The darn sawdust…
It’s one of the biggest downsides of using a circular saw (or any saw, really) – the dust gets everywhere, and it’s pretty difficult to manage.
You do have a few options for circular saw dust collection, but there’s pretty significant downsides to each.
The key thing here is that effective dust management with most types of power saws takes a lot of effort.
The key word there is “effective” – it’s easy to do some poor dust management…
But it’s just that – poor. Which basically means you’ll still be left with a bunch of dust all over your floor.
The options are:
- Shop vacs or dust bags connected to a saws dust port.
- Custom built hoods that cover your whole saw.
The dust port option
Many circular saws have standard features and lot of them also have dust ports and they’re pretty easy to spot.
They’re basically a little port attached behind the blade, which allows you to attach a shop vac and suck dust through the port as you make a cut with the saw.
In theory, these are great.
But in reality for most circular saws through the years, the dust part has been totally useless.
It usually proves so ineffective at collecting dust, that it’s better to just not bother using it at all.
Nowadays on modern circular saws, especially the best circular saws out there, the dust collection port is a little more effective… But basically, you’re still going to end up with tons of dust all over the place.
This is the “poor” dust collection method I mentioned above.
You can be sure it’ll collect some dust… but far from all.
The custom option
Alright, now this is where we’re going to get serious with this dust collection stuff.
The custom option is for when you’re just done with this dust nonsense.
You’ve had enough, and it’s time to deal with this once and for all.
It’s going to require building a hood that covers your whole saw, so there’s gonna be some work involved. And because every saw is a slightly different size, you’ll most likely have to do this work yourself.
It’s actually a pretty interesting project in its own right.
But the point is – this probably isn’t the option for you, unless you’re really sick of dust and want to put time into building a solution.
The upside is that once you build a good hud, it’ll work. It’ll be an effective dust management solution and you’ll have very little cleanup after cuts.
You’ll find plenty of ideas, styles, and tutorials for custom dust collection huds online – For an experienced builder, it probably won’t be a huge job.
There’s a lot of things to consider, though.
You’ll want the hood to have a good seal all around the saw to catch as much dust as possible, but you also need to leave space so you can still hold and operate the saw.
You also want to design your hood carefully, and try to leave yourself an open sightline to your cutting line. A hood getting in the way of your blade view would really hamper the saws effectiveness and pull down your accuracy.
Also, keep in mind that you’ll need a port to attach your shop vac – or, perhaps you can build your hood around the existing dust port in some saws.
Circular saw dust collection is a pain in the ass.
The choice is to put up with dust all over your floor, or put significant effort into a custom solution… either choice has a downside.
If you’re sick of the cleanup after every use, then go ahead and build a custom solution.
I just put up with the dust. Most other tools also make a mess with dust… So if you’re not going to build a custom solution for all of them, then why build a solution for any single one?
The way I see it, you’re going to be cleaning up at least some dust no matter what you do… might as well just deal with it and keep on truckin’.
