We found this piece at a yard sale or a second hand store, normally we'd use individual pots in it, but due to its narrow size, arranging the pots was sometimes awkward depending what flowers we chose for it. So I decided to make a custom sized planter that would fit its inside dimensions.
Step 1: Preparation
I drew up a plan of what the initial layout would have to look like and to figure out what size piece of aluminum I would need. It turned out that I would need a 30" by 16.5" piece.
Step 2: Tools Used and Material
I used tin snips (not Pictured)
2 or 3 Sharpies
portable work table
Sheet metal edge folding pliers
A short piece of 2 by 4
1 pipe clamp (bar clamp)
A large piece of scrap aluminum that was from old steam pipe insulation covering
Step 3: Layout and Start Cutting
I laid out the folds and cuts to to be made on the piece of aluminum.
Step 4: Construction
I clamped the aluminum to the table and folded the front and back edges of the planter over on itself. the fold was 1/2" wide and makes for a nice edge on the planter.
The ends were then folded up, then the front and back were folded up.
Step 5: Construction Finishing Up
With all four sides folded up, the end piece has a small flap that folds over the inside end pieces.
Four drain holes were then put in the bottom using a screwdriver and a hammer.
Step 6: Installed !
A couple of pictures of it finished.
A before and after picture of it installed.
My wife loves it.
