Sawing the Form Base
I use the fine miter saw to make the first cut two inches in from the end of the board. Part way through these cuts you can stop and turn the board over to see how you’re doing. And to make some adjustments as you go.
I’ll start the other cut with my miter saw it has a stiffer blade and it’s easier to get off to a good start with.
The 36 inch panel I believe is the most versatile size for a garden bed but, you can make the panel’s any length you like. The concrete raised garden beds can be any size you want.
With the larger handsaw I finished the cut to remove this corner.
I checked these cuts with my square. And they looked okay.
Checking for Square
Next, I’ll measure 36 inches from the end and mark around the board with pen and square.
I marked this side of the board as the “bottom” then cut the board along this line. Then mark the cutout on the opposite corner.
And as before, make these two cuts. I checked these cuts with the square and use some medium grit sandpaper, wrapped around a block of wood, to fix any cuts that were not so straight or square. Don’t over worry much, just try to follow your lines as best you can.
Make the SIDES – Form for concrete raised garden beds
Now that we have the base done we’re gonna cut the sidewalls from an 8-foot one by four, and here’s what we need to do that.
A miter box and a miter saw, a drill, and if you have one a driver (but a drill is probably all you need), Phillips screwdriver, three drill bits: 1/2″, 3/16″, 1/8″, some wood glue, and a bit of medium to coarse sandpaper. Two sizes of screws: drywall screws: #6 1-5/8″ and a #7 1-1/2″ pocket, or cabinet screws, flathead. And we’re going to use a tape measure, a square, a drill block, a pen or pencil, and a scrap piece of wood.
From the concrete raised garden beds plans we’re gonna make all the cuts for the side walls and for the end assembly pieces. We’ll need two of each. What I want to do is with my miter saw screwed to the workbench, I’ll check the end of this 1 x 4 to see if it is square.
If it’s square then I can use that end.
I’ll mark the first cuts. Both the side walls are 35 1/2″ and I’m going to mark and cut one at a time.
This particular miter box has these little pegs here to help hold the workpiece while I’m cutting. Which is kind of handy. I know it’s a little bit of a flimsy box but for this type of project it’ll do just fine.
I marked my line 35-1/2″ and I want to cut on the right side of that line. And then what I’ve been doing just a little bit of a little sandpaper you have that on a sanding block that works for you.
That’s the first and then we’ll take another 35-1/2″ and then we’ll have our side walls for our first form.
