Where abouts can you buy cheap thin aluminium sheet?

S. Heslop:
I need about 1000x1000mm of aluminium sheet, about 0.5mm thick-ish. Something I can roll into a cone to make one of those famous cyclone dust collectors with.

Went to Wickes today and didn't have any luck. The usual metal merchants I go to sell it for ~£40 for that amount, which seems like alot of money. In videos people seem to be using a sort with paint on one side, and one guy called it 'flashing'. The only aluminum flashing i've found is narrow stuff.

I could just go with plastic though, but i'd rather get something that holds its shape easier.

If you look on youtube there's a bloke who's made a cyclone dust separator using a large traffic cone.

May involve a bit of nefarious night time activity but there's the cone already made for you  :ddb:

Funnily enough, i'm copying that guy's second cyclone, since he lists the dimensions. http://woodgears.ca/reader/marius/dust_collector.html Although I'm using a bouncy castle blower I got at a boot sale.

I really want to build a gigantic dust collector and put a pipe in along the wall of the garage. I was using a small numatic vacuum cleaner for a while, but it's been overheating lately. It's also inadequate for drawing chips out of a planer/thicknesser I bought a while back (that's terrible! I'll probably have to fiddle with it a bit to get it working well). But most of all I just hated moving it about since it usually involved balancing it on top of the assorted rubble that accumulates on my bench tops.


Edit: Actually, looking at it. I guess that guy's traffic cone cyclone isn't THE traffic cone cyclone. What I find odd is all the videos on people making cyclones to hoop up in line with their big expensive industrial dust collectors. It seems kind of pointless if you've already got a working dust collector to add a second stage to it.

Simon I also aspire to a central duct in my wood work shop and some time ago bought various shut off gates, and one of those superb floor openings that you sweep your shavings into.

I have three (!!!!!) suitable large bore extractors, one came with my woodturning lathe, one I bought for my rip saw / planer combination woodworker, and the third I got as it is wall mounting and I intended it as a central system to save floor space. However as usual other tasks took over, and I've plumbed the floor standing one directly to the Dominion Woodworker as I found I was using it 'just for little jobs' with no extraction and it was getting packed tight with dust.

The advantage of the cyclone it that most of the collected debris (some claim 98%) is dropped into the collector without clogging up a filter, hence the air flow remains high for much longer

I was planning to use 110 mm soil pipe as the spine with drops to each machine isolated by a shut off valve

Really I need to decide which extractor I'm going to use permanently and shove the other two on ebay to free up space in my storage container
