The Process: Draw up a plan for custom size planter boxes and execute the plan.
Let’s start with a plan sketch… and then get busy cutting the outside corner posts.
Next, I cut all the other parts, making the best use of materials.
Be careful when cutting on the table saw. Knots can break loose and jam the saw blade. When you are running lumber through your saw and all of a sudden the saw does not sound right, safely stop what you are doing, unplug the saw and proceed to check for problems.
Everything stacked and cut, ready for assembly.
