It never ceases to amaze me how “simple” things can become so complicated. I’m sure I’m not alone in this quandary – the feeling that you’ve stepped into a maze and now struggle to get out. Simple Beginnings, Complicated Developments Last spring, I...

How does a component manufacturer determine what fabrication tolerances should be used during truss design? To answer that question, we first need to clarify what is meant by “fabrication tolerance.” Per ANSI/TPI 1–2014, the guidance is 3.3.2 Fabrication Tolerance. All...

Over the last couple of articles, I’ve spent some time discussing improvements that would improve both the energy efficiency and the ability of the truss system to withstand extreme weather conditions. If you’ve read those articles, you will know that I think it is ridiculous that we...

Each generation has to learn all the life lessons either through their own mistakes or the counseling of the older generation. The vast majority of us wish not to repeat the same mistakes and, if possible, avoid them altogether. If you wish to avoid embarrassment, whether you are new to being an...

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...

As a new year begins, now is the time to ask: do I need a 3rd party auditor? If you don’t have one, then you need to take a hard look at your business. As companies in other industries have learned too, using a third party to conduct all audits throughout an organization (or supplementing...

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...

MSR Lumber has a long history of being the right choice for component manufacturers. This reliable and consistent lumber grading system revolutionized the construction industry when it was introduced to the market in the 1960s, and it continues to be a mainstay for truss producers decades...
