This house was built in the mid 1950s. I assume the rock wall was built at the same time. It has an old railing that is not attached anymore and needs to be replaced. My current plan is to cut off the old railing and build a wooden post and cable railing.
This is just an example of what I'm trying to accomplish.
My issue is that I'm not sure how to anchor the posts to the wall.
The current railing is secured via some odd pieces of rebar and having some of the metal posts mortared in to the wall. The rebar has detached in some places and some of the posts have just broken off, leaving the whole thing just flopping around.
My original plan was to cut the old railing off and get something like these post bases and anchor them directly to the wall using these bolt wedge anchors with some washers or something to shim it to keep the whole thing level. I've since realized that bolt wedge anchors are probably not a good idea on these stones. I'm also worried that using a hammer drill on this wall will simply knock the rocks loose.
I think I've got a handle on how to build out the railing if I can figure out how to mount the posts to the wall. That's my concern right now. Thanks.
