Home Building Technology, Part XVI: Roller Equipment Alternatives Joe Kannapell, PE It’s about time that a serious contender challenges the dominance of the roller gantry. Its life has been extended with lasers and auto-puck systems, but no upgrade so far has taken the hammer out of the hands of assemblers, its greatest drawback. The only alternative, the vertical press,... Read More May 2026 Issue #18322 Page 10
The Last Word: John Houlihan’s Contributions Joe Kannapell, PE A quiet and unassuming man, John Houlihan was ushered into our business by the charismatic Dave Chambers, and together they built the foundation for today’s labor management practices.

The New American Home at IBS 2026 Joe Kannapell, PE Will trusses will be part of new American homes in the future? That question has been the reason I keep a close eye on the home built for NAHB’s International Builders Show. Since 1984, this off-site exhibit, “The New American Home” (TNAH), has presented the latest innovations... Read More April 2026 Issue #18321

Home Building Technology, Part XV: The Rebirth of Wood Joe Kannapell, PE Wood was not held in high regard in the truss drafting department where I began working. Our fabricator customers often wanted their trusses designed with “old lumber,” meaning the obsolete size of 1-5/8” x 3-5/8”, even though the 1.5” x 3.5” size had been in...

The Last Word: Truss Math on Your Phone Joe Kannapell, PE Few, if any, pieces of wood will pass the scrutiny of an 8’ level, and the superintendent of Bill Milburn’s homes in Texas wielded his level like a weapon.

Home Building Technology, Part XIV: Truss Equipment Proliferates – Assembly Joe Kannapell, PE You could say that Carol Sanford flipped the script on machinery, like he had in so many circumstances throughout his career. In the 1950s, when he couldn’t sell his modular homes in Ohio, he shipped them to Florida. When he couldn’t sell them there, he turned to selling site-built...

The Last Word: Bill McAlpine’s Legacy Joe Kannapell, PE The name “Bill McAlpine” has such resonance in the component industry that when ITW acquired the company and removed his name, they soon found value in returning to the Alpine moniker. There are many reasons McAlpine earned that singular honor, but one of the least recognized is... Read More February 2026 Issue #18319 Page 190
Home Building Technology, Part XIII: Truss Equipment Proliferates – Component Saws Joe Kannapell, PE As housing demand accelerated in the 1960s, builders increasingly turned to trusses. But, lacking better equipment, truss shops had trouble scaling up to fill their orders. Early shops had little more than radial arm saws to cut members and wood tables to assemble them. They had exhausted every... Read More January 2026 Issue #18318 Page 10
The Last Word: (When) Will AI Overtake the Truss Industry? Joe Kannapell, PE Artificial intelligence (AI) has been 70 years in the making since eminent AI pioneer, John McCarthy, coined that term in 1955 to describe “the capability of a machine to imitate intelligent human behavior.” Truss software has been 50 years in the making, with scant penetration of AI...
