Dust & chip extraction for shop
SwarfnStuff:
Hi Loply, I have a small vac under one of my shelf units and made my own cyclonic separator (also small), but I get very little stuff through to the actual vac bag - only the lightest fluff as a rule. They are not difficult to knock up really. And, yes, the long spiral stuff does get stuck in the hose at times.
kwackers:
If you're picking up mainly metal then you don't need to bother with a real cyclone.
Find yourself a metal bin/bucket or whatever and fit two connections to the lid, inside you place two deflectors (or elbows) to angle the flow in some arbitrary direction (e.g. clockwise).
You'll find this will be effective at removing 99% of everything that comes in (even works fairly well with wood / chippings etc) leaving a small amount of dust to get through to the vacuum bag.
You can then use whatever vacuum you fancy, I just use an 'Henry' since they're very 'sucky'...
(You could use plastic for the container, but bear in mind a vacuum pressure of 3 or 4 lbs/sq in mounts up over the surface area, so make sure it can handle it without collapsing).

Aldi have such a beast coming up this Sunday: http://www.aldi.co.uk/uk/html/offers/special_buys3_26897.htm
Not worth making your own at £15.99
Not sure if it's at all cyclonic but as kwackers says that doesn't really matter for swarf.

Hi Phil,
A pal of mine bought a cheap one of those to clean out his woodburner. It collapsed inwards under the vacuum the first time he used it. It wasn't from Aldi; theirs may be stronger. If it isn't, they are very good on refunds.

Perhaps he forgot to let things cool down :hammer:
I bought a quite efficient vacuum cleaner( not a bit o'spare piping) from either Lidl or Aldi last year. It was designed for 'barbees'- whatever they are.
Not a bit of bother, it not only cleans up turnings but grinding dust, odd pebbles from cars which my wife insists on carrying into my cars and grass and so on.
For those who want a pretty decent tool, a second hand wet and dry 'Vax' from a second hand market works remarkably well - for a £10 or less outlay.
