What router vacuum should I use?

Clever guy, and entertaining to watch - always good to see amazing things being created in less than ideal spaces, more like the world most of us inhabit.

Is that the vacuum he built where the blades went flying off, or the revised version :slight_smile:
I know he has a version that he’s not recommending…

He didnt mention that in the video!

Yeah if you watch some of his later dust collection videos, he’s using a 3-phase motor and a much larger impeller. The first version of that larger dust collector came apart and he re-made the impeller for it.

I can’t hardly stand to watch the video where he moves the dust collector to the corner of his shop. He’s talking about how much noise it makes from the vibration and then misses an opportunity to mount it to the concrete wall and instead hangs it on a 2x4 partition wall. :roll_eyes:

Anyway, the impeller build video actually has me pretty excited to get my Maslow working. I got a 5hp (220v) motor from a friend in the HVAC business and I’m itching to try out an idea I have for a dust collector in my shop.

how do you have it connected to the ridgid router?

i have not been able to find a hose adapter that goes from the 4"
on the dust collector to the 1-1/4" router.

thanks!

Here’s a picture from a previous discussion.

This one is much cheaper but not sure if it fits exactly to what you need: POWERTEC 70136 4-Inch to 2-1/2-Inch Cone Reducer

thanks. i also have one on order from harbor freight which arrived early
so i think we’ll go with that.

There is a big difference between how a dust collector and a vacuum work. You will not get hardly any flow when you neck down a dust collector to a 1 1/4" for the router. I would be surprised if you will get enough flow to make it worth the trouble.

didn’t @bar say he used the harbor freight dust collector? that’s why i got it.

I do and I it works great. I get almost no sawdust on the floor at the end of the day. I agree that duct collectors generally want to run in larger pipes but it still works well and the bag doesn’t get clogged as quickly as my shopvac and the dust collector is much quieter

Which one are you using?

I use this one:

I have the similar red one, with a trash can lid style separator, on a 16" wood lathe. I keep meaning to replace the 30 micron bag with a better one, but I try to wet sand with that orange flavored degreaser to keep the dust down.

Dust collectors are high volume low pressure to suck in fine dust and the flow rate drops off quickly with restrictions, plus the debris usually goes through the impellor to the filter. Shop vacs are low(er) volume but handle a higher static pressure with less of a dropoff and are made to handle the chunkies, with the air going through a filter before it hits the fan. With that big an impeller and horsepower the HF should have a lot of margin

Yeah, one tool on a DC that large, even with a lot of restrictions is still going to build a ton of vacuum. Plenty for one short run of hose and one tool.

Reviving and old thread because I couldn’t find the answer…

@bar, how are you adapting from the 4-inch inlet to router outlet? Do you convert “up” from a smaller hose to 4-inches at the dust collector or do you run a 4-inch hose and then closer to the router convert “down” to a smaller hose?

I ran a 2.5 inch hose and then converted down with a custom off center adapter which you can get the files for here:
