turns are bad for airflow, but it's what I'm forced to do in the current location (garage wall). |
Can you install a louvered outlet in the peak of your attic? If so, mount the blower just inside that peak. A squirrel cage blower will make the
90° turn for you.

Magpie: Do you mean an outlet in the side of the house (facing the street), instead of putting one in the roof? Like this:
That's an excellent idea. That way I don't have to punch a hole in the roof using my godawful carpentry skills, nor would I have to have an unsightly
pipe sticking out above my garage. This would also give me more room to gently bend the pipe and not have to maneuver around sharp turns.
The problem then becomes that I would probably need to keep the garage door closed when working, so fumes don't drift down and back into the work
area. It'll get hot out there in the summer!

Yes, that looks like a bisected grate in that peak. It would be better if the grate were located a foot or two lower so that it would mate up better
with the blower outlet.
Yes, you can't leave your garage door open when using the blower, other wise you would be "eating your own dirt," so to speak. I leave the garage
door open to my living quarters then go to the other end of the house and open a bedroom window. This draws fresh air into the garage that passes
through the whole house. And yes you pay a heating or cooling price for using that conditioned air. Nobody said safety was cheap.

if it goes up through your attic, make sure you consider safety first. perhaps a good air duct (rolled sheet metal kind) if there is a chance of
sucking up flames from a broken piece of glassware. you really don't wanna have a problem with flame, some of the cheap dryer vent flex tube and
forced air. especially in an open beam part of the structure you live in. you should really check with local standards first and foremost.
I installed 2 vent fans for a glass blowers studio, both 12" inline exhaust fans. One under the eve near the peak, the other was through a window I
pulled out. we kept the eave vent intake well away from all heat sources. the window one behind the torch was set in concrete board and had no
ducting behind it to burn out. we observed all safety requirements and it got plenty of use safely.

Thanks, Magpie. This option is definitely something to think about.
violet sin, I don''t think flexible dryer tubing is suitable for a fume hood line. They are made from thin aluminum, which would
quickly corrode if any acid fumes are passed through them. My thought was to use PVC piping. This probably isn't great for solvent vapors, but
hopefully stands up well enough to last (plus I don't generally use organic solvents). If it does get eaten up I can easily pop in a new segment.

I was just pointing that out. the flex tube is not a good idea, though its commonly used for bathroom vent/light combo fans. and it would surely be
recommended by a home improvement store employee if you gave him scant details on what exactly you were doing. so thought I would bring it up.

Apologies, I must have misread your post. I get a lot of weird looks when I try to describe my construction projects to hardware store employees, for
sure.

Hi we just recently finished our fume hood and so we are posting pictures.

That is a gorgeous workspace! I am also jealous of that vacuum pump. I have the single stage version that pulls 30torr and would love the versatility
of the two-stage.

Mine is to have a little OCD. Stealing cabinets is very relaxing, like meditation and it allows you to put stuff under lock and key.
SH, can you give us a tour of your lab please?

Sure, Pyro. I will one day. It is rather impressive. I would just like to get it looking presentable first. I know that no one will judge me on how
neat it is, but I need to clean it anyways, so this is a good excuse

well then, PICS! I am always curious to see other peoples labs to be able to
look at alongside of mine so I can see what I forgot.
I would post yet another lab tour since yet more things have been changed, but I think people here are sick of me posting a tour every time I make a
change

Here is my lab;
Some glassware;
And my element collection (I have many gases including Br, Cl, He, but the ampoules don't fit in my home made case).

nice one pinkhippo.i have been thinking for a long time that the key to a clean lab is to have white walls and if possible floors.if i ever get a
chance to build a lab i will first paint everything white acrylic latex or shiny oil base white.it is easier to find spots and splatters and small
items in a clean white room.

Thank you and yes, it does make it easy to clean, although the floor and lower portions of my walls are cement. The downside of white walls is that
once you get a little bit of a dye, like Fluorescein on them, it gets every where and when you try to wipe it up, it just spreads further.

Wow the labs posted in the 2 last pages are awesome, I look forward to making money after my studies and not have anymore to plug my distillation
apparatus in a 2m² bathroom on a chair and experiment outside at -20°C when bad gas are released :p

Here is my lab
I promised Pyro a tour, but I kept forgetting... but... I don't break promises, so here it goes!
<img src="http://i1373.photobucket.com/albums/ag387/sciencedean/20140104_200259_zps0cae1c50.jpg" width="800" />
That is the main part of my lab that you see when you walk in.
<img src="http://i1373.photobucket.com/albums/ag387/sciencedean/20140104_200358_zpsf375c1fd.jpg" width="800" />
Here is my microscope, it hooks up to the computer. It is one of the Chinese ones, but it works awesome and is of nice quality.
This rolly-cabinet with the rolling door is where I keep my organics. It actually is almost air-tight.
<img src="http://i1373.photobucket.com/albums/ag387/sciencedean/20140104_200556_zps093bdf37.jpg" width="800" />
Just a bunch of stuff; including my HUMUNGOUS fire extinguisher.
Above is a counter with a cabinet where I keep my poisons (And burnt out light bulbs).
<img src="http://i1373.photobucket.com/albums/ag387/sciencedean/20140104_200702_zpsccb16e9f.jpg" width="800" />
Fume hood.
<img src="http://i1373.photobucket.com/albums/ag387/sciencedean/20140104_200720_zpsfde1c7c1.jpg" width="800" />
Right of the fume hood. Part II on its way.

My milligram balance. Ohauses are great, renowned, and reasonably priced.

No... I have never made potassium, and I probably never will.<img src="http://i1373.photobucket.com/albums/ag387/sciencedean/20140104_200808_zpsd352e193.jpg" width="800" />
Random stuff under my balance table.
I keep a lot of stuff in here including my rock collection and jointware.
<img src="http://i1373.photobucket.com/albums/ag387/sciencedean/20140104_200906_zpsa7065d62.jpg" width="800" />
Example of one of the drawers.

Glassware cabinet. Notice Albert Einstein bobblehead. This is not all of my glass. Some of it is dirty and sitting in the sink.
Part III to come

That is my lab. Hope you enjoyed (That means you, Pyro)

I am jealous of the fume-hood and the storage available! I notice a trend that most of us find that our best chem supplier is elemental scientific. I
hope they stay in business for a long time. Based on their backlog, that is hopefully a long way off...
