I know you have space limitations, but you could get one of those ash filter metal canisters with a clip on lid. I bought one for around a tenner from CPC. ALDI do them every so often. There was a thread about it a couple of years ago - search the forum for 'Ash can filter'. The cyclone I made was not very good and the one on Amazon you point to may be what I should be using.

I am wary of using vacuum cleaners as dust extractors as the motors are not designed for long periods of continuous operation, besides the buggers are noisy.

I am unfortunate in that I am allergic to domestic vacuum cleaners and cannot use them. I also have to keep out of the way when my wife is vacuuming. The condition is getting worse and is extending to most forms of household cleaning tasks.

Cheers,

Rob
