Gary re-designs the gutter machine a second time to produce the “1700”, which proves to be his first successful U.S. patent and results in the sale of approximately 12,000 portable gutter machines made in the Knudson name for the next 30 years. In addition, Gary and Art work on other designs and products including the K-Span arched metal building system for on-the-job production of “Quonset” type steel framing. Gary receives 9 U.S. patents on the machinery and process and an additional 5 on a longer revision of the system with 20 or more corresponding foreign patents.
