The element that defines a professional timber framer is the way in which the joints fit together. A good joint will stay tight and strong for generations. Timber members should neither be too large or too small and the joints should stay tight over time. All wooden beams will shrink & check as they dry - it is part of the unique nature of timber framed buildings.

Most of our joints are pinned together with 1-inch hardwood pegs. The geometry of the joint itself carries most of the structural load, and the peg holds the joint in place. When loads are extraordinarily large or when aesthetics call for it, we use heavy steel plates & bolts. All of our joints undergo in house engineering to confirm their strength and integrity.

Traditional Pegged Timber Joinery

Traditional Joinery

The traditional way to join timbers is with mortise and tenons held with hardwood pegs. It is a method that is strong, beautiful and time tested.

This photo shows traditionally joined rough sawn hemlock timbers held with one inch birch pegs. We prefer to use birch pegs for interior applications because of their strength, stability and their resistance to shattering when they are driven.

Heavy Timber Purlins and Truss

Joists and Purlins

The joists and purlins span between bents and trusses. They are typically held together with dovetails, or half lapped, shouldered and screwed with log hog screws.

Timber Purlin Installation

Joists and Purlin Installation

This photo shows dovetailed heavy timber purlins being installed between roof trusses.

Timber Truss with Steel Gusset Plates

Steel Connections

Steel gusset plates can be used to join timbers when the structural loads are high, or when the look of iron and timber is desired.

Timber and Steel Connections

Timber and Steel

A combination of traditional joinery and steel joinery looks great. In the photo to the left, the webs are attached to the king post with a traditional shoulder, and the tension in the truss is resolved with steel rods and tear drop shaped gussets.

Timber tension rod connection

Tension Rods

Tension rods are added to trusses to resolve the spreading forces in the roof while maintaining a sense of height. The tension in the rod is transferred to the timber with steel plates and bolts. More tension = more bolts. Vermont Timber Works always follows the best engineering practices and the NDS when designing connections.

Timber Truss with Tension Rod Connection

Timber Truss with a Tension Rod

This graceful arched truss works because of the tension rod. The top chords are in compression and the steel tie rod and hammer ties are in tension.

Post and Beam Post Base with a steel rod and plate

Post Bases

There are many ways to secure wood posts to floors and foundations. The method shown to the left is typical. A steel rod is epoxied into the foundation and drilled through the center of the post to a flat plate washer and nut. this connection secures the post laterally, and resolves uplift forces. A metal or plastic base plate is used to separate the post and concrete.
