Durning my working life I was exposed to some very hazzardous chemical vapors during the early days of my work life. Later as the safety laws came in I had much better protection. Now as I look back and think about the guys that have died in their old age, most had been exposed to these bad things. Their deaths were all in some way connected to their exposure. Most had COPD related issues.

 

Having said all that...........I can see NO circumstance where you should even think about taking any chances breathing anything you shouldn't. Get proper protection, a little research will go a long way.

Dragon................It is only zero and colder up here this time of year..........and venting to the outside is not an option. Only during our 2 months of summer. :-)

The reason I want to try charcoal filters is to try and clean the smell out of the air. It can hang in the shop for 2 or 3 days or longer.

You could test it by just spraying lacquer thinner and have somebody else smell for it outside. but if no neighbors to offend, are you looking to just filter the inside air in the shop?

 

Maybe you could just vent to the outside with a squirrel cage and a peice of 4 inch pvc with a cap on top?

Wayne............I really think what I have is a variation of what you are trying to locate on the net. I have a sanding down draft table that has 2 stacks of 3 furnace filters. I put an inexpensive..........I think 8 merv on the top and middle with a 12 or 13 merv on the bottom. After I used it for a while, I found that is a very good air cleaner also. It circulates my shop air and within 15 minutes my air is probably clean as hospital air...............no kidding. And that's checking air quality with one of those dilos air quality moniters.

Anyway...........this is what I want to mount charcoal filter in.

Searched hi and lo. Can't find aything but the fans and furnace filters gig. Figures, about the time I forget about it I will stumble across what I was looking for. Just like in my shop. All I can say at this point is with age comes wisdom, and a certain amount of senility.  I just hope I remember to retire when the time comes.

Never tried it Gary.  Would it dry?

Gary Heltemes said:

Oh, ya, Your right. I have started using a little shellac..........as in padding. I got a lot to learn. I'm going to mix up a fresh batch of flakes and try brushing and see how that works. In my case............I have nothing but time now that I'm retarded, I mean retired. But I still go lacquer. Go figure???

Question for ya ron...........If you mixed 1/3 each

BLO

-MS and poly, wouldn't that be that rub in varnish..........or whatever like formby's???

Mike. I'll have to look for the General Finishes around her and give em a fair shake.

Oops sorry the fingers aren't working so good today "...rid of the perfume

Gary.....

Water-based wasn't to bad. What I do, spray coats 1 and 2  kinda of light. My 3rd  I will spray pretty full and wet (3 to 4 mils) and the finish will start to take a  bluish hue and orange peel. Basically, full and wet and looks terrible. But....it just flows out really nice.

I have sprayed only a couple of the other water-based brands on the Market, but none can compare to General Finishes, in my opinion.

Ron.....

General Finishes has a nice outdoor water-based which is formulated to be more flexible and not crack and flake off when wood expands and contracts from moisture conditions being outside.

 

 

 

If I tried the mix, it's was a long long time ago.

But, why wouldn't it dry???? The BLO is a product a lot of us use to pop the grain............so it dries. Mineral spirits is a product I use for cleaning a brush, or whiping the sanding dust before spraying lacquer.........so it dries. Then there's the poly.........and that dries. All we've done is thinned the poly to a whipping consistancy.  I don't know the  purpose of the  BLO.........but it's in the home brew formula. If you have these on hand, mix up a 1/4 cup of each...........and give it a try. Nothing ventured..........nothing gained......right??? Put a coat on..........let it dry overnite and put on as many coats as you like, till you get the look you want, because each coat will build the finish.

I don't know where guys get the Idea that BLO and other things will not dry, I think its a silly notion Sure it may take longer to dry than other finishes.

If you look at mineral spirits, since its thin and drys (evaporates) slower than denatured alcohol, lacquer thinner even naphtha. Since its so thin and depending on the wood type (more porous) say a poplar, the mineral spirits gets pulled way down into the wood (absorbed) therefore taking longer to gas off or dry. Now to dry, the mineral spirits has to  expel Itself back up/out through the finish, thus slowing the cure or dry of the finish.

 

There is no right or wrong...its just a path you take.

 

In conclusion, I guess if your in the professional world of furniture finishing and need to bang out furniture, slower curing finishes aren't best suited for you?

I probably sounded pretty naive' Mike.  It will definately dry but I wasn't sure how long it would take it.  When I mix finish it is usually tung oil and minieral spirits or BLo and mineral spirits.  I've never mixed multiple ingredients and didn't know what the dry time would be.  Besides, I don't have a white lab coat to play mad scientist.

Hold on hold on Ron...my comment wasn't directed at anyone, sorry if it came across that way. No! No! Noooo!...

 

As fars as the white lab coat I don't have one either. Merely an effort to help those understand the thought process of how oil finishes dry. Finishing is a personal thing. We Guys and Gals just use different approaches. And that's ok

 

Its ok to mix your own finishes. And its ok to buy finish manufactures pre-formulated products. Finishing can be tough. Sometimes guys will blame a finish, but we really have no one to blame but ourselves.

 

 

No blood.....no foul!

Here's the link foe typing in "Charcoal air filters"

You should be able to recycle the air pretty quick with these.

 

You could also build one of these:

 

Look under "canister charcoal air filters"

Hey dragon........I bookmarked that link so I can call them tomorrow. They say they have paint booth filters and this may just be what I am after.

I'm also thinking a barrel or rectangular box with intake pipe on lid being fed from ceiling of shop and a vacuum hookup at bottom of box would work too.  Just fill and run.

You also could build a smokeeater and fill it with those charcoal filters.  Would only require 2 box fans and the filters.  I've built them before.  Let me know and I'll help.

I've already got a down draft table with furnace filters. I just want to pull those filters and use charcoal for the short term to clean the stench out of the air. It circulates my shop air fantasticly.............so I don't need another contraption in my shop taking up valuable space. :-)

Gary

I did find that article. It was in Woodcraft Magazine sept 2010 Issue. Both instances were vented to the outside though.

The article was about portable paint booths.

I have read the other posts and see that you may have gotten the answer. Just wnted to let you know that I din't give up on it.

Also this article may be of help to someone else.

Best of luck

My material supplier, upon request adds a product that imparts a vanilla odor to the lac. I use hvlp so I'm putting most of the stink on the product without putting 40% in the air,so neighbors think I'm baking cookies.
