all. My question is at the bottom in bold if you want to get right to it but thought I'd provide photos and details to give perspective on what I'm dealing with.
I had someone on Etsy make me this shelf as per design specifications. It's a plant shelf which will have LED lights hidden along the underside of each shelf. By the way, he lives over 100 miles away and we had this item delivered for a fee so it's not feasible to have him make adjustments. There is supposed to be a gap under each shelf so that I can hide my LED light strip. However, the very top shelf he used two wood boards which resulted in taking up too much space along the underside so that I can hide my light. Here is what the shelf looks like.
Right now it's just sitting on the floor but it's going to be attached to the wall. The highest shelf will be as high as the top of an 86" door opening.
So, my question is:
Can I buy or rent a tool to create a 3/4" deep slot along the underside of my shelf and not cause any damage? And if so can someone tell me specifically what I'd need? I don't need to go completely from side to side. There are nearly two inches left on either side when the light strip is centered along the underside. I know how to drill a small hole to run my wires in the back. I just need assistance on how to make a 3/4" deep slot without damaging my any part of my furniture.
