thing of beauty is a joy forever.” The familiar phrase was penned by John Keats in 1818 as the opening line to his poem “Endymion.” John Woolworth is also making things of beauty using stainless, aluminum, bronze, brass and steel. He established Pfunder Metalwerks in 2015 to design and fabricate custom products that range from lighting fixtures, table and bench legs to retail store display cases and structural parts. The company name is a nod to his family’s German heritage.
Woolworth’s eye for detail and his knack for combining function and quality with exquisite lines have boosted growth for his Sonoma, California-based business year over year. When a commercial property developer in Fairfield, California, commissioned Pfunder Metalwerks to contribute to the design/build of 14 tables and 28 benches for a new coffee shop’s interior and exterior spaces, Woolworth went shopping for a new CNC horizontal bender.
An internet search led him to Boschert USA in Butler, Wisconsin. The company is a distributor for Stierli-Bieger bending/straightening machines. “I always wanted to be able to make complex shapes,” Woolworth says. “I looked at several manufacturers’ horizontal benders, but I wasn’t sold on any of them. None of the benders had a backgauge and you couldn’t program bend angles. I was intrigued with the Stierli. Its CNC-driven horizontal bending capability met my immediate needs with room to grow.”
The project called for the tables and benches to feature bent steel bases that could support tops made from Ipe, or Brazilian walnut. The dense wood is harvested from forests in Central and South America for its beauty and durability. To create the legs, Woolworth turned to Euclidean geometry to produce a CAD drawing that specified a trapezoid shape with welded radius corners using 3/8-in. by 4-in. steel flat bar. The legs would then fasten into a plate on the undersides of the benches and tables. Each bench and table leg had to be bent perfectly to achieve a clean weld and precise hole alignment.

“Each piece met up perfectly, and I was able to weld without clamping. When you do that kind of work manually, the angles and lengths are never exactly the same,” he says. “But to achieve the aesthetics you want and the functional performance you need, the pieces have to provide a firm, level foundation. The Stierli helped deliver that.”

For production runs like the table and bench legs, Woolworth can save program settings and call them back up for future jobs. In addition to fine work with high aesthetic appeal, Woolworth also produces industrial parts like electrical enclosures for municipal applications. “People need that type of work too,” he notes.
Woolworth’s ability to communicate with customers and his attention to detail keep jobs pouring through his front door. These qualities are also what sets Boschert’s service apart from other equipment suppliers. “Although Boschert services me from another location, I have access to remote support and troubleshooting,” he says. “They have been really responsive. Even the president of the company flew in and conducted the demonstration run once my machine was set up. That surprised me.”
The Stierli CNC horizontal bender provides repeatable bend angles while reducing processing time and boosting throughput.

For now, Woolworth is busy building his business with a short-term plan that includes some new equipment so he can transition into more production work. The metal fabricator is looking at producing parts for the renewable energy and solar markets.
“I’ll still continue to do the fine work,” he says, “but I want to add employees and evolve into more of a pillar in the community. California is one of the most expensive places for this type of work. We can’t keep outsourcing everything. I want to be part of the next chapter of manufacturing here in the U.S.”
