Live Edge Cedar Mantel

After recently moving, well a couple years ago now, my wife and I were thrilled to have a fireplace. The large stone fireplace was lacking a mantel, and we debated on whether we should add one or not. After coming across a beautiful piece of cedar, I decided that it would make the perfect mantel for our fireplace.

The piece of cedar I had was originally about 8 feet long, 3-1/2” thick, and 15” wide with two live edges. My first step of the process was to rip one of the live edges off. Given the thickness and weight of the board, I ended up ripping it with a circular saw in two passes – one from each face. The next step was to strip off the loose bark from other live edge. After that, the challenging part began…

Since the mantel was to be mounted against the stone, a straight edge would have left some very large gaps between the mantel and stone work. In order to get a better fit I needed to scribe it, and since the mantel was so thick, I had to scribe both the top and bottom faces. I ended up using a compass to scribe the stone onto some scrap 1/4” hardboard I had laying around. Also, since I was going to scribe both faces, I ended up hollowing out a large portion of the edge of the mantel so I could cut each face along my template (it was also nice to remove some weight). After cutting the templates, test fitting, and making adjustments, I traced the templates on the each side of the mantel piece and cut it. The fit was not perfect, but it was actually better than I thought it was going to be. Most parts rest directly against the stone and the biggest gap is probably about 1/4”.

Once the mantel was cut to size and scribed, I sanded and finished it with a few coats of poly. I attached the mantel to the stone with 1/2” threaded rods. The rods go about 2/3 of the way through the mantel and about 6” into the wall. I did not end up not cementing the rods in place as the weight of the mantel and fit of the rods was enough to keep in securely in place.

For what seemed like it was going to be a very simple project (only one board, no joinery, etc.), it was actually very time-consuming and tedious. I was also a little on the fence about having a mantel for the fireplace to begin with, but I am glad I put it up now.

Great job, looks really nice. We’re our own worst critics.

This looks awesome! Any chance you can explain how you secured the mantel to the wall/stone? When you say 1/2” threaded rods, does that mean drilled holes into the back side of the mantel and pounded in rods? How did you then get it to stick to the stone? Did you drill holes into the stone, etc? I’ve never screwed anything to a wall except for wood and drywall.. thanks!

I drilled holes into through the stone and into the studs behind the stone (probably about 6” deep in total from the face of the stone to the back). I also drilled holes into the mantel that went in about 2/3 of the depth. From there the threaded rod actually is just pushed into both the stone and the mantel by hand. It is not screwed in. The weight of the mantel and the tension from the alignment makes it pretty secure without any adhesive too. I also like this because I am able to take it off if I need to.

Ahh, gotcha. That sounds like a great method, thanks for sharing ;)
