The Development of the Truss Plate, Part V: Frenetic First Get-Together

Joe Kannapell, PE

Twelve competitors faced one another for the first time—but only because they had to. Each of their fledgling plate businesses was threatened by a July 31 deadline from the Federal Housing Administration (FHA), and they had less than three weeks to put together a design criterion for...

The Last Word: The Last Word on Automated Material Handling

Joe Kannapell, PE

With automated saws and auto-jigging tables, what remains is automated material handling, and that’s what we find at Builders FirstSource’s (BFS) Austin plant. House of Design’s (HoD) robotic roof line there extends the floor truss pre-plating methodology found at their Atlanta...

The Development of the Truss Plate, Part IV: Competition Intensifies

Joe Kannapell, PE

After Cal Jureit’s impressive debut at the 1958 NAHB Show, lumberyards and builders across America were anxious to start trussing, but they encountered several obstacles. Their deluge of inquiries couldn’t all be answered, and most were far away from the South Florida source of...

The Last Word: The Last Word on Pre-Plating

Joe Kannapell, PE

Just as Trussmatic brought back hydraulic plate pressing, House of Design has resurrected pre-plating. Both practices proved themselves in the early days of our industry, but both required disciplined shop floor management, and each had limitations. [For all images, See PDF or View in Full...

The Development of the Truss Plate, Part III: The Ingenuity of Carol Sanford and Cal Jureit

Joe Kannapell, PE

Carol Sanford’s invention didn’t equal Cal Jureit’s, but he made up for it with his head start and his aggressive marketing. Sanford had filed for his patent in March 1954, two years ahead of Jureit’s September 1956 filing, and had a plate design that was relatively...

The Last Word: The Last Word on The First Trade Show

Joe Kannapell, PE

After this year’s BCMC, it’s worth considering how far our industry has progressed since we first went to a trade show. The year was 1958, and the National Association of Home Builders Show (NAHB now IBS) was the only way to reach a national audience. Fortunately, we had one...

The Development of the Truss Plate, Part II: Cal Jureit’s Invention

Joe Kannapell, PE

Civil engineer Cal Jureit had moved on from wood structures to concrete foundations, but not completely. While he was engaged with the problem of building houses on Miami’s marshes near the Everglades, he had left the problem of wood connections unresolved. Perhaps his ongoing work on Dade...

The Last Word: The Last Word on Totally Robotic

Joe Kannapell, PE

Attendees at BCMC 2019 stood safely right next to an awesome gesticulating robot and became immersed in observing record-breaking truss building – virtually, that is, through a VR headset. Back then, Trussmatic robots hadn’t made it stateside, and hadn’t yet handled our crazy...

The Development of the Truss Plate, Part I: The Perfect Storm

Joe Kannapell, PE

A nearly perfect confluence of circumstances combined to create the truss plate in South Florida. The wartime home-building hiatus, the post-war baby boom, and the northward (from Cuba) and southward (snowbird) migration to Florida all combined to skyrocket the demand for new housing. But what...

The Last Word: The Last Word on the Promise of Robotics

Joe Kannapell, PE

When $20 Billion behemoth Builders First Source (BFS) launched a robotic truss line in April, CMs were surprised that they would select House of Design (HoD)’s first truss machine, and the industry’s first robotic floor truss line. Remarkably, after just over 3 months, they’ve...
