I got a hard lesson delivered today while starting a project in the garage this afternoon. I’ll lead in with saying that I’m ok (and will heal up fine in a week or so); only a bit rattled. Let me start with where my head was (and shouldn’t have been) that got me here.
I’ve had on my “To Do” list for 2019 to learn how to make box joints. Well, here we are into December and I’ve not even tried it. I had wanted to spend last Saturday working on it, but I let the weekend get away with me with Thanksgiving and Christmas decorations (which are fine and I was glad to get the time I had with all my family). This evening, I had a Cub Scout event with my son in which I was responsible for bring some audio and video equipment (i.e., our home AV receiver, speakers, and disc player). That ended up taking a lot longer than I had anticipated. But I had an hour to spare so I figured I’d at least get a jump start on my box joint jig, knowing all day Sunday (tomorrow) is going to be busy with other things.
And it’s entirely worth underscoring here: this is all arbitrary pressure I’ve put on myself. Absolutely no one else cares if I figure out how to make box joints ever, let alone today or even this year. But I had convinced myself that I needed to rush through the hour to get the table saw jig set up.
I picked out my backing board and was looking for a piece of scrap that approximately the same thickness as my table saw blade kerf (simply put, that’s the width of the cut that the table saw makes and is fractionally wider than the blade itself). My initial plastic piece for the jig ended up a big loose the backing board, so I wanted to quickly try a different approach. Mind you, the piece I’m trying to cut is less than a 1/4″ thick. So I figured, why not start with a thin off cut and just sand it down to the necessary thickness?
My power sander is a combination of a belt sander and 6″ disc sander. The disc of course will put a twist on any object pushed into it, so a firm grip and just being mindful of one side lifting and the other pushing down is important. I grabbed a long thing piece of scrap and tried sanding it on the disc, not thinking about where my hands would go if (when) it slipped out of my grip. I also failed to put on gloves. You certainly do not wear gloves with some power tools (anything with a circular spinning blade), but they are a good idea with a sander.
Within less than a second of me pushing the wood into the disc, it knocked it right out of my hand and left me pushing my fingers into the sanding disc. Now, in all the power tools I have, if I had to pick one that I was going to injure myself on, it would probably be the power sander. Blades, as you can imagine, can quickly cut into flesh and cause serious injury or death. I cannot imagine sustaining a life-threating injury on a small power sander like mine (though I’m not saying it’s impossible). But at 3600 rpm, 120 grit sandpaper can remove skin and nails quite rapidly. Certainly faster than my reaction time. Before I knew it, my unnecessary rush and lack of thinking about what I was doing caused me to injure my index and middle fingers on my left hand. My middle finger got the skin scraped badly but my index nail is about 1/4″ too short now. And boy howdy is that sensitive skin under there!
Again, it’s nothing serious. I was able to turn off the machine and immediately go treat it myself. My fingers are sore but the nail should grow back. Honestly, it’s the lesson I needed to learn. Power tools are not anything to be in a rush around. Every action with one requires complete focus and attention. I need to always think about how the tool could injure me based on the action the tool makes. Given that I was also using my band saw and table saw today (which, I do take less for granted, to be fair to myself), I’m fortunate that this is the injury I ended up with.
As my kids join me in the shop more, I’ve had to teach them lessons about safety. I’ve even had to warn my son about touching that very sanding disc until it comes to a complete stop (he thought he should stop it spinning one day after I’d killed the power). I even watching Stumpy Nubs’ video on recently injuring himself with an angle grinder and remarked on the need to pay attention when I’m working. I firmly believe that the number one most important piece of safety equipment is your brain. Too bad I failed to put that and my gloves on this afternoon. I’ll do my best to take that lesson to heart from now on.
