I have a dust collector that I use to collect dust and chips from most of my woodworking tools including my table saw, jointer, planer, band saw, router table and all of my sanders. Lately I have been clamping the 4" collector hose to the table of my scroll saw. So I decided to do something more permanently. I used two 2 1/2" hoses with fitting to mount above and below the table: http://www.woodcraft.com/Product/2021187/28973/212-Dust-Source-Rigid-Flex-Set.aspx. I used zip ties to mount the top hose to the upper arm and the the 4" hose to the leg of the stand. The hose does not add much weight to the upper arm.
I haven't given it a thorough workout yet, but it seams to do very well so far!

Wow! I guess there's no more dust when you're working!!!
-
nice. That should catch a lot of dust. You have a professional shop vac system I guess?
At this point we should mention to NOT use drain tubes. Those are loading static energy through the dust and are therefor able to ignite the dust and burn the complete house.

Not true Torsten. There are no documented cases of static electricity igniting saw dust in a home or professional shop. Here in the U.S it is common to use PVC or ABS plastic tubes in home shops. If it is a concern it is easy to ground the system with copper wire.
I have been using my dust collector with plastic tubing for over ten years without a problem!

Wow, those are bright...do they allow you to work with the lights off? ;D ::)
Seriously it looks like you can capture a lot of your dust. Where is your vac at and how loud is it? Let us know how it does. I'm curious on how the lower port works or if you'll have to add a smaller fitting?
Thanks for the views.

Karl, I don't use a shop vac. I use a dedicated dust collector: http://www.pennstateind.com/store/DC1BXL-1M.html. A dust collector is designed to attach to large woodworking machines. They are designed for high volume not high velocity like a shop vac, so the larger the hose, the better. That is why I am using two 2 1/2" hoses. Mine is at least half as loud as a standard shop vac. I use a home built first stage separator that collects 95% of the debris. I only have to empty the lower bag about once a year.

Hey Dan, I made almost the same setup. Just a suggestion, the 2 1/2" hose with fitting below the table, if you mount it directly below the table angle adjustment knob attaching it between the two front legs (give enough room to adjust the table when needed) the dust and debris will fall down into the fitting, taking advantage of gravity. That is the way I have mine mounted and it works great. Very little if any dust and debris on the floor or the saw. 8)

I went all out for my dust collection. It's called a Broom
-
My "Dust Collection System"....
Sweep Floor, pick up dust and put in trash bag.
Open Garage Door.
Turn on 30" Fan on High Speed and point toward door.
Hook up leaf blower and remove dust, venting toward exterior.
Turn off Blower and Fan.
Close garage door.
Go get libation.
May not be the most efficient or Best system but it sure is easy and CHEAP!

I like your system best GB, I might just have to adopt it ;D
-
I like that Gb, It is a lot like mine except I use Vacuums. They are not as loud as my dust collector and I do have them set as far from the scrollsaw as I can get them. I can't hear them over the sound of the scrollsaw. The main thing is the dust is not flying around the air and attaching itself to clothes, shelves, lungs etc. Great job. Good Luck :)
-
Dan, It does not mean that all plastic-pipes are not good. There are also some materials, that work fine and do not have static charge. Also are some systems build on a high air velocity, that prevents such effects.
In Germany are PVC-Pipes in dust collection systems not allowed.
I know about at least 2 wood shops that have definitely burned down due to static charge in such pipes.
You should also be able to feel that static charge on such pipes by just touching them.

If you are worried about the static you can ground the pipes by running wire through them

Why? not a lot of dust to require that much over the top gear ?

Why? not a lot of dust to require that much over the top gear ?
when you cut as much as I do, there is a mountain of dust under my saw. There is also a lot of airborne dust. I am not so concerned about the dust that falls to the bottom of the saw or floor. As GB said, it is easy to sweep up and vac with a shop vac. I am more concerned with the airborne dust. Have you ever blown your nose after cutting for several hours? A lot of crap comes out! Can you imagine what your lungs take in? Did you know that wood dust is a carcinogen? That means that it can cause cancer! I personally know of two woodworkers that died of lung cancer. They did not smoke!
So, Thats why!

Adequate dust collection is a must in any shop to protect your health. Every dollar spent will be well worth it in the long run. There are several inexpensive ways that work very well. One is an AC filter strapped to to a box fan. Also the fan/motor from a clothes dryer work well and can be vented to the outside so no filter is needed. :)

This has been a problem for many years and if someone had a good price extraction system folks would buy it but they tend to cater for larger production businesses who can afford them not the solo craftsperson.

Thanks Dgman, I built one just like it and man, does it help! Between the dust collector and the air filter above the scrollsaw, and mask, I can breath after a long day of scrolling. Before I would cough and hack all night. Thanks again!!!
-
Good to hear it's working for you Raptor! I gave mine a good workout today, And it did a great job!
-
Thanks for the ideas!! I have been thinking/looking for some ideas for a similar set up. I have been doing the good ol' broom and dust pan method but now that I am doing a lot more cutting, I need to set up something. I just recently made a set up for my lathe and it works great and I made my own "cyclone" separator for my shop vac. I needs a little tweaking but it works!

It does add up after a while, and it's so fine it gets everywhere, any shelves, wet paint, in your lungs, in your eyes, just to name a few, and some woods are toxic so you don't want them in your body! Those fine particles drift as easily as pollen which is probably the number one cause of allergies so I think they would add to the discomfort.

Hey Gabby, did you get the beast running (your computer)? If so you up kind of later for a older fella, ain't ya.

Chuck I'm a certified NIGHT OWL I'm up as a regular thing till 2 or 3 and some times even later.
I've always liked the night time when everyone else is asleep, no interruptions and it's quiet. I've worked nights for a good portion of my life and my last job was nights, so when I was forced to quit working the clock still stayed on a night time schedule. The boss complaines about it all the time but I'm retired so I'll do it my way!

Note to self: don't cut puzzles and push the puzzle pieces toward the dust collector mounted to the table top. By the way, my dust collector doesn't have a chip catcher on the side so a puzzle piece got caught in the collector fan. Unfortunately I can't use it cause it's mangled too bad.
I guess I need to install a chip catcher between the saw and the collector. Any ideas on how to do this?
-
some fence should do the trick. Mine has a bag for the dust. I accidentally vacuumed some drill bits some weeks ago - and found in the bag not only those, but also some screw bits and various other things I was missing.

Hey Chris, I have a homemade chip collector that I made several years ago. It uses a 30 gal. fiber drum. I used toilet flanges to mount the hoses to the top of the drum. You can find a parts kit here: http://www.ptreeusa.com/dusthose.htm. Here are some pic of mine.

Those lids do work nice. They create more of a vortex inside of the drum to allow for better chip fallout.
