Mortise and Tenon White Pine Log Stairs
This item is priced on a per-tread basis.
Our Mortise and Tenon White Pine Log Stairs are milled from kiln-dried Eastern White Pine timbers. We offer both Timber Style and Half-Log variants of treads and stringers, which provides multiple options for customization. The mortise and tenon joinery of these stair systems use traditional techniques accompanied by modern design for a sturdy and timeless product. Each stairway is then pre-constructed at the end of the fabrication process to ensure that the stairway will fit together exactly as intended when you unpack it at your job site. Since our manufacturing process eliminates the need for modification or retrofitting, these stairways can be installed by anyone with some woodworking experience and power tools.
Mortise and Tenon White Pine Log Stair Features:
• Mortise and Tenon joinery
• Highly-precise fabrication process
• Code compliant
• Fully customizable with 4 different tread and stringer combinations
• Convenient and accurate ordering process
• Quick and easy installation
Included Items:
• Two Eastern White Pine stringers milled to your specifications.
• All stair treads needed for your stairway, milled to fit specifically with your stringers.
• All hardware needed for stringer-to-tread connections and wood plugs to fill the countersinking holes.
• A DVD from the manufacturer providing step-by-step instructions on how to install your stairway.
• Log Stair Railings are not included with a log stairway order. We offer a wide variety of log railing options that can be paired with your log stairway.
Special Cuts:
• Stringer ends are cut at an angle to fit the header and floor at no extra cost.
• Optional Birdsmouth can be cut to fit over the landing/floor opening for an additional cost.
• Optional cut to remove 2" or 3" from the radius of half-round log stringers for a planed, flat fit against the wall. The 3" cut requires the stringer be bolted to the wall for maximum strength and should not be free floating.
• In the case that your stairway needs to fit against a wall, our mortise and tenon log stairways can be planed (flattened) on one end. This cut allows for the stair treads to be longer, while still keeping the characteristic radius edge of the log stringers.
Mortise and Tenon Joinery:
Mortise and Tenon joinery has been used for thousands of years for its simplicity and efficient design. Each tread has a 2x6" rectangular tenon milled from both ends that will fit into a stringer at each end of the tread. To secure the mortise and tenon joint connections, each stringer is pre-drilled for 3/8" lag screws and feature 1" countersinking holes for the included finishing plug. These plugs may be trimmed flush with the face of the stringers or left to protrude for a more traditional look.

• Lengths: Available up to 12 "
• Texture: Fresh Sawn (Circle-Sawn Texture Available)
• Typical Lead Time: 2 weeks
• Shipping Options: Each stairway is disassembled and palletized for efficient shipment via LTL Carrier, Flatbed tractor trailer, or Roll Back. Shipping method is determined based on location and order size to minimize cost.
Fabrication Process: Using customer measurements, a 3-D CAD drawing is made, detailing the precise rise, run, gap size, and stringer dimensions at the landing and header. Once the design is finalized, CNC machines precisely cut each component, which is then assembled to verify accuracy and eliminate on-site trimming. The processes used in manufacturing these log stairs greatly increases the strength of the stairway, eliminating stringer deflection or the need for a center support. With the treads and stringers so meticulously cut, the fit, as well as the rise and run measurements are guaranteed to be consistent along the length of the staircase. Mortise and tenon joinery is known for its craftsmanship and will surely add an interesting and timeless feature to any space.
