Folks ask: “Can I mortar logs for a stairway into a cordwood wall.” The answer is YES, if you do it using Best Practices. If not done correctly, the stairs will loosen in the cordwood wall and cause degradation of the mortar.
Above is an example of a cordwood stairway using heavy timbers for EACH and every stair tread. The stairs themselves are approximately 12″ x 6″ and they are stabilized on each tread using vertical posts of the same dimension.
The sign says “Wipe Yer Paws!” You will notice that the stair treads on the outside are still firmly attached to the mortar after decades of use.
Here is another interior picture from a slightly different angle.
This is how it looks on the interior.
Below is an example of how NOT to do it.
Here are examples of different types of stairways using posts and not mortar.
These are huge log slices screwed, glued and bolted to each other and a central bearing post.
This final photo has a large center post, with stair treads lag screwed to a railing and then bolted to the post. The railing is a single piece of ash that was boiled in a pipe and then bent to shape and lag screwed into the railing stringers.
