Yipes!!! It is fortunate that you weren’t hurt. I also hope that you had your safety glasses on.

I actually had a full face shield that I use for my lathe… when I cut brass tiny chip go everywhere and goggles aren’t enough so I use a faceshield. Even though the flying brass bullet didn’t hit me I am really glad I had that on.

Look up. That piece could be imbedded in the ceiling.

When I cut small pieces of metal, I do the same thing with woodworking machinery that I do with metal working: use hold down clamps (like metal working strap clamps). Metal that is screwed down is happy metal. Then again, I learned that after a couple of times thinking I could secure it less, well, securely. I don’t like using the miter saw for metal anyway as the hook angle of my normal blade is too aggressive. I prefer a band saw or something that will cut a little more slowly.

The bandsaw makes so much sense… funny I never think of my bandsaw but I will from now on!!! I ended up using a crosscut sled on my table saw and holding the small piece down with a long piece of wood that I could apply pressure down and the fence on the sled took care of the back… worked perfectly but still the bandsaw would have been even better.

Glad you were not hurt. Unfortunately safety is learned by the mistakes we make.

Full face shield was a good choice.
I wear googles, (once in a while) and sometimes splinters/debris shoot up and hit my face.
Full shield that you can lift up when your not cutting is a good idea. I might get me one.
Did you find the pc yet? Could be lodged up in the guard between the blade??

Well I guess that’s one mistake you won’t make again….....!

Like I always say: “Any day with no projectiles flying through the shop is a good day!”

That piece of brass got REALLY HOT, melted the adhesive on the tape, and left for parts unknown. Next time: clamp the brass between 2 pieces of wood and clamp to the fence (or use the bandsaw).

I became a big fan of full face shields when using wire wheels in my die grinder and when cutting metal roofing with a circular saw. Also one time when gloves and long sleeves are indicated.

Yeah once I saw the footage I quickly realized that the brass got hot and melted the tape… still I should have had a back fence and something to hold down the brass… Just wasn’t thinking.

This is what I was working on… I will have a full write up when done but here is a preview… I’m restoring an old Stanley Spirit level and adding brass to the sides. The brass is still oversized in this picture and will get sanded down flush to the level.

Two thoughts: (a) A miter saw will launch anything that’s not backed up with the fence. Problem solved by mounting the metal to a larger piece of wood. I see you addressed that in the end notes. (b) Even a face shield will not save you if the Metal Missle hits you below the chin, and a piece of metal going that fast can cause serious damage. For instance, if it hit you in the neck—jugular vein or carotid artery. Knew of a WWer who died when a router bit exploded out of the table and punctured his femoral artery, bled out before his co-workers could save him.
