Lessons Learned #2: RIP shop vac

« Part 1: Getting started Part 2 of Lessons Learned series Part 3: Glue joint strength »

So the story goes like this: I’m in the garage minding my own business routing a groove down the center of some 1×2 poplar when I hear a loud pop and smoke starts billowing out of my shop vac/dust collector. I turn off the router, yank the shop vac cord out of the wall and get outside. It’s then that I remember that I unplugged the garage opener because I needed the outlet, so I had no good way of getting all the smoke out of the garage. So I hold my breath and plunge back into the garage, plug in the opener, and air out the space. Finally, I drag the smoking shop vac out to the patio and hose it down.

Let’s look at what went wrong here:
  • Underpowered shop vac used for dust collection. Perhaps little 5 gallon vacs from Target are not meant for woodworking. Go figure.
  • Dust collection bags. These things are actually fantastic, but apparently when you don’t empty them soon enough the motor gets unhappy and goes out in a blaze of glory.
  • Inadequate shop space. Probably time to get my basement space all ready to go, or at least add a few more outlets in the garage, so I don’t have to unplug the opener to plug things in (although it’s quite convenient, as the opener is right at about head level…)
  • I probably need to be more in tune with the sounds of my tools. Between my hearing protection and the sound of the router, I never even noticed the strained sounds I’m sure the shop vac was making.

On the plus side, I get a nice new (and bigger) shop vac now, and hopefully soon a small dust collection unit as well.

And of course, the aftermath:
Melted casing and burned up paper filter
Shop vac top

Dust collection bag stuffed full of dust and such
Shop vac bottom

And a good overview shot
RIP shop vac

Thanks for reading

Just to pass on an experience of mine, even though there is evident abuse here. I had a larger model shop vac with a motor failure. I called Shop Vac and they told me their motors don’t fail on the newer machines. So the guy says, give me your address and I’ll send you another, free.
So if this vac wasn’t an antique, you might try giving them a call. If it was, just keep it in mind for your new one.
You might also want to make some kind of mini chip catcher or cyclone to catch most of the dust. I use an Onieda Dust Deputy, but they do cost as much as two large shop vacs.

I think you need a bigger vacuum. Your photos and story have me rethinking my dust collection method: maybe it is time for me to upgrade…

Another one bites the dust! (Pun intended).

Steve, if you have the money, go straight for the small dust collection unit. You rightly said the Shop Vacs are not made for using as dust collectors. That said, I am still using a shop vac. When the right time comes though I am going to buy into something bigger.

Have fun shopping,

Question… could the fire have been started by vacuuming up sawdust that was so hot that the volume of air running through the shop vac caused it to catch fire? May need to call in the Fire Department CSI unit!!!

I just happen to be routing 1/4 inch tempered hardboard late yesterday and when I finished the cut, I looked up and the sawdust was on FIRE!!! Got the fire out and I waited a little while and used my 16 gallon shop vac to clean up the smokey dust. THEN I had a premonition and saw my shop vac catching fire late in the night and burning down the house. I emptied it right away.

Well, just a thought. I didn’t want us deriding the little Target shop vac if it wasn’t at fault. It is kinda cute.

Yeah, motthunter, MODERN ART!

Do what I did, make the base a mobile trash can, this way you can say you recycled….

Steve, as part of this lesson is your shop space now equipped with a fire extinguisher? Installed in an easily accessible location? As a firefighter, I would remind you to empty your shop vac every time you’ve finished using it for dust collection, since there could be smoldering embers you don’t see right away, and later that evening you get a nasty surprise.

I’ve got a large dust collection system in my workshop finally and I check it every night when I get ready to call it a day, no one wants that kinda of surprise.

Keep it SAFE and have a Happy Holiday!!

That’s actually a really good point, that I hadn’t really thought of. In the garage, my fire extinguisher was the hose, but I haven’t purchased one for the basement. I guess that’s now at the top of my list of things to buy.

After all, safety first.
