The Bob Lewis Story

Bob Lewis started his company in 1975 in his garage in Torrance, California. With a Bridgeport Mill, a Chucker, and three drill presses, Bob got his big break with supplier approval from AirResearch. He then moved Bob Lewis Machine Company into its own 5,000-square-foot building in 1980 and began to build his company into a modern manufacturing powerhouse.

Bob Lewis Machine has built a solid reputation for excellence.

For the next several years, Bob Lewis Machine Company acquired new customers and focused on quality and customer service. More equipment was added, including CNC machines, to keep up with the growing customer base and demand for high-quality, precision-machined parts. From the very beginning, Bob Lewis Machine Company has focused on quality and reliability, building a reputation for excellence in the contract machining industry.

In 1986, Bob Lewis Machine Company moved into its present facility in Gardena, California. In a new, 10,000-square-foot modern manufacturing facility, Bob Lewis Machine Company continued to grow and prosper. The next twenty-two years saw many positive changes at the company. A comprehensive CNC programming department was added to support the growing number of CNC machining centers. Wire EDM, grinding and complete assembly capabilities came online to support customer requirements. During this time, Bob Lewis Machine Company came to be known as the company that likes a challenge. “We take on work that others will not do,” explains Jeff Lewis, vice-president. “Our unique capabilities give Bob Lewis Machine Company the edge when it comes to complex and tough-to-machine parts and assemblies.

For his victory, Uribe earned $28,851 and a new Ranger Z518C with a 200-horsepower Evinrude or Mercury outboard motor.

In just three tournaments, the man known by many competitors as “Little Joe” racked up more than $160,000 in earnings, including two new boats.

“I am on cloud nine right now,” said Joe. “…to get the win by just one ounce, wow! I am absolutely blessed – God is good,” Joe will now begin preparations for the Rayovac FLW Series Championship, held in just two weeks on the Ohio River in Paducah, Kentucky.

Joe Uribe Jr. Wins FLW Lake Havasu Rayovac Series!

February 2015

Joe Uribe Jr. won the first-place trophy in the FLW Lake Havasu Rayovac Western Bass-Fishing Series held at Lake Havasu, Arizona, February 5-7, 2015. Bob Lewis Machine Company has sponsored Joe since 2010, and he often finishes near the top in these super-competitive events held all over the western United States. "This is one of my biggest accomplishments," says Joe of his latest victory in the Lake Havasu event. His total catch over three days was more than 67 pounds of bass – including a mammoth 26-07 stringer on the final day – blowing away his nearest competition by nearly 15 pounds. Joe turned pro back in 2003 and won the Western Outdoor News event that year.

Speaking about his Havasu victory, Joe explains: “This year, the fish were definitely in pre-spawn mode. They were moving up in waves and I could tell in the areas I was fishing, they were replenishing. The largemouth were waiting in the shallow grass beds. They were all super healthy fish." Everyone at Bob Lewis Machine Company is proud of Joe's latest accomplishment, and we wish him the best of luck in his upcoming competitions.
