Episode 56 – Woodworkers Safety Week Part 1
This 3rd annual Wood Workers Safety Week was organized for the community by the ubiquitous Marc ‘The Wood Whisperer’ Spagnuolo.
What I want to actually show you all today are the dangers of wearing baggy or loose clothing while operating a table saw. I realized that this would be a great subject while filming the next video that will come out later this week.
So, here we have a dummy with a single arm that should be a good representation of a left arm too close to the saw blade while wearing a baggy long-sleeved shirt. Yes I understand that the dummy is mostly positioned in front of the blade, but this could also happen with a right arm too. Just watch…
I’m showing the ‘naked’ dummy so you know how solid the structure is. A human would be constantly moving, while this dummy is solidly constructed and won’t move unless about 100 pounds of force push or pull it.
You might be able to make out that the cuff of the sleeve is already caught in a tooth of the blade. This is for our safety. If I were to pull the sleeve into an already spinning blade, the results would be very unpredictable. Here, we’ll start the blade with the shirt already caught in it.
Make him a little more human with a hat … and a face… And, let’s go.
OK, let’s look at what happened. In two frames of this film, the blade tore the cuff of the sleeve down into the saw. A third frame, and enough of the shirt was grabbed to lift off the zero clearance insert and destroy it. 4 more frames and the saw blade is so caught up with the shirt that it won’t turn anymore. So, that equates to 7 1/100ths of a second to destroy a shirt, a zero clearance insert, and possibly your arm.
Regardless of my initial observations, my zero clearance insert was not the only thing damaged. While removing the shirt from the blade I noticed the shirt shoulder had been ripped by the wooden arm’s sharp rear corners. I’ll show this later.
Let’s do another run with no insert.
This time, with no insert, the shirt was pulled in even further and almost completely around the blade. Let’s look at the aftermath.
A length of shirt about equal to my entire forearm was pulled down to where the dummy’s ‘hand’ was. Meaning, an entire forearm could have been damaged in this kind of an accident. I totally do not advise sawing without a zero clearance insert if this is the case. And, I think I’m making my next one out of hardwood instead of hardboard…
Joey, as my kids named the dummy, doesn’t look too happy here, huh?
Here’s that shot of the shirt ripped off the shoulder. And this was a pretty tough shirt to begin with…
Let’s gear up for a final test.
This time I moved the arm closer to the blade and stapled the shirt to the arm. I originally intended for the wooden arm to fall into the blade for the extra gore factor, so here I’m trying my hardest to get this to happen.
OK, looks like Joey’s ready…
OK, so no wooden arm or hand splinters flying, but still a good example of how fast an accident can ruin your day.
This split in the wood is not from the blade hitting it. The arm was made up of 2 3/8” strips of lyptus screwed together.
Here you can see that my once nice-looking shop shirt is trashed. And so is Joey…
I want to thank my kids for help with this demo and to my baby for napping long enough for us to set up and shoot it.
Stay tuned for my second video later this week.
