Quick video of my simple MS dust collection. The constant cough that I had after making a lot of cuts on the MS was what drove me to get a DC in the first place. After experimenting with a variety of hoods and DC setups and I found that the hood design doesn’t really matter too much if you have a powerful DC. As you can see in the video, the particle count only increases from 190 to 520 after a series of cuts. Still need to make a few adjustments to the design (want to improve the collection of dust thrown to the back of the hood) but overall the current setup does what I want it to; keeps the dust from being thrown into the shop air.

The dust collection looks like it does a very good job but the background music is very annoying. had to turn my sound off.
I’ve built several dust collection systems for my miter saws before settling on one i really am happy using. It hooks up to my main dust collector in addition to my shop vac. Dust collection is something that is always can be tweaked and improved.

I liked your box design set up so it can be the target from your Makita saw dust port,

So do you get better performance with the hose or the hood? I don’t see you draw a conclusion -

Could you port the MS directly into your system and then move the general suction to the bottom of your hood? I am considering a similar build.

Good luck!

The particle count with the hood after cutting was ~580, after the same amount of cuts with the shop vac hooked up, the particle count was 8000… so the hood was massively more effective at keeping dust from being thrown into the air.

I’ve thought about porting the MS into my DC system; I find though that having a hose attached to the MS port just makes it awkward to use, and I have to move the dust hood back which reduces the effectiveness of the large 6” DC opening in the hood. Overall, having a suction opening under the MS or at the back is less effective; the majority of the dust from the MS is thrown back at an upward angle.

Very interesting. I see why hoods are more popular than just hooking up a hose. Would you ever consider doing both?

I find the hose is awkward and interferes with the position of the dust hood; as well, the hood appears to capture most of the dust without a hose attached. It helps to have a 5hp DC system!
