Dyson cyclone based dust extractor - simple build

Recently I've found a need for a dust extractor to deal with woodworking dust. I didn't want to spend much, and I wanted one that didn't take up much space.

You can't use a vacuum cleaner alone for dust extraction, as the dust very rapidly clogs up the vacuum canister (followed shortly by clogging the vacuum filters). By using an additional cyclone system above a bucket, you can extract dust for ages as the bucket and secondary cyclone prevent anything getting through to the vacuum.

This is a very easy build. Just print out the pieces, cut a few holes in a bit of plywood and if you're feeling keen, route a groove in the plywood to match the bucket.

What you need:

A Dyson DC14 canister. I got mine for $30 from a parts sale.

A vacuum hose,

A vacuum cleaner,

Some adhesive backed foam,

Some screws,

Some 12mm plywood or other decent wood,

A reasonably robust bucket. Keep in mind it will be under vacuum pressure, and needs to have decent strength walls.

Diameters for these components are based on:

Vacuum cleaner hose - 41.7 mm external Ø.

Dust extractor hose at canister - 53.5 mm internal Ø

Dust extractor hose for tool - 34.75 mm external Ø

Tool dust extraction port - 37mm external Ø

If you have different diameters you'll need to modify or design a different adaptor.
