A Ladder That Levels the Field

At the top, let the board (which is not a step, actually) reach the outside edges of the legs. Drill pilot holes through the board and drive screws down into the ends of the legs. Now return to the other step locations and install the steps as you did the first one.

If you want greater assurance, you can add strength to the ladder by cutting triangular pieces of two-by-four and installing a triangle in both corners under each step. A third method is to cut short lengths of one-inch boards and install these between steps and fasten them with screws or nails to the inside edge of the legs. Be sure the pieces of wood fit snugly.
When the first half of the ladder is completed, build the second one just as you did the first. When the second is completed you can lay the two sections of the ladder on a fairly level surface so that the tops meet and the bottoms are at desirable angles. You can attach the two ladders at the top by using a wide board (I suggest a one-inch board or even a thicker one that is at least 15 inches long and 7.5 or 8 inches wide).
Drill two holes through the wide board and through the top of one of the boards at the top of the ladders. Drill two more near the bottom. Then drill four more holes in the other top board in the same locations. Now insert four-inch-long quarter-inch bolts and use washer and wing nuts to hold the bolts in place.
The two ladders are now connected at the top only. Move down about three feet and install a support or brace from one ladder to the other. Drill a hole through the brace and through the leg of the ladder. Use a quarter-inch bolt and wing nut to hold the brace in place. Do the same with the other side of the ladder.
Now turn the ladder over and repeat the process. I suggest that you use a brace board that is at least three-fourths of an inch thick and about three inches wide. With both brace boards in place, the ladder is very stable.
At this point you need to install the extensions or levelers at the bottom of the ladders. The simple way is to cut ten-inch sections of pine that is one inch thick. Mark off hole locations one inch apart down the center of the sections of wood. Then drill two or three holes (two will work well) in each leg of the ladder. The holes should be between the first step and the end of the ladder. Measure off the hole locations so that they will match up with the holes in the shorter pieces of boards.
Now align holes and use quarter-inch bolts and wing nuts to install the short levelers. Later, when you are using the ladder and you find that one side is lower than the other, simply loosen the wing nuts and slide the levelers down until the end touches the surface where the ladder is standing. Then re-insert the bolts and use the wing nuts to keep the bolts from slipping out.
