Sixty Years of Machines, Part XXIV: Opposites Attract Joe Kannapell, PE A David and Goliath struggle was brewing over the linear saw, and it was ready to boil over at BCMC in October 2002.

Sixty Years of Machines, Part XXIII: Linear Saw Wave Joe Kannapell, PE As the new Millennium dawned, it still hadn’t dawned on CMs that a linear saw was a sure bet.

The Last Word: Coming of Age at BCMC Joe Kannapell, PE What I experienced at the truss industry’s first trade show was the bare bones beginning of fifty years of industry progress.

Sixty Years of Machines, Part XXII: Linear Saw Convergence Joe Kannapell, PE In the 1990s, two small town entrepreneurs tackled vexing cutting problems, but from very different angles, and their innovations set the table for today’s linear saw industry.

The Last Word: The Last Word on Making the Cut Joe Kannapell, PE Why did most of today’s saw technology come from small shops and not from large machinery companies?

Sixty Years of Machines, Part XXI: Rebirth of the Linear Saw Joe Kannapell, PE Entering the new Millennium, the linear fed saw needed to be reborn. Though CMs had boosted productivity with bolted-on improvements to their Metra-Cut type saws, they still couldn’t keep up with automated component saws. Yet they remained an essential part of the saw shop, even though... Read More August 2021 Issue #13265 Page 10
The Last Word: The Last Word on CM Disruption Joe Kannapell, PE Is component manufacturing ripe for disruption? Two foreign-backed entities came to our shores and tried to do just that for six years: Katerra with billions and Blueprint Robotics with many millions. Both were going to teach us how to build better, but with entirely different approaches. Out... Read More August 2021 Issue #13265 Page 142
