I used 6 chains about 12"s in length, 6 square peices of 1/4 plate that were about 2"x2" with a 1" hole in the center, and a triangle that is 8"x6"x6" with a 1" hole drilled in the corner.
Weld chains to triangle on side that is opposing the corner with the hole. one in each corner and one in the center between the other two.
then weld three of the square 2"x2" peices to the other ends of the chains so they are welded at the corner
make sure that the 2"x2" squares sit at the same plan as the triangle.
then weld a chain on the opposing corner of each of the 2"x2" squares
then weld the other three 2"x2" squares at the end of those chains
make sure that when you cut all the chains you have both ends of each length of chain facing the same way that way when you weld them to the steel all the flat parts will be on the same plan. I did not do this and had to cut everything twice. I notched both ends of the chains so that the flat steel slide into the link and could be welded on both sides.
I bought a set of 6 stacks that were 24"x3/4" off of ebay and ran them through the holes in the 2"x2" squares at an angle into the ground and then hooked my winch to a clevis shakle through the hole in the triangle
This anchor has worked very well at getting me unstuck and to hold my jeep in place when i was pulling out a dodge ram.
I have not tryed it in sand only in mud and dirt. I don't think it will do very well in sand.
