Hi, ALl, I was wondering whether anyone is familiar with air-
filtration/fume hood type systems suitble for a very small in-home
glassworking bench. 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!

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 ))

In calculating fan capacity for fume exhaust there are type A and type
B exhaust requirements. Flux fumes are noxious and rated as type A.
That means your fan capacity should be 125 times the face surface area
of your hood. If you have a 24" x 30" hood, you need a fan that draws
625 cubic feet per minute.

Many glass artisans (for stained glass and torchworking) have rigged
an overhead hood with an inline duct fan like these:
