I'm thinking of doing much the same thing for my little Sanford 4"x8"
Surface Grinder.

However, the device will NOT be used to do double-duty .. it will be a
dedicated device for Surface Grinder use only.

The plan is to build a little hood at the end of the table, with a hose
going
upwards to a typical blower/sucker.

(All the commercial units seem to try to catch the dust right at the wheel,
for
reasons that escape me; by catching it 6 inches away, much of the velocity
of
the particles has been lost, making them much more likely to be captured ..
or
so it seems to me)

Initial tests using a _small_ Shopvac showed this to be almost 100%
efficient in
capturing the dust, just darned noisy .. too noisy.

A portable dust collector setup should get it all, with much less noise.

What I'm not sure of is what to do with the exhaust. I could just dump it
outside,
but that seems like a waste of hot air in the winter; these things move a
lot of air.

So I'm left putting some sort of box and filter on the outlet. I'm thinking
about a
small version of the "swirl" type of units (using maybe a 5 gallon bucket
instead of a
garbage can, for all the dust that this little grinder will create) with the
outlet of the
swirl attached to the largest practical automotive air filter.

I'm also thinking about putting an inch of water in the bucket, to maybe
catch some
of the dust that way.

Any thoughts ?


Thanks in advance.

I just got a new G9975 Shop Fox 2 HP Dust Collector.
http://www.grizzly.com/products/item...emnumber=G9975

I am going to use it with my 2"x72" belt grinder and grind mostly
carbon and stainless steel but dust collector manual says "for WOOD
dust only!"

Is this "WOOD" dust collector going to have a problem with metal dust?


Thanks,
Alex
