Re: Building a closet for dust collector
So Glen, you never tried one piece at a time?
Bill Belanger?
Joe, This is how I did it. I spent a lot of time laying it out on paper, pin pointing my exact location drops. After many layouts when I found the best one I ordered the parts. While waiting for delivery I layed out my plan on the shop floor with a marker. Then using my laser I shot up all the lines and hung the threaded rod. When it all arrived I pre assembled everything on the floor and cut all the pieces. I hung pulleys above each section and my friend came over and we hoisted up 20n to thirty foot sections. I went very well limited ladder work and all done in a day. However 30 ft of NordFab at a time was way heavier than I thought. It all worked out great. Last thing i wanted to do is to try to take measurements, cut pieces, and try and clamp all those connectors 16 feet off the ground. If I ever had to do it again and I will for the addition, I will do it the same way. Glen

Re: Building a closet for dust collector
Of course you don¡¯t want to pay a lot of money to condition air and then blow it all outside.? But it depends on climate and how much you use it.? Obviously in a professional?shop running 8 hours a day in snow country,? blowing outside seems impractical.? ?But a hobbyist running a cyclone intermittently in a moderate climate is not going to see a significant impact on air conditioning bill.
Once upon a time, I had an Oneida inside my shop.? Several years ago, I built a "lean-to" shed behind the shop, I removed a window in the back to allow the room for the duct work to get to the dust collector and air can return.? I looked up the pros and cons of exhausting to the outside with a seal.? I keep my shop climate controlled and it was my understanding that when you suck air out that is not good for air conditioning.? By having an opening, that allows the well insulated shed to be climate controlled.? Sure, there would be less noise if totally isolated, and I very much like quiet when it comes to noice from things like air compressors and dust collectors, but for me, noise is not a problem.? If I had a very noisy dust collector, that would be different. Fortunately, my dust collector is extremely quiet. ?
I have been very happy with my shed.? I "bought" space inside the shop.? I do think it is a bit quieter being back there even though there is a connection, and it is setup where there are larger "French" doors in the back so when it is time to empty the dust bins, I wheel the green waste cans to the door, and empty them where if any dust gets on the concrete outside, no problem.? Dust in the air blows away.
Anyhow, just some feedback. ?

Re: Building a closet for dust collector
My closet cut about 10dB.? ?There is huge difference between 76 and 86 dB of course, and if you want to work without ear protection, a closet will will?get?you there.? Not silent by any stretch, but comfortable.
Yes on the STC specs.? I¡¯m not worried about the frequencies below 125hz, at least to my ears they are 1Khz and higher.? The collector is supposed to
be only 86db but I find it annoying.?
?
Maybe I¡¯ll hold off for a while, still need to install the duct work.

Anyone have advice on holding two pieces of Nordfab and snapping the clamp on? Seems like a two person job?

Re: Building a closet for dust collector
If you're lucky enough to live where you can exhaust outdoors, that's the ultimate "silencer".? It's also improves flow and eliminates filters.? ?
Mine exhausts thru?roof, pointed about 30¡ã from horizontal away from my close neighbor.? You might be surprised at how tolerable the noise is.? None of my neighbors have ever even commented on it.? It's a very low-pitched sound and when blowing into open air dissipates very fast, unlike when blowing into a shop where it reverberates around.??

Re: Building a closet for dust collector
Line the exhaust baffles with sound deadening foam and it will really cut down the noise transmission. Did that on a air handler that was in a closet close to a living room and the difference was amazing.

Brett,
I was just kidding, not really putting the product down. My shop door have MDO for exterior cladding and are doing just fine after 18 yrs. Although, that is an ancient product.
I watch this old house and read JLC online letters - recently started getting their print magazine - but had not heard of exterior MDF. Fact that you prefer or PVC for trim is worth knowing.
Last time I looked for siding options I discovered a product made out of ash, cannot remember the name but it was rated for ground contact. IIRC, my exploration stopped when I learned each board was $60. This however is something to consider for trim. Not sure how it compared to marine grade MDF.

