Positively Riveting: The Call is Coming from Inside the House

Why your rivet tool problem may not actually be a rivet tool problem.

Michelle, Positively Riveting

The first thing I notice in a plant usually isn’t visual.

It’s audible.

Compressed air is expensive, so when I walk through a facility and hear air hissing from tools that aren’t even being used, I already know something’s off. Maybe it’s carelessness. Maybe it’s exhaustion. Maybe people have just stopped hearing it because they’ve lived with it too long.

But usually, that noise tells me something important:

This plant is compensating for something.

And eventually, that “something” turns into:

“This tool is weak.”

“This brand is junk.”

“We need new tools.”

I hear it all the time.

And honestly, I understand why.

Because the thing in your hand gets blamed.

Not the compressor room.
Not the dryer.
Not the air lines overhead.
Not the contamination inside the system.

The tool.

It’s right there in your hand, so psychologically, that’s where everyone starts.

FACT

One of the biggest misconceptions in blind riveting is that the jaws simply clamp down on the mandrel and pull.

They don’t.

The jaws are actually sliding along the mandrel during the pull cycle. Metal sliding against metal every cycle. And anytime you have metal scraping against metal, you create debris.

That dark gray or black contamination people see inside mandrel catchers and tools?

A lot of times they assume it’s dirty air.

Sometimes it is.

A lot of times it’s actually debris created by the riveting process itself.

Maintenance guys know this because they’re the ones opening the tools and seeing it

packed inside the jaws and jaw cases.

Most other people never see the inside of these tools at all.

H2O

Then we add moisture to the equation.

This is usually the part where people look at me like I just said the word “unicorn.”

“Well, we have a dryer on the line.”

Okay.

But is it working?

I’ve opened tools where the hydraulic fluid looked like a chocolate milkshake exploded inside the tool. Milky fluid. Water contamination. Rust beginning inside components that should never see rust.

And the crazy part?

A lot of these plants already know they have compressor or air issues.

They know.

But somehow the conversation still becomes: “These tools must be defective.”

NOT SO FAST

You’re feeding contaminated air into a hydraulic-pneumatic system?

At some point, that damage catches up with you.

And when it does, the symptoms start looking very familiar.

Operators double-triggering tools.

People routinely cranking up air pressure.

Tools “feeling weak.”

Constant jaw changes.

Entire tool rooms full of backup rivet tools because nobody trusts the ones on the floor.

And here’s the part nobody wants to say out loud:

Every plant everywhere has normalized rivet tool problems.

Everywhere.

“Yeah, that tool jams.”

People say it like it’s weather. Like it’s just part of life. But most of the time, they’re

troubleshooting the thing in their hand while the real issue is somewhere upstream.

The call is coming from inside the house.

2 AM ROCKSTARS

I spend more time in tool rooms than conference rooms, so this part matters to me personally.

The maintenance guys are usually the ones getting blamed for all of this.

And honestly, I think part of the reason they get blamed is because they’re usually so good at everything else.

These are people rebuilding conveyors, crawling under forklifts, machining parts, keeping entire plants alive at 2 a.m.

So management looks at this little thousand-dollar rivet tool and thinks: “There’s no way THIS thing could be such a problem.”

But most of the time, maintenance isn’t failing.

They’re just looking at the wrong thing because nobody gave them the language or support to question the bigger system feeding the tool.

There’s a difference between:

“I missed something.”

And:

“I didn’t even know to look there.”

Those are two completely different things.

I GOT YOU

If you’re in maintenance and you’ve been fighting the same rivet tool problems over and over again, I want to say this clearly:

Your problems used to be my problems.

I know the dread of: “Not THIS thing again! What are those operators doing?!?”

I know what it feels like when the same tool keeps coming back to the tool room and everybody’s frustrated, exhausted, and looking for someone to blame.

Buying another tool is easy.

Blame is easy.

Frustration is everywhere.

But most of the time, you didn’t miss something.

You just didn’t realize the problem may not have started with the tool at all.

Because sometimes the issue was never the tool.

Sometimes the call was coming from inside the house the entire time.

Thank you to the team at IMS for hosting this mini-blog series and to everyone who read, shared, and engaged with it.

I love manufacturing.

Every day still feels like an episode of How It’s Made to me.

It’s been a pleasure sharing a small part of that world with you.
