BUILT ON FIVE DECADES OF EXPERTISE

James Feltman started J&J Machine Shop in the basement of his house. He would work tireless hours after coming home from his day job when he realized that there was a need for higher quality machined parts.

1974

David Feltman, James’ son, took over the business and continued to grow it by offering welding services as well.

2002

David expanded into “J&J Nuclear Solutions” to offer products and services to the surrounding nuclear power plants.

2006

David was an operator on the new construction of the Invenergy Grand Ridge Wind Farm. Shortly after, he started making custom tooling and cranes for Invernegy.

2008

With a focus on renewable energy, Chad and Zac partnered with Dave to start "J&J Energy Solutions LLC"

 J&J launched its first Wind Field Service crew, with Chad, Zac, and Gia bringing the shop's machining and welding expertise directly up-tower.

The team filed its first patent for the Yaw Piston Pro-Cut (YPPC), an engineered tool that safely removes mushroomed or broken yaw pistons in three simple operations

2023

J&J filed a patent for its 500 Series Crane, a telescopic lifting solution built for up tower minor component exchanges.

That same year, the company filed a patent for the LSR Guardian, a CNC-machined lockout device that replaces unsafe zip-tie and wood-block methods to keep wind techs safe during maintenance.
