The holes were done with a 5/8 in. Forstner bit. Can’t take credit for the bevel around the edge - I bought it from Amazon that way. Walnut Hollow Pine Rectangle Plaque, 9 by 12 by 0.63-Inch https://www.amazon.com/dp/B000YQIOH6/ref=cm_sw_r_cp_api_i_5D4SCbPDEXVZG
I have no idea where to post this, and /r/battlestations doesn’t have a daily questions thread sooo... I have an Ikea Linnmon, and I use a two monitor arm/mount on it. Then I saw that there was a dent in my desk from the clamp. Would something like this, putting it between the clamp and desk on both sides, help my desk not break in half?
