I have been trying to figure out a way to get the dust from under the scroll saw without a hose getting in the way. I really like this setup. Thanks Steve.

I like Steve's setup but I don't think you will ever clear all the dust from the top, as for under the saw, I set up a shop vac with the same idea as Steve and found it to noisy, ok ear protectors/muffs but I hate them.
I set up a small box under the saw to catch the dust and clean it at the end of the day, easy no expense.
But as for the top no answer yet, I'm broke and still thinking.
Just my 1.5 cents worth if it's worth that much. LOL.

Hmm, I just watched the video.
It would be nice to have a clean saw and wood shop at any time. But the noise!!!
No, that's to much to take for me. I think I'll leave it to my system - cut and as I get a break, clean the mess with the vac. There has always been dust and there will always be dust in the wood shop. Some things can not be changed.

I have a canister vacumn with a long hose attached to the funnel under my saw. Then I built a Box of 2 inch styrafoam that fits over it. It just needs a small hole inopen in back to be able to suck air in. I built this after talking to the vacumn guy. It really cuts down the noise. I have a three way plug in my foot switch and plug the vacumn into that. So when I am sawing I am vacumning. I also have the 20 fan rig.

Judy - you are just SO efficient! BUT why did you let my ides out of the bag?
Re-doing everything in the shop and that is part of my PLAN!!! Have a very small shop vac that I am building a box to 'cover' lined with styrofoam insulation and a vent tube running out the back with a couple pieces of discarded panty-hose as a filter. Took an old very large metal funnel and did some 'blacksmithing' to flatten and adjusting for clamps to fit the underside of my 788.

I use the blower an motor from a clothes dryer for my scroll saw dust collection. Quiet and no filters/bags. Blows out the side of my shop. :)

@ Russ
Can you provide us some pics?

Take a look at this if you use a small enough shop vac this may work for you as well..

After watching the 3 videos I am convinced that this guys set up is something good for any work shop that uses a shop vac. I shall start constructing my roll arould shop vac box soon. Might even connect the power cord to my foot switch and install Steves idea of the funnel under the table. Love this forum. Always learning something. Danny :+}

I did look at the video's to, great idea to reduce the noise.
my question is: isn't the vacuum getting to hot and therefor what is the risk on getting fire?

check that one out - looks nice too.

I did not watch Steve's dust collection video as I am already set up and although dust from scrolling is not that much in comparison with wood turning you still have a problem and it is vital that you should have some sort of collection system, this is for your own health and if you can not afford it don't make dust, the system I made for my saw cost me nothing apart from 1/2 hour of time, and all I use a is a domestic vac. that was given to me and an old heat transfer fan, think about it

@ Judy
Please show us some pictures of your setup. A simple setup is a fine thing a lot of people might be able to use.

Picture 1.....from left to right:
House vacume (very quite) goes to which ever sander I am using
Canister vac goes to the funnel under the saw Or can switch to disc/belt sander
20 inch fan with air filter on the right side of the saw.
Picture 2.....hose from canister vac to the saw
Picture 3....Something I created from a juice jug, doll stand and workout weight

Good Job Judy looks like you have it covered for sure....I have but one questions How big is that shop of yours? It looks like it is as long as a Trailor house. Being in Texas we have alot of those Hmmmmm I just may have to see if I can find a small that would make a nice shop Thanks for the Idea Judy.....lol

24 ft x 14 ft. It used to be my jester studio.
-
WOW!!!! can I move in with you? Lmao my shop is only a tiny square of what you have...
-
my question is: isn't the vacuum getting to hot and therefor what is the risk on getting fire?
I'm not sure but I belive that is the reasons for the baffle bottom and the air holes in the back he did say they 2" holes so with ample air flow I don't forsee a problem with over heating just MHO.

thanks Judy!
be patient with the vacuum cleaner, the filter will not keep the dust out of the engine.
There are quite some handymen out there, who had to become aware of their burning vacuum cleaner.
I bought an industrial vacuum cleaner, which is able to handle the dust. But that one is much more noisy.
I think I will try to produce such a cyclone extractor system as seen in the how-to @ instructables.com.
It's a combination of the cyclone-system and a low noise setup. Both something I'm looking forward to have - no noise and no filter paper.

Thanks for the reaction.
know that the holes are big enough for the airflow, but a 1500/2000 Watt engine produces also a lot of heat.
especially when the bag is almost full the engine has to work harder which increases the heat.
in the video the vacuum engine was on the top, so the heat is gathering/increasing in the top of the box.
I'm not a pro but as far as I know, when building electrical equipment in to a closed space overheating is a risk.
on top of that, you have dust, hot air and sparks from the carbon brushes in a closed box, could there be a small risk on "dust explosion"?
I don't know if this is a problem, might not be a problem at all.
I am precautious and curious to your opinions.
better safe then sorry is my motto. ;)

Thats a possibility Marcellarius.
Mounting a small fan inside the box might help with circulation thereby helping to keep dust from concentrating enough to catch fire from the brushes. But theres always the possibility of static electricity building up which can also ignite dust. Although I've never heard of it actually happening it is a possibility. Thats why alot of people ground their dust collection systems. Another thing to consider (according to my conversation with shopvac customer service today) is the recommended running time of any single stage shopvac motor is 45 minutes with an hour "cooling off" period. Running for longer periods at a time can result in the motor burning out or possibly fire. The larger industrial vac with a 2 stage motor can run continously.
I hope this helps

No, I don't think this is a problem here. The air in the box is floating undirected and there should be a absolute minimum of dust in the box's air.
It is a problem if one uses plastic pipes (drip molding ones) to exhaust the dust. NEVER DO THIS!
This needs metal pipes including grounding. Using plastic ones is dangerous!

This the set up I have shown before, all I have is a domestic vac that was given me that has a cloth dust bag that I clean every couple of days as the fine dust clogs it very quickly, the rest of my machinery I have a full size 2 horse power dust extractor and that is connected by a 4" hose to all my dust making machines, my planer and bench saw I use out side

Good work SawdustDave. Oh well when I posted it I thought it may have been a good Idea but now I stand corrected thanks for the heads up.
Good thing Steve posted this I was going to build one as soon as it was warm enough in my shop.
This is why this is one of the best forums out there (MOHO) Thank you again Steve and Sawdust Dave I agree with Steve don't worry about the floor till your done or take a break...

hmm... this gets me thinking too. I don't know. ???

I did ask the Vacume Cleaner guy ( not just a sales man but general all around about vacs) I explained what I wanted it for. He said the canister wouldn't overheat inside of the styrofoam box. I have checked after use and it doesn't seem to be any warmer than my upright household vac after doing the carpets. Is there a difference between shop vacs and household vacs?
-
A household vac runs alot cooler than a shopvac by design so it probably requires less air flow to keep it cool. But thats only an observation on my part.
