Step 1: Materials
-String of choice (I used parachord)
Step 2: Finding the Right Tree
Instead, I recommend walking through the woods trying to find straightest branch or small tree possible that is still alive.
I found a small tree with no branches that I thought was thick enough to withstand the stresses of being used as a bow.
After finding it, I sawed it down for further evaluation.
Step 3: Measure and Cut to Length
While the tape measurer was out and next to the wood, I took the time to mark the center at 25 inches using my knife.
If you do not have a tape measurer, you can use your string to find the center. Place the string over the bow and fold it in half over itself. Measure from one end to find the center and make a marking with a knife.
Step 4: Start Trimming Down One Side of Wood
After the bark is removed, continue removing more of the wood from that same side until the diameter is halved.
For safety, hack away at the wood in a direction away from your body.
Starting 4 inches away from center in each direction will give you an 8 inch handle and will give the bow a stronger point to bend around.
