First: The small fence posts, come pre -treated and only 1.97 each. I bought 4 of them. At 45" each, I cut twice at 15 inch intervals gave me 12 pieces. phew, sorry if this feels like math...
Next stop the wheel isle, just ask the guy in the orange apron. 4 swivels should do it. They were only 2.99 each. I nail gunned 2 pieces to 2 pieces that formed a square, then filled in, every 1.5 inches the other four, Then 2 to more underneath for the wheel base. I know, just look at the photos, explaining it it much harder then the doing
Now Screwing the wheels, power screwdriver is preferable, and since I like me a good shortcut, I only used 2 screws for each wheel, on opposite corners...seems solid
Ta -Dah. The motivation was, my new Meyer lemon tree. I can now roll it to the house if there is a threat of frost.
Next post will be my epic painting day...
