The Difference

Published in Item

You know it when you see it - so they say. But creating that difference takes a whole new level of commitment.

North Star Fabrication and Machine is different. Not just a fabrication shop working from drawings, we are a partner in producing market-ready products. Seldom a day goes by where we don’t inquire about the best way to complete an engineered expectation, or catch an omission in a parts list, or recommend a cheaper or more efficient method of construction. Culturally, we are just conditioned to think beyond the page.

We may bend steel, weld components, wire control systems, plumb hydraulics or design power systems - but at the core, we are problem solvers. We think in three dimensions, measure our materials in tons. We understand maximizing profits and meeting deadlines. We are partners in your success.

Jim Denny

Owner - Vice President

With over 30 years experience in metal fabrication, Mr. Denny is our Master Fabricator. We are hard pressed to find something in fabrication that he hasn’t mastered in precision production. Well versed in mild steel, stainless, titanium, cast iron, brass, bronze, etc., Jim has welded it all. He has a deep background in machining and industrial construction including hydraulics, and electrical systems. When he isn’t directly supervising large format projects, Mr. Denny is sharing his vast knowledge with our capable production staff. If you have a question about what is possible, he’s your resource.

Seth Vincent

Operations / Project Manager

Projects large and small benefit from the supervision of our Production Manager. For nearly 20 years, he has been a staple of the North Star family and adds an out-of-the-box element to our management team. With a talent for quickly understanding the vision, Mr. Vincent has knack for solving complicated problems from rough sketch to fulfillment and maximizing our production staff. If it can be done - Seth can get it done.

About Us

Published in Misc


North Star Fabrication and Machine grew out of the prosperity of the Douglas County lumber boom in the early 1980’s when Jim Denny partnered to work with Norm Stone. From those early years producing for various customers, operations grew and relocated several times before landing on Calapooia Street in Sutherlin, Oregon. Standard projects included asphalt production components, control van systems for on-site operations management, various logging equipment, and large format wastewater treatment components.

In the mid 1990’s North Star Fabrication and Machine was officially born. Enjoying fantastic growth in material handling machinery design and production, North Star made a footprint in the material specialized production equipment of several industries until economic changes hit the country.

From those humble beginnings and through tougher times, North Star has been focused on one core value - precision. Precision in production, manufacturing and customer service.


At North Star, we take being precise very seriously. And, precision manifests in ways that most people might not consider. Obviously, precision in the manufactured product is paramount - we can hold tolerances! But consider precision in relationships - anticipating best outcomes, treating our customers like family, creating partnerships from strength to advance mutual success.

Precision is our philosophy, beyond just our practice.
