I know my 1700 CFM 2 stage dust collector is way quieter than a 6.5hp shop vac
Wow Tom that is a great post on dust collection with a lot of information. Can you post a picture of your miter saw dust collection? I would be interested in seeing what you did. Here is what I did but I am always looking for better. I use both a shop vac and a big dust collector.Hi Herb,
As you know I've spent a lot of effort on DC stuff. My small shop has really altered for the better after installing a Wynn 1 micron drum filter on the HF 2hp unit. This thing really pulls a lot of air and almost nothing in the way of particles gets away. The other thing that has helped is the installation of a WEN filter, the cleans out the fine, airborne particles that never make it to the DC. It is pretty cheap on Amazon.
The rest of the stray sawdust is from the top of machines, And that takes hoods and individual DC solutions. I recently bought an over arm DC for the table saw, but haven't had time or energy to put it in place. I have a good 10 inch saw with excellent below table dust collection. DC already exists on most of my other tools. Some are better than others.
I contained the messiest tool, the sliding miter, by hanging a clear shower curtain around the back side of it. By pulling the blade through the piece toward me, a chute is created that when I push back to complete the cut, throws nearly all the sawdust back into the curtain. The curtain is gathered at the bottom into a box with a DC fixture on the bottom. But it's that pull-push move that really does the job, not so much the suction.
Add a chip collector to your DC unit. Lots of good designs out there. Pick one.
One thing I think you'll have to address is carrying the sawdust up on your clothes and shoes. If momma don't like it, it's time to make some changes. Here's what I'd do:
Get a dust collection fixture that makes it easy to vaccum up the floor every time you do some work down there. My DC has a 4 inch tube (rockler with a wide spout) to pick dust up off the floor. Don't let it sit there, it will find its way up
Install the WEN (now $118) https://www.amazon.com/WEN-3410-3-S...TF8&qid=1492735301&sr=8-2&keywords=WEN+filter
Find a way to brush off your shoes. Try this, but mount it on a box into which you can plug your DC hose. https://www.amazon.com/Boot-Cleaner...1492735463&sr=8-4&keywords=shoe+cleaner+brush
Along with brushing off your shoes, find a vacuum attachment that will let you vacuum off your shirt and trousers. Do this very thoroughly or momma won't like it. If you have sawdust in your hair, you can vacuum that off too, but don't go after your ears. Sawdust in your hair gets on momma's pillows.
Consider getting a full coverage apron to catch as much sawdust as possible. Close up the pockets. Vacuum it after use. Denim Woodturner's Apron | Rockler Woodworking and Hardware
If you can manage it, find a way to lay down some linoleum or paint the floor to make cleanup easier.
Clear away everything from the floor, up the wall 16 inches to make cleanup easier to do.
I'm sure you could do a lot more, but these fixes really worked well for me, and didn't cost that much. The Wynn canister filter was the big item, the WEN unit wasn't bad, the shower curtain and hanging hardware was maybe $25. I already had the long 4 inch hose and fixtures. A small price to pay for peace at home.
I coincidentally built a Shop-Vac cabinet back in the pre-youtube days that looked just like the one in that video, only it hinged open from the top and was 3/4" particleboard. Same result as yours. I was pulling dust off a guitar body while a friend was routing it and he was shocked. He said he thought it was off, then the dust just started flying into the hose. Sadly, when I upgraded to one of the newer yellow and black ones, the stock unit was nowhere near as irritating and wasn't worth the hassle and space of another box.I run mine in a similar cabinet to this and the noise has dropped from an ear piercing scream to a low whine that can not be heard when any other machine is running.
Running a ground wire solves that, but I wasn't suggesting wrapping the whole system, just key points, such as the impeller housing and the ports in and out of that. A chip collector also seems to help reduce noise as well. I was hoping someone could give a name to that gooey stuff used in cars for noise suppression, about half an inch thick, it would be easy to cut to shape to fit the impeller housing, which is where most of the noise originates in my system. I also keep several pair of "ear muffs" around since my hearing is already pretty iffy. Too many rock concerts in my past.Dan, sorry, that remark was not aimed at you as such, just a response to the thread.
Tom, there is a small risk completely wrapping the system in foam. Yes it cancels the noise, but you would need to earth the pipework in several places to stop a spark igniting the dust. This is a risk anyway, but with the piping all wrapped up, a fire could start in there anmd you would not be aware of it untill it melted its way out and burnt the place down.
@kklowell I think I found the original product. Adhesive, thick, Dynamat 11103 Dynaliner 32" x 54" x 1/2" Thick Self-Adhesive Sound DeadenerI remember that product well, but unless it was called "sound deadening mat" I can't remember its name.
