In my shed I have a basic, noisy 1500w Screwfix table saw. When I use
it I connect a 1000w wet and dry vacuum cleaner to the underneath
extractor outlet and an old 1000W henry type hoover to the overhead
guard. This takes care of the sawdust probably as well as can be
expected BUT THE NOISE IS DEAFENING, the lights flicker and it's
probably going to annoy my neighbours soon.

Is there some better way of extracting dust from power tools? Some
kind of cyclone thing? or a quieter single dust extractor. Trouble is
these days you just have to buy the stuff off of a catalogue.

Can you use an extension for the vacuum hoses to take the machines
some way away from the saw table? Maybe also use a bit of rockwool
insulation or expanded polystyrene around them to cut down the noise
(but not the air needed to cool their motors!)?


I am wondering if a muffler on the hoover exhaust would do any good.

I'd say the noise comes from the high revving motor and fan. To reduce
that, you'd need a slower running motor and larger fan.

+1, wet and dry vacs are pretty cheap and nasty. Henrys, on the other
hand, are normally remarkably quiet IMHO. Perhaps you need a new Henry.
You could connect this to a home-made cyclone collector, plenty of
examples on YouTube.
