Canadian Hardware Brings Timber Into View

timberlinxOne of the biggest differences between discerning homeowners and the professionals who build and renovate houses for them is the tug-of-war that sometimes emerges between the desire for a fancy appearance and the need to stay practical and affordable. Homeowners often want features that are outside the budget of the project or beyond the skill level of the tradespeople available for a contractor to hire. The quest for efficiency, coupled with insufficient skills in the labour force, are the biggest reason why so many of our great Canadian trees get sawn into planks and hidden behind drywall, rather than sawn and joined into beautiful beams that remain in full view as part of the design. I’ve used a little-known Canadian product hardware system called Timberlinx (877.900.3111) on a few of my projects, and it goes a long way to making exposed timber designs more affordable for homeowners, and more doable for contractors.

Timberlinx is a system of simple, hidden hardware that eliminates the need for time-consuming, skill-dependent traditional joinery typically used for connecting big wood into parts of a building frame. I first learned about Timberlinx almost 10 years ago. The system uses metal tubes inset into holes that span the connection between adjoining timbers. Expanding metal pins fit into oval holes at the ends of each tube. When you make these pins larger by turning a big bolt in the centre, it draws the joint tight. I’ve used the Timberlinx system to connect solid wood timbers as well as engineered glue-laminated beams and it works equally well with both.

timberlinxDrilling accurate holes is key, and the system comes with a robust metal drilling jig that guides a 1 1/8” diameter self-feeding drill bit square to the face of the wood. This approach bores the necessary intersecting holes for the system – one long hole for the central tube, and two shorter ones for the expanding pins. There are a handful of different variations on Timberlinx hardware, depending on the specific joinery situation you’re facing.

You’d have to be something of a mechanical genius to understand exactly how Timberlinx works from my short description here, but that’s okay. What really matters is that you realize there’s an efficient alternative to traditional timber framing methods, and it’s probably not something your contractor knows about. Timberlinx isn’t something you’ll see in every hardware store.

Although I’m a purist when it comes to wood, and I do prefer and use traditional joinery methods in some of my own work, I consider a little bit of cheating with hidden metal hardware a small price to pay if it means replacing hidden 2x6s and 2x10s with the magnificence of grand, exposed 6×6, 8×10 and 10×12 timbers.

Some of these are stationary, one-man operations, while some sawyers offer a traveling sawmill service. I’ve also ordered beams from my local building material supplier, delivered to my site four weeks later with shingles, plywood and insulation. Cutting timbers to length requires special tools, since regular power saws don’t cut deeply enough, though the options are simple and affordable. I use an electric saw fitted with a Prazi beam cutter chainsaw bar, or a gas-powered chainsaw fitted with a support shoe called a 75º Head Cutter (; 888.798.4499) that keeps it cutting square.

As Canadians, we enjoy access to wood that most of the rest of the world can only dream about. And while there’s certainly a big place for conventional lumber framing methods, doesn’t it make sense to let a little bit more of our extraordinary Canadian timber show through?
