Step 1: Supplies
Four-14 inch 4 by 4's
Two-41.5 inch 2 by 6's
One-48.5 inch 2 by 6
Two-31.75 inch 2 by 4's
One-39.25 inch 2 by 4
Two-46 & 1/8 inch 2 by 4's
A piece of carpet 36 by 40 inch or a dog bed
Tools needed: (the tools pictured above are what I originally planned to use but then used many more)
Various size screws
A circular saw
First pry off the top and bottom support board on the bottom. Then measure 4 inches in on the cross support and cut that off, do this to each corner.
Next draw a 4 inch by 4 inch square, do this to each corner and cut. Then use the chisel and clean out the corners.
Now measure 6 inches in and draw a line across all the 14 inch 4 by 4's. Line up the 6 inch line so that it lines up with the bottom support. Then put a 3 inch screw in diagonally to hold the 4 by 4 in place. Do this to each corner.
Next put the 46 & 1/8 inch 2 by 4 through the bottom. Then put the cross support you pried off in the beginning on and use 2 2 inch screws on each side. You then need 10 more 2 inch screws. Put 2 in each cross support in to the board you put through and put to into the 4 by 4. Then do this to the other side.
Now take the two 31.75 inch 2 by 4s and put them in between the shorter sides and put a 2 inch screw in sideways at each end. Then take the 39.25 inch board and put that in between the 4 by 4s on the back. Now put a 2 inch screw in sideways at each end.
Now you just have to put on the top boards. You are going to need the 48.5 inch board and the two 41.5 inch boards, the 2 by 6's. Now cut a 45 degree angle off on each side of the 48.5 inch board. Then cut a 45 degree angle of one side of each of the 41.5. Next position them on top and put 2, 2 inch screws in each board.
Then you are done, you can now add carpet or a dog bed!
