Custom machining, welding and repair
Almost everything we do is custom: made or repaired to fit your part, your equipment and your deadline. We machine and weld under one roof, so we can build up a worn part, machine it back to size and get it back in service without sending it to two different shops.

Customized to your job
Every part and repair is customized to your equipment, your material and your timeline. If it doesn't exist, we'll make it.

You talk to the people who do the work. Straight answers, honest advice, and a shop that has been earning repeat customers since 1984.
Big equipment? We bring the shop to you.
Tearing out a gearbox, frame or shaft and hauling it across town can cost days. In many cases it's faster and cheaper to repair it in place. We bring portable boring, milling, turning and welding equipment to your plant, dock, mine or job site, and we design and build our own tooling for unusual jobs.

Industrial equipment and small projects alike
For industrial companies, we revitalize old and aging machines and equipment so they keep running for years to come: mines, railroads, ships and docks, contractors and the plants around the Twin Ports.
For individuals, we take on small projects and repairs. No job is too small. We've served the general public since day one, and we take on work from customers across the country who ship us their parts.
Family-run since 1984
Bob Cragin opened the shop in 1984, after the machine shop where he worked closed. Customers who knew his work brought him their jobs, and the shop grew from there, adding machines and expanding the building along the way.
Four decades later Bob still runs the shop, now alongside his son Allen. We still take on the hard, one-of-a-kind jobs, and many of our customers have become friends.
“Founded by Bob Cragin in 1984 and run today by Bob and his son Allen, Cragin Machine Shop carries on a tradition of dedication and quality service to our local community and beyond. Far beyond.”

Common questions
Do you do on-site machining and welding?
Yes. We bring portable boring, milling, turning and welding equipment to your plant, dock, mine or job site. In many cases repairing a part in place is faster and cheaper than tearing it out and hauling it in. Call to talk through the job.
Can you make a replacement part without a drawing?
Yes. Bring or ship us the broken or worn part, or a sample, and we will measure it and make a new one. We can also draw up 2D and 3D prints for you.
What materials do you machine?
Steel, steel alloys, stainless steel, aluminum, brass, titanium and plastics are most of what we see. If you are not sure about your material, ask us.
Do you take small jobs and individual customers?
Yes. We work with individuals on small projects and repairs, just as we work with industrial companies to revitalize old and aging machines and equipment. Since 1984 we have served both, from a single repair to production parts.
What are your hours, and where are you located?
We are open Monday through Friday, 8 AM to 5 PM, at 2106 Central Ave, Superior, WI 54880. We serve Superior, Duluth and the Twin Ports, and customers farther away who ship parts to us.
