System Installations

Sean Hubbard

Thirty years ago, equipment installations looked considerably different. Often, the equipment was installed using the customer’s maintenance staff and even the truss building crew. Working with new crews on a weekly basis, who were skilled in component manufacturing but had limited...

Sixty Years of Machines, Part VIII: Trackless Gantries

Joe Kannapell, PE

In the 1990s, a storm began brewing in the component business. It started on the Eastern Seaboard when Carolina Builders bought a truss plant in Tidewater, Virginia. Later, it gained strength when Builders Supply & Lumber (BSL) opened a series of greenfield plants. And finally, it reached an...

Sixty Years of Machines, Part VII: Gantries—Running Off the Rails

Joe Kannapell, PE

One glaring gantry glitch, truss plates falling off, still needed to be addressed in the early 1990s. Missing bottom plates interrupt production, or worse, compromise quality. Sometimes an uneven table surface is the cause. But often the gantry mechanism is to blame. Tolerances are surprisingly...

The Value of a Dollar

Sean Hubbard

Decades ago, I learned the value of a dollar as many of us did from our parents and grandparents. At that time, our industry was predominately family businesses. I don’t recall discussing age, however as we grow older, age is simply a number. That was never more evident in our family...

Rethinking a Linear Saw Linked to Two Workstations

Todd Drummond

It seems some people are upset that I made such a public statement with my latest advertisement – “Pairing a Linear Saw with Two Workstations with Each Having Two Assemblers will Cost Your Company Millions in Lost Net Profits.” Specifically, I’m talking about linking...

Sixty Years of Machines, Part V: The Gantry Gains Ground

Joe Kannapell, PE

The roller gantry had two major obstacles to clear in the 1970s, both erected by its inventor, Carroll Sanford. Both were delineated in hard-to-evade U.S. Patents. The first was on the machine itself and the second was on the connector plate that it required. The simplicity of the gantry machine...

How Do Your Manufacturing Errors Rank on the List?

Glenn Traylor

Eleanor Roosevelt once said, “Learn from the mistakes of others. You can’t live long enough to make them all yourself.” Apparently, she never worked in a truss plant, where I think everyone will make them all at least once. But humor aside, let’s take a look at the...

Sixty Years of Machines, Part IV: Early Roller Gantries

Joe Kannapell, PE

The roller gantry dominates today’s truss production, but it hasn’t always done so, despite the fact that it hasn’t changed much over sixty years. The reason for its relatively slow ascendency is found in its origins and in its adaptations over this period. And along the way...

Sixty Years of Machines, Part III: Table Presses

Joe Kannapell, PE

More CMs are “doing it right the first time” via vertical presses, taking advantage of their flexibility and the quality of their production. But few realize that some of the most successful plants in our industry started with table presses. These presses have always had the...
