The photo shows a 2 x 4 truss with an ANSI/TPI 1 non-compliance issue. This is something that never should have happened! Can you spot the problem? [For photo, See PDF or View in Full Issue.] If you shouted, “a missing connector,” then give yourself a gold star! As I was ranking...

Everyone who uses lumber in trusses understands that defects in lumber can impact truss performance in different ways. Some defects are not important but others will affect truss performance and can even cause truss failure. [For all photos, See PDF or View in Full Issue.] In the first photo,...

Originally intended as an improvement in lumber manufacturing, most dimensional lumber used for framing has a radius corner created during the planing process. The rounded corner radius is intended to make the lumber easier to handle and can improve the lumber’s performance because sharp...

Before leaving the subject of floor trusses, two machines deserve special attention, the Tiger Cat and the Structur-Span. Both included features that were way ahead of their 1970s provenance and both were markedly faster than even present-day machines. Both plated the truss with a single pass,...

Building intricate floor truss details may bedevil a robot, but they provide the inherent advantage of floor trusses over I-joists. There are also things that floor trusses can do that I-joists cannot. And they facilitate the most efficient use of materials. Visiting an I-joist cut-off yard...

It seems like a simple thing—connect lumber together with connectors creating a top or bottom chord for your floor trusses that exceed your lumber length inventory. It’s one of the simplest applications of metal connector plates. But, while the task seems obvious, there are several...

New inventions may fade away, but most provide valuable lessons, like the concrete truss machine. Not many of these were built, but they seemed to Cal Jureit to be the logical match for his new truss plate, and they set the course for all his future machines. Jureit had to have been...

Our contemporary floor machines were ready for the resurgence of demand that has followed the pandemic. These new models had many fascinating features, accumulated from the multiple iterations before them. They were more durable, they lessened labor, and they built a quality truss, embedding all...

Component manufacturers learned one very painful floor truss lesson in the 1970s that needed to be remedied in the 1980s – nightmare repairs can result from plates not being fully embedded. That predicament usually resulted from insufficient tonnage to fully press the larger plates found...

A robot visited the BCMC Show floor again this year, and, for the first time, really showed its stuff, picking truss plates like there was no tomorrow. And its dynamic demo couldn’t be missed, as House of Design (HoD) positioned their Nail Plate Picking Cell right at the exhibit’s...
