Does Your Lumber Have a Shelf Life?

Glenn Traylor

Just like some foods, lumber kept in the right environment will store for an indefinite length of time. But just like food, lumber kept in sub-par conditions will have a shortened storage period. If you’re not storing your lumber properly, you may have to question whether it can/should...

What is the Most Common Fabrication Issue That Impacts a Truss?

Glenn Traylor

The most common problem typically encountered is excessive defects in the plated area of the truss. While some defects are acceptable in the plated area, the degree of defects depends on the actual joint situation and forces at the joint. Connector sizes are controlled by design, handling,...

When Fabricating Components, Always Consider the End Result

Glenn Traylor

How the product will be used is a very important consideration when designing components, and it also comes into play during fabrication. The attic trusses in the photograph have a wedge installed at the wall–ceiling intersection. This is the intended design. Deeper in the rack,...

Mind the (Member) Gap

Glenn Traylor

Everyone knows that member gaps can be caused by uncalibrated saws and poor jigging stops during truss set-up. But did you know the most likely cause of member gaps is the lumber carriage shifting or moving the lumber at an angle, thereby causing a skewed cut? This is especially true when a gang...

Do You Need 100% Inspected for Proper QA?

Glenn Traylor

A process that requires the inspection of each individual unit or component received from a process or manufacturer is said to be “100 percent inspected.” When fabricators initially consider a quality program, this is what they imagine is necessary. This 100% process, however, is...

There’s More to Lumber Qualification Than Just the Grade Stamp!

Glenn Traylor

Picking usable lumber involves more than just the initial grade stamp. We can think of the stamp as the first step, but we can’t stop there. Truss fabricators depend on the lumber supplier to provide effective grading protocols that will produce materials with predictable design values....

Wedges—Misunderstood and Underappreciated?

Glenn Traylor

The lowly wedge sometimes gets very little respect. If your plant is doing it right, the wedges usually are cut from drops or culls. That’s a good way of doing it, and it sounds very simple, but not just any piece of wood is suitable for a wedge. There are important qualifications that...

Is There Such Thing as Too Much Pressure?

Glenn Traylor

Too much pressure is not only a problem in our lives, it can also be a problem in our plants. One of the most important issues when manufacturing quality trusses is plate embedment. Without proper embedment, the connector plate cannot adequately transfer load forces through the members down to...

Seeing the Need for Quality Assurance AND Training

Glenn Traylor

When you look at this photo, what do you see? The photo is an actual picture taken during a plant audit, but just imagine this was taken at your truss plant. In the photo, the second side of the floor truss is set up in the floor machine with the connector plate positioned and ready to receive...

A Case for Providing More Design Info to the Assembly Table

Glenn Traylor

It’s true that, by nature, the materials currently used for wood trusses can vary in strength and properties. Given a specific lumber size and grade, truss builders often need to evaluate lumber picked, cut, and provided to build the specific job at hand. After verifying the lumber grade,...
