Best would be somehting that coudl be lifted onto the working surface during soldering/grinding (tho' I intend to do most of my grinding outside, as I have a covered porch), then lifted off and moved when I'm either scoring glass, or using the table for some other purpose. TIA! - Kris Hakko makes a good fume trap and if you have a way to vent the air outside you could juririg a stove top exhaust. It's the fumes from the flux that you need to vent away not from grinding unless you are grinding dry. Thanks, I'm looking up their info ((I'm trying to decide whether I should go for a fume hood or fume collector, or whether I could get away with turning my Miele on and wiring the nozzle to the desk (it has a HEPA filter and I can get either super- filter bags, or HEPA bags for "double filtering"), or whether I should get a window fan (pointed outdoors) and rig up a duct. Or maybe just get a small folding table and chair and do it outside before the day heats up too much )) - Kris One thing to consider is that HEPA stands for (more or less) "High Efficiency Particulate Air" filter. The key word here is "particulate". Although they are very good at trapping very tiny particles, there is a lot of non-particulate stuff (fumes) that are released during soldering. HEPA won't do squat about those. Like Chemo noted, you need a fume trap (does Hakko make one big enough for sg work? I only know of their electronics stations). A homemade fume hood using a stove hood and venting *outside* would be much better than any filtration system. Just extend the sides of the hood down further towards your bench. Of course, there are advantages for good air filtering as well, but ridding a shop of fumes ain't one of them. Joe HEPA filters are great for filtering out dust and such but are pretty much useless for removing aerosolled flux fumes. This can be easily demonstrated by placing a piece of cloth or paper towel over the exhaust - which will expediently dampen from the condensed flux. Use filters to remove dust. Exhaust to outside to remove noxious fumes. Below is a link to the Hakko fume extractor. It explains the filters used. These are the same type of filters that are used in the Honeywell 17250 HEPA air cleaner that I liked to in my earlier post. http://72.14.205.104/search?q=cache:...ient=firefox-a |
