What does your dust collection hose management look like?

#1

My next addition is going to be some way to keep my vacuum hose wrangled up. Probably some kind of post with a hook or clamp up top.

Just wondering what solutions you guys found that work well.

#2

Mine is in a state of flux right now but some of the other guys have a better set up than I do. Hope they can help you out.

So this is a thing I did in OnShape

Its for a 2" hose. No idea if it will work at all.

I have a Rockler small tool dust right hose on mine. It has a rubber end that fits a variety of tools. I just have the excess hung with a bungie over the roof rafters.

I’m putting the finishing touches on my plans for my dust collection system. About to run some ducting and mount my collector to the wall and get a cyclone for it. Will build some blast gates and all that. Main problem with the CNC is the hose diameter. In order to pick up the fine dust you need to move a lot of CFM. Small hoses have high velocity but don’t move a lot of air. Since I am planning on a 6” main line, most people suggest when you drop to a tool but can’t keep it 6” at the machine it’s one to use like a 5” and 4” like at a table saw. For the CNC, it’s not likely I can use a bigger hose without significant redesign of the dust boot. So I am not sure the best way to go, other than I know I am sick of using my shop vac

You could bring an adapter up out of the dust boot and then add a length of flexible line to the Bigger extractor line and adapt it up to that. This would allow the same cfm from your extractor and still hook it up to the dust boot you have.

@mikecmp CFM and velocity go hand in hand. For a given CFM, say 1000cfm, the velocity will vary with the diameter of the duct; about 5000 feet per minute in a 6" duct and about 45800fpm in a 2" duct. It is the velocity that of the air that moves the dust/chips through the ducting. The same 1000cfm through a 2’ duct would only have a velocity of 380fpm and would not move material effeciently (which is the idea behind a cyclone; with the larger volume in the cyclone chamber, the air velocity is reduced and the larger chips fall out of the airstream). Higher velocities are required for vertical risers to push material up, so smaller diameter duct is required. Horizontal runs are bigger diameter to reduce static pressure drop (but that’s a different lesson). So, if you’re are using 6" horizontal mains, dropping partway down to your CNC with 4" or 3" duct and then 2" flexible hose to the dust shoe will provide plenty of velocity to move the waste material and lots of volume to gather finer particles from further away. No need to redesign.

On my home shop 2 HP dust collector, I have a flex 4" line that I can slip connect to each of my machines, one at a time. I’ve mounted a 4" elbow onto the bottom of my LongMill table that I can connect to the flex hose on my dust collector. On the other end of the elbow, I have an adapter that lets me use my shop vac hose to go from there to the dust shoe. I’ve modified the dust shoe to eliminate the adapter that came with it. Mine did not fit well and would not stay in place. I have the vac hose suspended from the ceiling on a bungee.

I have not been able to get the Long Mill to complete any jobs longer than 15 minutes, so I don’t have a lot of experience with this set up yet. I did get a job to go to 50 minutes yesterday before it froze and the dust collection was very good.

Hose management redneck style…

I like it, Lumpy! Mine is much the same, but my bungee is not near as nice a colour. :wink:

Lumpy: how are you supporting your monitor?

#11

@gwilki I’m using an old computer monitor wall mount. It swings back and forth and is working quite well.

#12

Tks, Lumpy. I’m using a laptop on an old keyboard “drawer” that I had kicking around. I may replace it with a tower, as I have spare monitors. Looking down onto the laptop monitor can be a bit of a pain.

#13

So, this is what I’ve been working on. Initial testing seems good. Time will tell.

Interesting. Is that a old chemistry holder/stand? or specific made for vac holding?

#15

It’s just a piece of 1/2 inch heavy wall swagelok tubing I pulled out of a dumpster and some brackets I made in onshape and printed up. The pieces holding the hose have captured nuts up against the tubing so I could have an effective setscrew. It took a couple iterations to get everything to fit.

For anyone curious, the onshape document is here: https://cad.onshape.com/documents/57648b7f221a8b14202c6da4/w/09ca17006a988771f02d3db7/e/6ef8f0a441b6df6b9b3ffa87

Nice! Will take a look at that David.

I think I will start a thread about blast gates - I just drew some up, then came across another design that I like much better but is not as efficient with material.

Mine is hillbilly. I half sliced a swimming pool noodle and fastened it to the edge of my table. It slides over that just fine. If you want the low cost solution this is it! :grinning:

Well, my little boom setup seems to work really well. At least for the few jobs I’ve done. If anyone needs help remixing it to work with more common/cheaper materials and a more common hose size that would be pretty easy to do. I’m thinking 3/4 EMT conduit would probably be ideal, cheap and readily available… I’m not sure about more common hose dimensions… I know mine’s not really standard.

Anyway, if anyone wants to provide some dimensions that would work with more common setups, I’ll put it up on thingiverse. I’ve had a lot of downloads on it already with my weird setup, so I imagine there’s a need for it.
