The Advertiser - June 2017 | Page #30 Compliance with ANSI/TPI 1–2014 requires maintaining member to member gaps at less than 1/8 inch. An exception would be for floor truss chord splices where the limit is 1/16 inch. While building trusses, the code calls for tight joints. In a...

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...

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...

As housing boomed in the mid-1980s, truss plants needed better equipment. Among those was Heart Truss and Engineering in Michigan. Heart was also benefitting from booming auto plants nearby. Their production head, Bob LePoire, pondered how to keep up. Bob’s boss and Heart’s...

What makes up a great Quality Assurance Program? As you’ll recall, I listed 9 essential components for good QA in an article last year, “How Does a Fabricator Gain From a 3rd Party Audit?”. It’s no surprise that each one is rooted in the personal, on-site interaction that...

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...

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...

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...

Back in the days before Autoset C®, Matchpoint®, and Wizard®, truss set-ups and the truss profile were dependent on the truss builder’s ability to accurately jig the truss being built using cross reference information and data. For example, a heel to peak measurement was taken...

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...
