I just did this for a client in Bend OR - not live edge, but 8¡± thick with returns at the end in white rift-sawn Oak. ?We had a local fabricator make steel L-brackets that attached to the studs - 3 of them held together with flat bar in two places. ?The vertical members were 3/16" wall 1.5 x 1.5 square tube, mitered and projecting out from the wall. ?The verticals were drilled and through-bolted with carriage bolts to the studs about 2 feet long running upward from the CL of the mantle. ?This mantle projected 12¡± from the wall, and the L-brackets projected 10¡± total beyond the sheetrock. ?The GC used 2¡± augers to bore out for the L-brackets, and imbedded the entire mess in epoxy. ?It¡¯s never coming down.

So a friend wants a live edge mantle from an Ash log. He already has the log cut on the band mill. It is 11¡± deep (sticking out from wall) and 7.5¡± tall (vertical). The mantle will be 5¡¯ long.
I can run the 11¡± wide top on the jointer and then make the back 90 deg to it. Finally run it thru planer to get the bottom parallel to the top.
I need to return each end of the mantle so will need to cut 45s. I plan to do each 45 deg cut in two passes (due to 7¡±+ thickness) with material on one side of the xcut fence and then flipped and placed on the other side of the xcut fence. I have not done this so far.
Finally i can plough a recess on the back side on all 3 pieces for mounting purpose and process a piece of wood that fits perfectly in the recess. With this piece mounted on the wall the mantle can be pushed on it and screwed from bottom. I can easily plough about 3¡± deep. Is that deep enough for a 11¡± deep mantle?
I know there are many mounting options out there but would like to find out if what i described would work?
