For our rustic log stairs we use the best in CAD and CNC machining to create
a beautiful log staircase. Whether you want a full log stairway, a mortise and
tenon half-log stairs, or a timber style staircase, we guarantee your rustic
log staircase will meet your specs, saving you and your builder imstallation time.
Using the dimensions you provide, we create a 3D CAD drawing of the log stairs
showing overall and individual rise and run, gap size between tread, and size
the stringer at the landing and header. Once the dimensions are finalized for
your rustic log stairway, our CNC machines cut the stringers exactly as the are
shown in the CAD drawings. You can choose from multiple styles of log staircases;
Coped log stairs, half-log mortise and tenon, timber mortise and tenon, or a
conventional style timber stairway.
Our coped log design creates the illusion of the treads floating upon
the stringers. Both the stringers and the tread are coped, or notched to fit
togeather one upon the other. We create a machined surface on both parts of the
stairs, which eliminates the need for on-site shimming or trimming. This
new process greatly increases the strength of the stairway compared to the "old"
method. Having a machined surface on both the stringer and tread shrinks the
amount of material removed from the stringer, eliminating stringer deflection
or the need for a center support. With
both surfaces machined, the tread fit on the stringers level and the individual
rise and run measurements are consistent from the top of the stairs to the
bottom. This enables the average DIYer to install their stairs in a day
with a helper or two. We include a 3 minute instructional DVD with every
staircase we ship that gives helpful pointers and tips to ensure an efficient
Our mortise and tenon design has the look of a more traditional stairway
with the treads attached to the inside of the stringer instead of floating on
top. With our CNC machining both the mortise in the stringers and the tenons
on the tread, you can be assured that the placement of each tread is exact and
the installation of the stairs expeditious. Each tread has 2" of tenon in each
stringer that ensures a robust construction, and a clean, finished appearance.
The timber stairway creates a more refined look with radiused corners and all
surfaces planed smooth.

Mortise and Tenon Design
Where there is a stairway against a wall, we can plane (flatten) the outside
of that stringer to allow for a flat fit on the wall. This allows for a wider
tread in most cases and also leaves a portion of the round on top of the stringer.
other companies use a square stringer for this application with no round on top.
Each tread has a 2" x 6" tenon on each end. The stringers are mortised to accept the tread. This mortise and tenon design ensures structural integrity and ease of assembly. We also counter bore the stringer with a 1" diameter whole to accept the 3/8" x 8" long lag screw and finish plug. All lag bolts and plugs are supplied. A complete stairway as described above is also available with square edge stock. The stringers are 3 3/4" x 11 1/2" and the treads are 3 1/2" x 11".
