The Redbarn workshop — long view of the shop floor and benches

I've been turning wood for forty-five years. Some of those years were spent learning. Most of them were spent practicing. In all that time I never once put a tool where a tool shouldn't go. I came home every night with ten fingers and no apologies.

A couple weeks ago, that changed.

The accident itself isn't much of a story. A cut I've made a thousand times. A piece of stock that should have been clamped a little better than it was. A half-second of not paying attention, which is all the shop has ever really needed to take something from you. When I pulled my hand back, the index finger was an inch shorter than it had been when I walked in that morning.

Just a trip to the ER, a few stitches, and a long quiet drive home.

What forty-five years teaches you

What a long stretch without an accident teaches you is not caution. It teaches you that caution isn't really necessary. You've done this a thousand times. You know what the tool is going to do. You know what the wood is going to do. And for a thousand and one cuts, you're right — until the one time you aren't.

I've never been the kind of guy who buys gadgets. If a tool still works, I don't replace it. I've got chisels older than some of the trucks parked in my driveway, and most of them still cut as well as anything you can order new. That philosophy served me well for four and a half decades. It also, it turns out, is exactly the philosophy that gets you hurt.

Selling the old saw

I put the table saw up on Facebook Marketplace two days after the accident. Sold it by the weekend. The fellow who came to pick it up had wanted one like it for years. I didn't mention what had happened to me on it. Didn't seem like the kind of thing to send a new owner home with.

The same afternoon, I drove down to Keim Lumber and bought a SawStop.

What a SawStop actually does

If you've never seen one, a SawStop looks like a normal cabinet saw — same fence, same blade, same everything. The difference is a small circuit that runs a tiny current through the blade. Human skin conducts electricity a lot better than wood does. When the blade touches flesh, the circuit detects the change and fires a brake cartridge into the blade. The blade stops completely in under five milliseconds. That's faster than you can flinch.

The downside is that when it fires, it sacrifices the brake cartridge and usually the blade, which together run about $150. So a finger-save costs $150. I know what my first finger cost, and it wasn't $150.

The lesson I didn't want to learn

Here's what I've been turning over since the accident. It's not that I was careless. Forty-five years of muscle memory doesn't come from being careless. It's that carefulness has a ceiling. You can be the best woodworker in Knox County and still have a bad second. The tool doesn't know how many years you've been at this. The tool just does what it's built to do, and what the old saw was built to do was cut.

A SawStop is built to do something different. It's built to assume that, eventually, even the best of us will have a bad second. And when that second comes, it's built to be faster than you are.

I should have owned one twenty years ago. I didn't, because I thought I'd earned the right not to need one. That was the mistake.

The saw is in the shop now, bolted to the floor, humming the same hum every saw has ever hummed. The finger is healing — a little shorter, a little stiffer, but still counting to ten if you're willing to accept a rounding error. I'm back at the lathe. Work is going again.

If anyone reading this has an old saw and no flesh-sensing brake on it, don't wait for your own story. Forty-five years of hindsight doesn't buy back the first inch.

That's why I listened.
