Step 1: Get a Leg Up
Start by glueing and screwing 2 lengths of 2x6 together, keeping the bottom end flush. They are 28.5" and 23" long, respectively.
Step 3: A Time to Join
Next, cut an 18" piece of 2x6 and glue & screw it between 2 of the legs.
Step 5: Come Together
Now, cut a 24" piece of 2x6, and slap some adhesive on the 'notches' at the top ends of the 2 leg assemblies. Place the 24" 2x6 and screw it in.
Step 7: Sister Marry Me Please
The next thing is to sister up the 4 leg stretchers to beef them up a bit. For this, you will need two 18" and two 13" pieces of 2x6. Glue and screw them in place.
Step 8: Top It Off
The last part of the stand construction is to make the top. Just use whatever 2x material you have, cut them to 24" length and space them evenly. You could make an overhang if you wish, but I preferred the cleaner look of making it flush. Remember to put a space between boards to give rainwater a place to drain.
Step 9: Down the Drain
The next step is to prepare the stand for the barrel's drain. This requires drilling a hole in the top, and another in the side. There will be a 3/4" PVC pipe that exits the barrel, and turns 90 degrees to protrude out of the stand's side.
Step 10: A Solid Foundation
With the drain pipe installed on the barrel, now you must pick a spot for the barrel and prepare the foundation. For me, it was directly under the gutter's downspout. The foundation itself is nothing more than 4 chunks of pressure treated 4x6 wood, placed on level ground.
