Have a large rock fireplace. I want a mantle...

straight across or a surround but my husband is not interested in the project. Any extremely easy/simple way to add a mantle? There are bookcases on each side of the fireplace; 100" between bookcases which are 8" deep.

    to give suggestions it be easier to see how your rock fireplace looks where your wanting to add a mantle? Is there a flat surface on the top? By code you also need 36” from the top of your fire box to and combustible material like a mantle that you be adding To pass code! Use to be different measurements in the old days, 6” on the side and now it 12” and top use to be 18” and now is 36” in moultnomah county! Other counties may have different regulations? But I advise checking your laws requiring combustible materials next to fire place for their code requirements. Otherwise if you ever have your house catch on fire and you didn’t get your permit and have everything to code. Your home owners insurance can refuse to pay for any damage you have? Legallay, it’s not as simple as just adding a mantle to your rock fireplace! You’ll need a permit and have it inspected to be legal and be covered under your home owners policy! Sorry to be the bearer of bad news, but rather you know now then after you have a fire in your house that your insurance won’t cover!

    Will depend on how flush the stone is, if you stones jutting out they would have to be scribed to fit around the stones. But if they are smooth enough, you would get a carbide or diamond masonry bit for a hammer drill and put in a series of threaded bolts in the stone leveled and secured with 2-part epoxy .... check this on 1:46 https://www.youtube.com/watch?v=ZBQFvb-5xVo&t=38s once you have dry-fitted the beam on the bolts, level and its good to go, you mix 2 part epoxy into the holes in the mantel and put in place.
    If your going to make a faux beam here is one where the guy scribed it to fit over uneven rock fireplace.... https://www.youtube.com/watch?v=mbmILA-JqNk&t=6s here I would make and add a wooden cleat across the fireplace to fasten the faux beam to it. https://www.youtube.com/watch?v=JniIduCrkvE

    The information from Gale and Sharon would get you started on the project, especially Gale's. As with all projects a little forethought goes a long ways to a proper finish. The one suggestion I have is that you add electrical outlets, on top, at both ends. If you plan on anything on top like Christmas lights or anything electric, having the outlets right there saves a lot clutter. It also keeps nice dangling wires from mischief makers (cats, dogs, small children or even large beings :-) ). The lead to the mantle can be run in multiple ways, but the big thing here is that it does not have to show, is usable all year round and gives you the options.
