Catalytic converters are the coolest car parts that get no respect

The air in Detroit during the 1960s was so polluted that mothers were scared for their children to play outside. In certain places, you couldn’t see the sun at noon, and buildings had to be cleaned or repainted every six months. Some people wrote letters to...

Is perseverance in the service bay a feature or a bug?

I am a proficient mechanic. I have long said my proficiency comes partially from skill, but mostly I’ve achieved good results due to my perseverance. I am generally unwilling to toss in the towel on something until it works correctly. “Too stupid to know when to quit”...

Right to Repair gains momentum in Maine

The state motto of Maine, “Dirigo,” Latin for “I lead,” is being embraced by the members of the Maine Right to Repair Coalition who find themselves at the vanguard of a movement to ratify legislation that protects independent repair shops. Last February, a referendum...

Tool review: ICON 3/8” ratchet

About a year ago, I was reefing on some fastener, and my trusty old Armstrong ratchet let go and spun free. It did it again a few bolts later, and at that point I set the tool down before I got hurt. I had purchased a few 3/8” ratchets years earlier after some junkers...

PSA: Take a quick look at your punches and chisels (and be sure they’re ready for service)

by | Mar 28, 2023

Rebuilding ratchets, cleaning the welder tips and nozzles, and oiling air tools all fall under the umbrella of things we know we should do, but don’t until a job stops. Dressing chisels and punches, however, is a housekeeping task I’ve found not everyone knows they should be doing. In the spirit of safety: dress your punches and chisels!

Chisels and punches need maintenance. Your safety may depend on it.

Chisels and punches need maintenance. The business end of your chisels and taper punches can deform under use as you likely know. (You’re not beating the tar out of your pin punches, I would hope.) Chisels occasionally need their edges restored, and punches sometimes need to be cleaned up as well. I personally prefer a nice round, flat striking face on my punches, just like my tools had when they were new. Same goes for the chisels: a nice cutting edge simply makes them work better.

However, it’s the other end that gets dangerous. The end you beat on, I mean. The harder you hit it, the more it peens over—they “mushroom.” Those mushroomed sections, though, turn into a giant liability, because occasionally they break free. I’ve busted them myself when I was younger and dumber. Now I know better. I dress my tools—both ends.

Most of my friends and colleagues take this job on with a bench grinder. Most also keep a little cup of water handy so as to not ruin the temper of the tool. A flap disc or belt sander works well, too. I’ve used a file more than once; even that only takes a few swipes if you keep up with the work. I do the business end, then put a little taper on the striking end, and then back in the box they go, ready for work when I need them.

No matter how you do it, take a peek at your striking tools and make sure peepers and paint aren’t gonna get damaged. Don’t forget your splitting wedges at home if you burn wood—those are usually the worst offenders.
