Picture of CNC router dust boot
I have a CNC for a while now, and it's totally awesome.
However one downside is the huge amounts of dust that fly around whenever I make a part.
(And the fact that I have to chase my mill bits all over the project, which gets boring on longer runs)

For a while now I've been looking around at the options here on instructables, looked on the internet, checked out all the stores, and so on. All in all I really wasn't getting anywhere

Since I couldn't find what I wanted/needed I made a decision..
I've got a CNC, just DIY it! I also wanted to share with you my train of thought and general work-path.
As in my previous 'ible I will not be giving an specific parts list, since your CNC will probably differ from mine.
I will be, hopefully, giving you some food for thought when you set out to design your own dust boot.

Total cost is up and arround 10-20 $/€, depending on how cheap you can source some of the stuff.

My dust boot will be connecting to a dust extractor which I'm currently making according to another instructable:

For the tools you will need:
- CNC
- Hot glue gun
- Plumbing plier
- Wire cutters
- Your preferred design software (I use Solidworks and Solidcam)

For the Materials:
- Air hoses outer diameter should be equal to the inner diameter of the large diameter drainpipe.
  I sourced mine from a DIY store that sold them for use in garden ponds. They carried different sizes.
- Hose connector coupling of the same diameter as the air hose (3-way)
- 2 pieces (or 1 large piece) of lexan
- 2 drainpipes, where the outer diameter of the smaller is the inner diameter of the larger (give or take a bit)
- Letterbox wind stopper (the brush kind)

superglue + plexiglass = gooey mess + poisonous fumes

That's interesting, because, if it is the stuff I think it is (it isn't shown in any of your images), I tried to use it as a cheap(er) source of hose to circumvent the absolutely outrageous prices of real vacuum hose. and I found that it emitted a piercingly loud high pitched scream when air passed through it. You don't experience this?

I think that you have a ridge somewhere in the hose or maybe too small a diameter hose.
Get a larger diameter and you ought to be fine.

You're right on the.picture, totally forgot!
I will add one later today.

A long, long time ago....
In a country far far away....
I totally neglected to update this instructable with some action video..

Updating the instructable to include a video, as I type.
I will also add a picture of the hose in question, in reply to "temper"

Clever!

This inspires me to seek an easy way to keep my workshop clean when turning wood. Maybe a well located deflector will do the miracle...

I don't have any experience on a lathe, but when.I've got some time I will post my.ponderings!
