I have a sandstone fireplace, and the blocks poke out about 1.5" beyond the grout. Years ago I mounted a 15# deer head up there - I put a 3" long, 1/4" expanding bolt (lag) in the grout. I drilled in about 1.5", put the bolt in, tightened things up, and it worked fine. I needed the bolt to stick 1.5" out of the grout in order to accommodate the stone blocks.
This month I picked up a caribou mount from the taxidermist. It weighs 35# and (once mounted) will extend out 40" from the fireplace. A lot bigger than my deer....
I want to use the same hole I had for the deer. I opened the hole up and tried to mount it with a 3/8" expanding bolt (just like the one I had for the deer but a little bigger). No dice - once I got it up there, I put a little pressure on the mount and the bolt slid right out.
I was thinking of drilling bigger and deeper into the grout. When the 3/8" bolt popped out, some concrete came with it, so now I'll have to move up to 1/2" anyway. Perhaps if I go 2.5" into the concrete, and put a screw shield in there?
I'd appreciate any tips. :bash:
Thanks a lot,

Well I guess I would take you same bolt and put it in with a high grade epoxy glue.
Let it cure and see hom that works.
:yeah:
Or fill existing hole and start over. I would make sure my mounting bolt goes more than 1 1/2 inches in though. There is a blue colored concrete screw the threads into a hole that is slightly smaller, not sure if they have one over 3 inches though.

Hey Mike, if you have a stone face fireplace. Most likely there's O.S.B or plywood behind the stone. Go to a hardware store and get the biggest expanding wing type dry wall anchor they have. The big ones have a bolt with them. If the bolt isn't long enough get one that is. I've hung a ton of under cabinet microwaves with these.
It would be nice to see a photo and know if this is stone fascia onto plywood, OSB or GWB, or is it in an older house and stone over CMU.
My fireplace is gas and enclosed. Curious if a real fireplace esp a wood burning one would soot up the mount... :dunno:
A masonry fireplace should have a liner well inside of the brick facing, probably with a CMU structure holding the whole kit and caboodle up. It you are getting soot thru any penetration on the veneer, that is indicative of a serious problem with the liner and should be addressed immediately. There are several ways to do it, and it most likely can be done from above with limited impact to the existing chimney and wallet.

one of the worst things for a mount is heat

How much heat are you talking about? My elk from last year is in a room with a west facing window that gets a lot of afternoon sun and the elk is close to it. The blinds are always closed, but I can't help but wonder if its subtly cooking a bit sitting there.
