machining threads on the dual threaded bolt slide up and down easily inside it.
Here were going to find the center of the two feet and attach the legs. So far the legs should have a slit cut into them The bottom is the end that has more space between the end of the board and the slit. were going to find where it sits in the center of the foot and mark it with a pencil. Then apply a little bit of wood glue to the bottom of the leg, you can smooth it over with your finger you don't wan't too much on there just enough to cover the whole surface and not have too much come out of the sides when you press it down. press it firmly into the designated area of the foot. This next part is optional some people would clamp it as is and wait for it to dry, But i chose to nail it, to nail it you need to hold it upside down and put 2-3 small nails in the bottom of the foot making sure they go right under the leg. If you didn't put too much glue the foot should stay in place without too much effort. Now do the same thing for the 4 small pieces of wood you'll be glueing 2 sides (the sides touching the leg and foot), These are just for a bit of support.
now test it. try to attach the camera and if it holds tight, just assemble and you're done =]
if not...... and the bolt is too long try adding a washer to the bolt BEFORE you put it through the top board. that way you are not holding the camera away from the board and it can clamp well and you are less likely to lose the washer.
now we just assemble the stand, to assemble put the two bolts from the top piece into the slots in the legs, add washers and the wing nuts and you are ready to rock and roll =]
