Part VIII: Layout Without Windows At BCMC in Jacksonville in 1990, the PC had begun to “steal the show,” especially that of the upstart A.C.E.S. Their layout program was a quantum leap over the decade old work of C&G Micrographics on the Apple Computer. It also had several...

Part VII: A Computer for Every Designer In 1980, for the first time, I witnessed the PC doing trusses. Then, over the next 10 years, I watched that machine take over every designer’s desktop. Getting to that end, though, wasn’t easy. Unprecedented technological change roiled our...

Part VI: Desktop Engineering Rocks the Design World One man, an accomplished CM, set out to ramp-up the efficiency of truss designers in the Eighties: Mr. Leonard Sylk. He did it by pioneering the in-house computer, and its user-friendly software. By use of this tool, he envisioned a plant...

Another year has come and gone, and what an invigorating year it has been for most companies. Net profits after taxes for most component manufacturers were in the high teens to mid-twenties—at least for those who do not allow for never-ending excuses. Once again, it is time to reevaluate...

Why are equipment sales booming when near-term housing starts are projected to be flat?  Possible reasons are: CMs know better and expect good growth and need more capacity. Some markets will grow well and others will contract. CMs buying equipment expect to do better on the same...

Part V: A Prequel to Hands-On Design When Lou Lewis showed our engineers his $395 HP35 calculator in 1973, they barely blinked, but several in the truss industry did recognize its value. Perhaps we were too focused on our mainframe computer, and too invested in the programs that we had...

Part IV: In-House Computers Ten years after we installed our first computer, our turnaround of truss designs remained unacceptable. But one evening in the late Seventies, I saw daylight when a red, white, and blue van pulled up to our St. Louis office. I recall my wonderment back then, while...

“Good judgement comes from experience. And experience? Well that comes from poor judgement.” Some of us are old enough to remember Dean Martin. Whether he stated this quotation about experience and poor judgment, I will never know. But let’s face facts—it has...

Part III: In-House Computing (Almost) In 1971, for the first time, both On-Line Data and Gang-Nail, Inc. put computer software at the fingertips of truss designers. By 1973, our company responded, and so did most of our major competitors. This innovation was wrought out of near desperation on...

Optimization… In general, most plants want to mix up the cutting list, while still controlling the order that the members cut by the saw. This allows some gains in waste/cost to be had by combining members but still allows the cut components to be stacked easily according to truss once...
