Many years ago, early in my career as a truss designer, I was interrupted by the production manager. He loudly entered my office with a piece of 2 x 12 and a circular saw and abruptly slammed both on top of my drafting table that was sporting a newly created truss layout. (We did not have...

Four distinctly different types of truss plates came onto the market in the 1950s, but only two made it into the 1960s: the short toothed and the long toothed, neither requiring nails. These two types continued to evolve over the next decade, although along distinctly different paths, and under...

Throughout the 1950s, plate manufacturers kept busy improving their plate designs, while they paid scant attention to the machinery that CMs needed to embed them. But, in the 1960s, they began focusing heavily on machinery and laid the foundation for developments that would shape truss...

Among our industry’s unsung heroes, Walter Moehlenpah takes a close second place behind Cal Jureit. Both built pivotal, pioneering businesses, Jureit through his truss plate and Moehlenpah through his truss machine. Yet Jureit was bound to have the upper hand, as he was the truss...

As builders began demanding Gang-Nailed trusses, imitators answered their call with little concern for violating Cal Jureit’s patent. Even though his claims were technical triumphs, vetted by D.C. patent experts, they were quickly contested by two now-familiar figures, Bill Black and...

Quality, productivity, and speed are intertwined and impact each other. My previous article, Where is Your Focus on Manufacturing?, emphasizes that improving quality starts with implementation of the ANSI/TPI 1 standard—and, with that process, you will improve proficiency and speed. The...

In his series on The Development of the Truss Plate, Joe Kannapell is recounting many interesting details on the evolution of truss plates in the U.S. For another perspective, this article will focus on eight relevant nail plate truss inventions from Finland —two made by Matti Turulin, two...

The plated truss industry went bonkers around 1961. Truss fabricators were besieging suppliers for product and were willing to try nearly any plate or machine. Plate suppliers had to conform to the new testing and QC required by TPI-60, but machinery vendors had no guidelines beyond satisfying...

On July 5, 1960, in a marathon session, a dozen entrepreneurs set standards for a brand new industry, and, in the process, met a government deadline. These early truss plate adopters came well-prepared and didn’t hesitate to make far-reaching decisions. Fortunately, they left a detailed...
