The Pallet Nails That Kept Turning Up in Other People's Gardens

How We Ended Up Chipping Pallets

My partner Dale and I did not set out to make mulch. We set out to stop paying for it. We had four acres outside Gympie, a vegetable patch that drank water like a teenager drinks milk, and a neighbour who ran a freight depot and kept asking if anyone wanted his broken pallets. Dale borrowed a chipper from his cousin one long weekend in 2019, fed about forty pallets through it, and by Monday we had a mountain of pale, sweet smelling chip and a garden that held its moisture through a February that would have cooked it the year before.

Then people started asking. The woman who sells eggs at the end of our road wanted a trailer load. Her sister wanted two. A landscaper from Cooroy rang because he had seen the pile from the highway. Within eighteen months we had a second hand chipper of our own, a tipper truck with a dodgy clutch, a hand painted sign, and an arrangement with three depots that would rather give us their broken pallets than pay to have them dumped.

I kept the books and did the deliveries. Dale did the chipping. It was never going to make us rich, but it paid the rates and the vet bills, and I liked the feeling that something headed for landfill was ending up under somebody's tomatoes.

The Thing Nobody Mentions About Pallets

A pallet is mostly wood, and partly nails. That is the whole problem in one sentence, and it took me two years to really hear it.

We knew about the nails, of course. Dale would knock the obvious ones out, and after chipping I would drag a rake across the piles and pick out anything shiny. Every few weeks a customer would ring and mention a staple or a bent nail, and I would apologise, and we would both laugh about it, and nothing changed. I told myself it was part of the product. Rustic, I called it once, to a man in Tewantin, and I still go hot in the face remembering that.

The chipper knew better than I did. The blades needed sharpening more often than the manual said. Twice a nail jammed something and Dale spent an afternoon on his back underneath it, swearing at the sky. We wrote it off as wear and tear.

The Phone Call on a Sunday

It was a Sunday in late spring, the kind of morning when the whole valley smells of jasmine and cut grass. My phone rang while I was hanging washing. It was a young mum named Kirra who had bought a trailer load from us a fortnight earlier for her new garden beds in Gympie. Her son, five years old, had run across the beds barefoot chasing their dog and stepped straight onto a pallet nail standing upright in the chip.

She was not shouting. That was almost worse. She was very calm, the way people are when they have spent the night at a hospital. He needed a tetanus shot and three stitches, and she had spent an hour on her knees with a torch sifting the mulch with her fingers. She had found eleven more nails and a handful of staples.

I drove over that afternoon with a bag of oranges from our tree and absolutely no idea what to say. The boy, Jesse, showed me his bandage with great pride. Kirra showed me a jam jar with the nails in it. She had cleaned them and lined them up by size, and that tidy little jar did something to me that no angry customer ever had.

I took all her mulch back. I raked out her beds myself and refilled them with bagged mulch I paid for at the hardware store. Then I drove home and sat in the truck in our driveway for a long time.

The Week the Chipper Died

As if the universe wanted to underline the point, the chipper threw a blade nine days later. Something hard went through the throat, there was a sound like a gunshot, and then a grinding that Dale said he could feel in his teeth. The repair quote came in at more than we had cleared in three months. When the mechanic pulled it apart he held up a chunk of steel strapping that had been folded into the timber of a pallet and missed by Dale, by me, and by the rake.

So that was where we were. A boy with stitches in his foot, a broken machine, and a business we had both started to love sitting on a pile of wood that we could no longer pretend was safe.

Dale wanted to quit. I wanted to quit too, for about a day. Then I remembered Kirra's jar and decided I owed it to her to at least find out if this was a problem people had already solved.

Learning That Bigger Operations Had Solved This Decades Ago

Of course they had. Every timber recycler, every quarry, every mine and every grain mill deals with stray metal in a moving stream of material. I just had never thought of our little operation as belonging to that world.

I spent a few evenings reading at the kitchen table with a cup of tea going cold beside me. I learned that the whole field has a vocabulary. Tramp metal, which is what they call the stray bits that do not belong. Overband magnets that hang above a belt. Drum magnets and pulleys. I found myself on a supplier's page reading about Magnetic separators and realising, a little embarrassed, that our problem was so ordinary in industry that people manufacture whole families of equipment for it.

Some of it was far beyond us. Some of it was not. What mattered most was that I finally understood the principle. You do not rely on a person with a rake. You put the material on something that moves, and you let the magnet do the picking while the stream goes past, every single time, without getting tired or distracted on a hot afternoon.

I also learned that magnets only catch what is magnetic. Some of the bands and fittings on imported pallets are not, which is why bigger plants pair a magnet with a Conveyor metal detector that alarms or stops the belt when something metallic gets through. I read that paragraph three times. It was the first time in two years anyone had described exactly the gap we had been falling through.

What We Actually Changed

We did not turn into a factory. We are still two people on four acres with a dog called Biscuit and a truck that only starts if you talk nicely to it.

But we rebuilt the way the work flows. The pallets get stripped on a bench now, with a proper magnetic sweeper run over the ground at the end of each day. The chip comes off the machine onto a short secondhand belt Dale welded together from a conveyor he found on a farm clearance in Kilkivan. A magnet sits over that belt, and the first afternoon we ran it, I stood there and watched nails jump up out of the chip and cling to it like iron filings in a school science experiment. I actually laughed out loud. Dale looked at me like I had lost my mind.

The setup we ended up with is closer to a home made version of a Dry magnetic separator than anything I would call professional, and I am honest with every customer about that. I tell them how we screen it now and that I still ask them to wear shoes in fresh beds for the first few weeks, because I will never again promise that anything is perfect.

What I Carry With Me

The chipper got fixed. The blades last a lot longer now, which Dale says is the only part of this whole saga that pays for itself. Our orders dipped for a while after word got around about Jesse's foot, which was fair, and then slowly came back.

Kirra bought from us again the following autumn. She did not have to and I told her so. She said she wanted to see whether we had meant it. When I dropped off the load, Jesse ran out in a pair of bright green gumboots and asked if he could see the magnet. I showed him a photo on my phone of the nails stuck to it, and he studied it with the seriousness of a five year old who has a personal stake in the matter.

I still have that jam jar. Kirra gave it to me when I left her house that first Sunday, and I keep it on the windowsill above the office desk where I do the invoices. Some days it just looks like rubbish. Other days it reminds me that the difference between a business that is lucky and a business that is careful is usually one person getting hurt, and I would rather never learn that lesson twice.