SL (Stephen) - aha! yet ANOTHER "Medite" variant, but that is structural? Another product to investigate for applications I didn't even know I needed.

? Shellac?that won't cure up:
1. Get it above dewpoint?- hot air, in the sunshine, infrared, etc. It can fool you since it also softens with heat, but if you don't push out the alcohol and water, it'll sit there indefinitely. I once had a trunk finish in shellac on a February wet day, and it didn't cure for a month until it got in the sunlight. Also remember the moisture gets pulled into the alcohol when it evaporates and cools below dewpoint.
2. Spray naptha or better yet lacquer thinner over it. Sometimes it can "pull" enough of the solvents out of the coating to dry out faster overall. DONT use acetone - it will blush unless it's hot enough, and if it was already hot enough, it wouldn't have a curing problem.
3. Wait a couple more days and don't touch it and see if vapor pressures end up taking care of themselves.
4.? Sometimes the tackiness in the shellac isn't lack of cure - it's waxes and soft resins.
5. If the topcoats are compatible solvent, who cares, just spray over and it will settle on it's own. I suspect you are pouring some kind of epoxy, then that's probably an expensive risk. I am making a bar for my son. The top is walnut burl veneer over which I will be pouring a clear resin. I used shellac to seal the veneer before pouring the resin. Usually I mix my own shellac from flakes but I got lazy this time and used Zinsser Bulls Eye from a can. I thinned it with denatured alcohol to about a 1.5 pound cut. The shellac will not completely cure. I tried sanding but it just immediately gums up the paper. I was going to try wiping next with a rag soaked in denatured alcohol but before I did I thought I would reach out to the community for suggestions. Thanks in advance for any help.

Re: Building a closet for dust collector
This is a modern and probably easier to install version of something that used to be called ¡°resilient channel¡±. If it is installed properly it is pretty effective; if you use screws that are too long and go through the channel into the
stud you will short circuit the isolation and lose almost all of the benefit.

I will install 5/8" drywall inside, a layer of green glue, and a second layer of 5/8" drywall over that and then 5/8" drywall outside. If not quiet enough I will install green glue
and a second layer of 5/8" drywall outside.
I need a door to access the drum and a door to access the filters.? I am fairly certain I will do some sort of stress skin construction for the doors.
Any suggestions on how to get the dust inlet sealed to the sound proof wall?? I am doing a folded duct with 5X the cross sectional area of the exhaust port for flow the air conditioned air back into the room.

Re: Removing Uncured Shellac
Shellac?that won't cure up:
1. Get it above dewpoint?- hot air, in the sunshine, infrared, etc. It can fool you since it also softens with heat, but if you don't push out the alcohol and water, it'll sit there indefinitely. I once had a trunk finish in shellac on a February wet day, and it didn't cure for a month until it got in the sunlight. Also remember the moisture gets pulled into the alcohol when it evaporates and cools below dewpoint.
2. Spray naptha or better yet lacquer thinner over it. Sometimes it can "pull" enough of the solvents out of the coating to dry out faster overall. DONT use acetone - it will blush unless it's hot enough, and if it was already hot enough, it wouldn't have a curing problem.
3. Wait a couple more days and don't touch it and see if vapor pressures end up taking care of themselves.
4.? Sometimes the tackiness in the shellac isn't lack of cure - it's waxes and soft resins.
5. If the topcoats are compatible solvent, who cares, just spray over and it will settle on it's own. I suspect you are pouring some kind of epoxy, then that's probably an expensive risk.
I am making a bar for my son. The top is walnut burl veneer over which I will be pouring a clear resin. I used shellac to seal the veneer before pouring the resin. Usually I mix my own shellac from flakes but I got lazy this time and used Zinsser Bulls Eye from a can. I thinned it with denatured alcohol to about a 1.5 pound cut. The shellac will not completely cure. I tried sanding but it just immediately gums up the paper. I was going to try wiping next with a rag soaked in denatured alcohol but before I did I thought I would reach out to the community for suggestions. Thanks in advance for any help.
