Completed a second tree ring as shown. Thought I would share that with the community as well.
Why make "tree rings"? you ask. As part of a landscape, a tree is a very special plant and to give it a more formal air and enhance it's place in the garden, a tree ring adds that touch of formality and "class" to the scene. In addition, with this method, I am able to "label" the ring, or add personal touches and or tree names. It's a fun project and I plan on making at least a few more for other trees I have or will obtain.
To make the ring, we need a form in which to pour the concrete. I decided a three foot or 36" ring would be adequate for my small trees so started by making a 36" circle out of cardboard.
Step 2: Use Template To Make Pattern For Forms
The circle is divided into 6 equal parts so that there will be 6 blocks or pieces of concrete surrounding the tree. Consult any geometry book or go on line and look up how to dissect the circle into 6 equal or almost equal parts. The pattern is one of these 6 equal sections. This can be traced, or when laying out the circle, use your circle drawing tools to mark a separate piece of cardboard. I wanted to make the segments 4.5 inches wide, so simply drew an inner circle 4.5 inches shorter than the large template.
Step 3: Cut Pattern And Use To Mark Wood
The pattern is then placed on a piece of 2 x 8" lumber, centered between the edges and the pattern to cut is marked. Leave several inches on each end so that the ends when cut off can be used as end caps for the concrete form.
Step 4: Cut Form Out With Bandsaw
The first step here is to cut the angle of both ends. I use the cut off miter saw for this step. The form is now cut on the band saw as shown.
Step 5: Make A Base For Form
What we end up with is the basic form of 4 pieces of wood that will have a base, or bottom, attached with drywall screws.
