RMJ Machine Worx Manufacturing BOWMAN rings since 2017! Custom piston rings,marine,vintage,anything with a piston ring

10/13/2026

We want to share something with our RMJ family before making any big changes.

RMJ Machine Worx has always been a small, family-run operation. What many people don't see is that Bjorn is working 80+ hours a week at his day job and then works 20+ hours a week at his RMJ job.

His day job pays the bills and requires a lot of his time and energy. Then, after work, weekends, and family time, he comes into the shop and makes rings.

We are incredibly proud of what RMJ has become. We know that the rings we make can be the difference between someone being able to rebuild an RC engine, restore a vintage engine, or finally get a long-awaited project running again.

But we've reached a point where we have to be honest with ourselves.

This pace isn't sustainable.

Bjorn needs time to rest. He needs time for his family. He needs time to simply enjoy life—and yes, he needs a little time to enjoy the hobbies and things that make him Bjorn.

We don't want to walk away from RMJ.

But we also can't continue operating exactly as we have been.

So we're taking some time to look at how RMJ can change into something that allows us to continue making the specialized rings you need without requiring Bjorn to work every available hour outside of his day job.

We may be making some changes to production schedules, lead times, order windows, and the types of work we accept.

Our goal isn't to make RMJ bigger. Our goal is to make RMJ sustainable.

We appreciate every person who has trusted us with an engine, recommended us to a friend, shared our posts, or simply followed along with what we're building.

We'll be sharing more about the next chapter soon.

Thank you for giving us the space to figure it out. ❤️

🎄 **RMJ Machine Worx Holiday Schedule — Plan Ahead!** 🎄

As we head into the holiday season, RMJ Machine Worx will be taking some well-deserved time off to **spend time with family, enjoy Thanksgiving and Christmas, and soak up all the holiday festivities.** ❤️

We will be **closed for Thanksgiving and Christmas and will remain closed until the new year.**

📅 **Our tentative holiday break will run from mid-November through mid-January.**
Exact closure and reopening dates will be announced once they are finalized.

Because RMJ is a small, two-person operation, this means **limited production time leading up to the holidays and no ring production during our holiday break.**

If you need rings before the holidays or early in the new year, **please plan ahead and place your order early!**

We appreciate every order, every customer, and all the support you’ve given our little family business this year. ❤️

🎅 **Order early. Plan ahead. And remember — family time comes first!**
