Made this a year or two ago, but just been browsing and noticed the photo's, so thought I'd post them.
Just a quick and simple take on the cyclonic setups. It's no work of art, but has worked well and survived well, considering it was just a quick knock together job to test whether it would work or not. Used a gas bottle as it saved farting about making a cone. Been in use for a good while now, and it functions all abouts as well as using a proper cone, with only a very small amount of fine dust ever making it through to the vacuum cleaner.
The gas bottle has a piece of 1-1/4" ally pipe going into the top which the vacuum connects to. That piece extends about a third of the way down the bottle internally. The other pipe, (again, 1-1/4" ally), is situated on the right of the bottle looking from the front, above the height of the internal end on the vacuum outlet, and is located so that it's outer edge is roughly inline with the wall of the cylinder internally. The bottom of the bottle has a 4" circular opening cut out with a plastic 4" adaptor flange screwed to it, (the type you use for connecting 4" ducting), sealed with a foam strip, with the same type of flange on the top of the collector, then obviously connected together with 4" ducting. The ally pipes are just epoxied in place, btw.
It's a handy bit of kit. Takes a damned sight more space than a vacuum cleaner alone,
but the suction is far better, (I also upgraded the bog standard vacuum hosing to 1-1/4" throughout), and suction doesn't deteriorate at a rate of knots as when using a cylinder vacuum as is, and it's a doddle to just flip the lid off the collector bin and empty that instead of phaffing with the cylinder vacuum itself. That collector bin has needed wedging in place with a length of wood to stop it prancing around like a harlot once switched on though.
