Father and son on the same shop floor in San Clemente, California. Machining since 2008 and in the family for generations, run the way a local shop should be: the people who quote your part program it, run it and inspect it.
We are not a brokerage. Every part is made here, on our machines, by us.
Not a startup either. No investors, no venture money. A machine shop that has been making parts since 2008.
One Off Parts was founded in 2008 by Patrick’s father. He got his start porting cylinder heads at a performance engine shop, earned a mechanical engineering degree, and went on to work in aerospace. A father of four who wanted to build something of his own, he started the shop in a friend’s hangar with a knee mill and a bandsaw. The knee mill became a 3-axis CNC knee mill, the first machinist was hired, the first Haas VF-2 arrived, and the work kept coming.
In 2020 the shop moved to San Clemente, California, and bought its first CNC lathe with a Y axis. In 2023 his son, Patrick McGowan, took over the business. Today the shop is 6 people under one roof, and the plan has not changed: a machine shop that stays in the family and keeps getting better at the work, with the tools of this century and the service of the last.
Any volume, quantity one to thousands, no minimums. Parts in as little as 2 days; standard turnaround 7 business days.
