For carrying them around so you don’t bend them. I used the smaller piece of walnut that came with the glowforge. To my surprise, it was solid, not ply. Which worked out awesome because I decided to sand the edges smooth. Then I rubbed Teak oil on the edge. Its 4 layers. The front and back are exactly the same. The 2 layers in between are U shaped.
I got a little carried away on one corner… lol. But I used a small drum sander, not a belt sander. Should have used the belt sander. Oh well… it’s for me.
Reminds me of an phone case I got years ago that was laser etched (2 pcs that slide together, since you can’t flex the case to fit like other materials ). But also no longer have that phone…
And at one time (with this old phone) I did order a case from the company that makes my business cards to have my phone look like a giant business card–so maybe your next project–wood phone case “business card”!
I use loctite professional superglue. Bonds in 10 seconds. Then just buzz the edges with a belt sander (which I should have used instead of a drum sander). I gave myself 0.03" extra in the width inside. If you give yourself enough thickness on the rim, you shouldn’t have a problem.
