Step 1: Arrow of light template
Next I Traced the stencil I made onto a piece of MDF. I then used a scroll saw to cut out the stencil. Finally I sanded out any chatter marks within the template.
Step 2: Routing the arrow of light
Clamp the template to the wood your using. I’m using pine. With the router set at the depth you want, run the router though the template. Make sure the router is completely stopped before you lift it to see your work. Otherwise you risk damaging the template. To make things easier I used a vacuum to pick up the saw dust.
Lastly, use a round over bit to ease the edges. Don't forget your safety gear.
