until the measurements are the same, retighten the clamps and set it
aside to dry.
Step 7
Now it’s time to attach the top. Earlier we said that when the frame sits
on the planter there should be approximately a 1” overhang all the way
around. The 1” overhang is not critical, just measure the amount of
overhang around the frame and make sure it’s close to the same all the
way around. Once this is set take your combination square to the
distance of overhang plus 3/8” and place small marks all the way
around the frame about every 4”to 5”. These marks are where you need
to drive 6d finish nails through the frame and into the top edge of the
panels.
Step 8
Your planter box needs no finish if you built it out of cedar, redwood,
cypress or pressure treated-wood. All of these woods will weather to an
attractive silver gray after about a year outdoors.
