i’m seaching the web for more details but for some reason i can’t find a real answer yet
most (all) articles speak about dust not chips.
When is a chip big enough to be a chip?
When i use a router the ‘dust’ size is smaller then average sawdust. So i’m wondering if i work to slow or need to lower the speed. Looks like I need to do some experiments this afternoon…
EDIT, higher speed made nice long blonde curls… and a little less dust, but still a lot of dust…
I managed to look to close and got a huge load of dust in my face… Don’t try this at home folks… It hurts like hell. I wear glasses so that saved me to some extend.
So learned 2 lessons working faster makes curls, and don’t look to close without safety glasses. Myth BUSTED Wood dust can hurt like hell
when it doesn’t turn into paste if water is added (as good a definition as any)

Yes, you should slow the rpnm of the router, try a single-flute bit, and try to
speed up the feed speed so that the router moves over the wood more.
you may also try taking deeper cuts.
the material being removed helps remove heat from the cut. dust doesn’t remove
much heat, so the bit gets hot (and dull) and the wood being cut gets burnt.
I will do more manual routing this is a great way to get a better feel for this.
The sled as a router table idea that @Dag83 mentioned (see link below) is a great addition to a maslow to do things that you cannot do on the maslow itself.
And it seems to be a good way to play with spindle speeds and manually get a feel for the feed speed. And actually see what you are doing…
I also do quite a bit of woodworking and was looking into dust fires or explosions. I can’t remember where, I think that it was something about nerd woodworking or something like that, he discussed how much dust you need to cause an explosion and it was something like a 1/2 a board foot a minute. Like others have said PVD is an excellent insulation material so you would be hard-pressed to have an explosion with any home woodworking. If it truly was possible there would be a whole lot of shop vacuums exploding when cleaning up.
Hello, you have a laser cutter in your Maslow ?, you can put pictures so that
can we see it? also from the dust extractor <<
I work with many CNC machines. I have laser cutters. I don’t currently have a laser on the Maslow but I have thought about it. I don’t have a dust collector. I use the Maslow outside and don’t need to collect the dust.

Trabajo con muchas máquinas CNC. Tengo cortadores láser. Actualmente no tengo un láser en el Maslow, pero lo he pensado. No tengo un colector de polvo. Uso el Maslow afuera y no necesito recoger el polvo.
A simple idea, better safe than sorry, My shop and tools cost me a lot of money, so if there is potential for a problem like a fire or explosion, proven or otherwise, I will take the time to neutralize that potential to the best of my abilities. It doesn’t cost much or take too long.
The definitive article on home dust collection is below. The wrap it with wire method doesn’t allow fow PVC being a good insulator so while the wires will drain off some charge the areas between them will be unaffected, plus de-staticing the outside doesn’t affect the inside (where the dust is). If you don’t provide interconnects between the inside and outside wires you get a difference in potential between the two, and the inner wires and the high velocity chunkies can cause problems with each other.
However, ground wires on the outside will only hurt your pocketbook and spare time so if they make you feel better…
If I was that worried I’d ask around at my closest HVAC dealers for round metal ducting and fittings, they have sprial reinforced ducting around here in Mooseville so any reasonsbly sized metropolis should have it in abundance. Might anyway, just because I think it looks cool, although the esthetics of a moose might be suspect
I’m starting to not believe in home shops blowing up, everyone read somewhere that it happened to someone somewhere sometime, but i haven’t found a first hand record of it anywhere.
Kudos to Mr. Cole for his extensive research and numerous references. It’s dry, and academic, but it’s the best source of knowledge on the topic that I’ve been able to find.
Given the number of places that are selling PVC dust tubes (including
whole-house central vaccum systems), imagine the liability if these things
blowing up was really a thing.
I believe that is is possible, creating the perfect conditions.
It might be as unlikely as being hit by lightning, but depending on materials, dust (particle size), glues evaporating at what temperature, air (oxygen) level, rubbing surface (pvc, upvc, hdpe…etc). I am sure you can make it happen if you try hard enough. Sadly Mythbusters never answered, so they are not going to try it for us.
Possible, yes. Plausibility, however, depends on myriad factors.
See Rod Cole’s article titled “Grounding PVC and Other Dust Collection Myths.” at https://goo.gl/2t3XwG for an in-depth exploration of the issue.
Fortunately, the solution to any potential problem is quick, easy and affordable; involving several screws, some wire, and a few minutes of your time. Check out how Dave Stanton grounded his system here: https://youtu.be/XtkHzmXe4ZA
I can’t believe this thread is still going. Your dust collector is not going to explode. You have better odds of winning the lottery. PVC isn’t even a factor in the equation, the only place an explosion even has the possibility of happening is in the dust collection bin itself. The ducting to that bin doesn’t play a role. Use PVC all day people, almost everyone with a dust collection uses it and there are still zero documented cases of a dust collector blowing up due to ungrounded PVC piping connected to the dust collector.
