The plaque is composed of three layers held together with Chicago screws (Amazon link) because I’m terrible at using glue neatly. I keep several different lengths of Chicago screws to match the total thickness of the layers I use in a project.
Here the engraved middle section is 1/16" maple hardwood and the proud frame is 1/16" walnut hardwood. Both are from Ocooch Hardwoods, which sell 12"x24" pieces in some woods. I applied medium tack transfer tape to the wood with mixed results for the engraving. Some engraving caused the tape to lift, which didn’t effect the engraving but did cause some scorch marks. The Mr. Clean MagicEraser removed all of the marks easily!
The back layer is 1/8" Proofgrade Draft Board for stiffness.
Here is a PNG of the composed layers showing the how the screw holes align exactly:
and here is a test print I did to judge laser settings (speed/power) for the engrave on the maple hardwood (with transfer tape removed):
I stopped the print when I realized that speeds faster than 300 were going to be too light.
The lettering for the engrave is probably of less interest here. It’s done in Adobe Illustrator from a commercial font called Brilon and makes use of alternative glyphs, including compound letter combinations (CH, DO, RO).
