Mactech On-Site

The U.S. inland waterway system moves more than 600 million tons of cargo every year.

That’s roughly 17% of all intercity freight in America and over $158 billion worth of goods moving up and down our rivers.

That’s a ship ton of cargo.

We had a great time this week at the Inland Marine Expo catching up with longtime customers, meeting new faces, and having the conversations that matter most:

“What problems are keeping you up at night?”

Because that’s where the best solutions start.

Whether it’s line boring a rudder tube, machining a shaft, installing bearings, cutting steel, or finding a way to get a vessel back in service faster… we’re at our best when we’re listening first and solving second.

A special thank you to our friends at Thordon Bearings for another great show and for being a terrific partner in helping keep the inland marine industry moving.

To everyone who stopped by the booth, shared a story, asked a question, grabbed a hat, ate eleven Knudsen's Caramels because you can’t stop eating them, or just said hello… thank you.

Now it’s time to get back to work.

The cargo isn’t going to move itself.

We’ll continue to Make Ship Happen.

These photos are a good reminder that Mactech didn’t start with giant facilities, polished marketing videos, or fancy software.

It started with machinists figuring it out in the field and a roof over our heads to make some damn fine equipment.

A lot has changed since then. We’ve outgrown buildings, expanded capabilities, and added some incredible people along the way.

But the mentality is still the same:

Show up.
Solve problems.
Do GREAT work.
Take pride in it.

And honestly… some of the old-school setups these guys pulled off still make you stop and say:

“Yeah… that’s pretty badass.”

Proud of where we came from.
Even prouder of the people who built it.

Banana for scale just doesn’t work when the things you cut are this big. 🍌

These cuts were made with one of Mactech Offshore’s inline diamond wire saws… designed for big diameter cuts, while keeping setup efficient and footprints compact.

Proud of these guys and the work they do every day. And even more proud that THEY are proud of the work they do every day.

Cutting up big stuff safely and efficiently is what we do.

You know where to find us when you need us.

Today we remember. Forever we honor. 🇺🇸

Big pipe. No problem.

This cut involved a 112” OD pipe with a 3/4” wall… handled with one of our large inline diamond wire saw systems and a whole lot of planning before the cut ever started

What we appreciate about projects like this is that they remind people that “portable machining and cutting” isn’t just about the cut itself. It’s rigging. Access. Hydraulics. Alignment. Safety. Logistics. And a crew that can adapt when the real world inevitably laughs at the original plan.

Huge thanks to Reliant Recycling, LLC for trusting Mactech Offshore on this one. These guys do serious industrial recycling and demolition work across the Gulf South.

Can we all take a moment to appreciate how absurdly large a 120” inline diamond wire saw looks when it’s hanging from a crane in the middle of a plant?

You can rely on Reliant, and Reliant can rely on Mactech.

Weld it… machine it… make it right.

“Hope that cleans up.”

But hope isn’t a machining strategy.

This one needed the bore brought back to spec without removing the wellhead… welded in place, tight access, and a finish requirement that doesn’t leave much room for error.

So we set it up and machined it right where it sits.

Scope included:
• Boring from ~16.4" back out to final spec
• Holding a 125–250 finish through the bore
• Cleaning up the 45° bottom chamfer
• Working around a welded, non-removable assembly

All done with a portable boring and clamshell kit setup to face… dialed in, aligned, and executed in the field.

No shortcuts.
No second chances on alignment.

Just experienced machinists who know how to take something rough… and bring it back right.

The difference between “looks good” and “is right” lives in that last few thousandths.

Proud of this crew.

“Thank you to the craftsmen that continue to build this great nation.

May God bless you.

May God bless this ship.

And may God bless the United States of America.

While the steel is new… her name carries a great legacy.”

The US Navy Commissioned the USS Cleveland (LCS31) today in Cleveland, Ohio.

Proud to play part.

Make Ship Happen.

Need gear that shows up and works just like you do?

We build field machining tools that don’t flinch. No fluff. No lag. Just the equipment you need to cut, bore or mill… fast.

Our crew’s been in the field. We pack the boxes like we’re setting up the job for ourselves. If something goes sideways, we’ll pick up the phone. And as the customer, you’re at the center of our vision.

That’s what makes us the industry leader in on-site field machining solutions.

Don’t waste time waiting on vendors who don’t get it.

Up your game with Mactech. We’re ready when you are.

Sometimes the prettiest work happens in the ugliest places.

Dark. Wet. Tight access.

Doesn’t matter.

Mactech techs and equipment are here to get it done.

The reality is it takes patience, precision, planning, and operators who know how to adapt when conditions aren’t ideal.

Hard work.
Welcome challenges.
