Shop Solutions: Shop's Diversity Rides on Waterjet Cutting
What do a 260-mph (418-kph) Ford Mustang funny car, a 48" (1.2-m) manhole lid, a kitchen countertop and a 56' (17-m) semitrailer have in common? They all center around Brian Hough’s shop, West Coast Steel Fabricators (Eugene, OR), and benefit from versatile affordable waterjet cutting technology.
Brian Hough’s business extends beyond the West Coast Steel Fabricators job shop and into three other divisions—OTI, Olympus Trailers, and Cascade Truck Body & Trailer Sales. OTI manufactures equipment for wastewater treatment facilities; Olympus Trailers builds large motorsports and utility trailers; and Cascade Truck Body & Trailer Sales up-fits trucks for service and heavy-duty industrial use.
And about that Ford Mustang funny car, Brian also runs his own NHRA Top Alcohol Funny Car racing team, Brian Hough Racing. He’s also the team’s championship driver.
West Coast Steel Fabricators began operation in 1979 and does custom fabrication work that includes conveyors, bins, hoppers, tanks, trusses, ductwork, and silos, among others. In essence, listing what products the versatile 50-person shop has not created would be easier. Besides his regular customers, Hough shares the shop’s fabricating expertise and capabilities with all his other divisions, including the Top Alcohol Funny Car racing team.
A few years ago, Hough looked to expand and diversify his business in the face of the new economic reality. He wanted to expand his custom steel product offerings and elevate component quality to higher levels. That is when he incorporated his first abrasive waterjet cutting machine into his shop.
With abrasive waterjet technology, Hough now handles a wider range of production runs, including fast prototype development. He is able to quickly turn around highly accurate parts without the hassle of tool changes or complex fixturing. Plus, compared with his other production equipment, abrasive waterjet cutting generates much smoother surface finishes, which in many instances eliminates the need for secondary machining.
“I had long been interested in waterjet cutting, so when I was ready, I contacted OMAX Corp. The company appealed to me because it is nearby in Kent, WA, and is a close-knit, family-oriented, US-based company,” said Hough. “Once I decided on a machine, OMAX had it here within three days, and that same day, I was up and running.”
Hough’s machine is a Maxiem 1530 JetCutting Center. First introduced in 2009, the Maxiem line has proven its ability to meet customer demands for cost-efficient, versatile waterjet cutting technology. More than 20 different sizes currently comprise the Maxiem line, and each model incorporates OMAX’s proven direct drive pump technology and Intelli-MAX software suite. Hough’s 1530 model employs an X-Y cutting travel of 10' 2" × 5' 2" (3 × 1.6 m)
“Where the Maxiem 1530 really shines is in producing parts that are beautifully finished right off the machine. We have eliminated up to two hours of finishing time from most parts, as well as gained back the manhours usually spent deburring and cleaning parts,” said Hough.
The shop recently added the OMAX Collision Sensing Terrain Follower accessory to its 1530. The accessory has especially been an asset at OTI, Hough’s anaerobic digestion equipment division, which contends with uneven part surfaces on a daily basis. Prior to adding it, the shop’s operators continuously experienced instances where the machine’s cutting head would encounter an uneven surface height and automatically shut the machine off.
“Initially, we didn’t realize the need for the Terrain Follower. Fortunately, OMAX designs its accessories to retrofit onto any machine already in the field, so adding it was fast and easy. Now if our plate stock has a bit of a wave to it, the machine just follows along seamlessly and without any issues,” said Hough. “No special programming is necessary. It just works when we need it to.”
Prior to waterjet, Hough’s businesses had relied on high definition plasma cutting. And while that process still accounts for a large amount of his daily operations, it is unable to compete with the Maxiem waterjet in terms of accuracy, especially when cutting the shop’s mild steel, stainless steel, and aluminum.
“With our high-def plasma we can get speed but not accuracy. Parts come off the machine and must be polished, the edges cleaned up and a reamer run through the holes. These operations add up to an extra hour and a half of time tacked on to every part,” said Hough. “With the waterjet, we can do the same amount of parts as with plasma, but when the waterjet parts are done, they are done and have much higher quality finishes. So much so that we now have internal guidelines stating certain parts can only be produced using the waterjet machine, specifically those parts that will be customer facing. We want to show off these parts. It gives equipment a high-tech feel. Parts are cut perfectly and look beautiful every time,” said Hough.
In addition to OTI, the precision of waterjet cutting really shines for the Olympus Trailers division of Hough’s businesses. These high-end trailers are built for demanding markets such as the motorsports industry, and customers expect tight tolerances and elegant finishes on every part.
The trailers feature extensive aluminum constructions, including all-aluminum framed cabinets with stainless steel countertops in work areas and heavy-duty aluminum doors throughout. The company’s semi-trailers can measure up to 56' (17 m) in length and feature lounges with DuPont Corian countertops, drop-down LCD satellite TVs, full size refrigerators, and even custom marble floors.
For his racing team, Hough uses the Maxiem 1530 to help reduce the weight of his funny car, cutting precision parts such as motor mounts and brackets to his exacting specifications. NHRA drag racing is all about extreme straight-line speed. Often a team’s only path to gaining a few hundredths of a second in the quarter mile is in reducing the weight of its car. Teams like Brian Hough Racing look to gain every possible advantage, and Hough uses his waterjet machine for this purpose every chance he gets.
“When it comes to making parts for the car, the great thing about having the waterjet machine is how quickly I can go from idea to prototype. I can sketch out an idea and quickly turn that into action on the machine,” said Hough. “We can turn around a new bracket to try on the car in rapid fashion. And if that doesn’t work, we go back to the drawing board and come up with something new. The Maxiem allows us to do a lot of experimenting in a very short amount of time.”
In the shop, Hough’s employees frequently experiment with new applications for the waterjet machine, working to accomplish even more with the equipment. They are now able to cut practically any type of material, from rubber to UHMW to aluminum to stainless steel and carbon fiber. “We are now even cutting the wood for our skids with the Maxiem waterjet,” said Hough. “All our equipment ships out on wood skids, which require cutting prior to shipping. Thanks to one of our experiments, we recently switched to making those cuts with the waterjet. As a result, we took a job that previously ran between 7 and 10 hours and reduced it to only three hours. And because we complete the job so quickly, we have time to also cut our company logo into the pallets, which we had never done before.”
Now that abrasive waterjet cutting is fully integrated into all of his businesses, Hough can’t envision succeeding without the technology. “It is something that I look back on now and wonder how we were able to do it all along without a waterjet,” Hough said. “The capability was something that we should have always had in the shop. We will definitely continue to move forward, and we are absolutely considering another machine, most likely with a larger table size. Our current machine is already used much of the workday, and as we market our machine’s capabilities to clients in the area, it has become obvious that we will eventually see the demand for running two machines. When that time comes, I will certainly call OMAX.” ME
