Step 1: Make you wooden raindrop (or teardrop) shape
B. Sketch out raindrop your shape around the hole and cut it with a scroll saw.
C. Finalize your shape and finish with a belt or disc sander.
D. Drill your pilot holes in the face for you to attach the acrylic later. I did this so I wouldn't crack the wood when setting the screws.
Step 2: Make your acrylic plexiglass face
B. Practice cutting your countersink into plexiglass scraps. You will want the screws to sit beneath the surface.
C. Pre-drill your holes so they are exactly align with you pilot holes on your wooden shape. My drill press has a laser alignment on it so this was pretty easy for me. There are other ways to do this if you don't, such a paper template.
D. Countersink you acrylic shape.
