Thread: dust extraction for foam
The cyclone has no noticeable difference on the power of the vacuum. I've got one of the newer Henry's with the Hi-Low setting switch and rarely switch it to full power. I imagine on your machine you're going to have quite a distance of plumbing between the inlet/dustshoe and the cyclone. I'm not sure if this distance has an effect on the suction. I do know that smooth walled pipe will give you better flow than ribbed hoses.
You may want to consider earthing the plumbing too. Mine creates quite a bit of static and makes my hair stand on end if I lean over the bed on my machine lol.
Dean, I wasn't sure whether Clive was setting me or you up, or whether he was having a 'senior moment' :p It's probably just payback as you were a day late getting to his place cos of me lol.
I cant have the vacuum to close as the bits are quite long and they have to cut quite deep. I'm wondering if I can make something that makes a bit of a cyclone erect comeing out of the dust shoe to help get the foam up from further away perhaps.

There is an 'improved' version of the ebay cyclone (a bit more expensive) at
Looks pretty good.
Looking forward to seeing the first boards coming off your machine.
Cheers yea that what I had my eye on
After a bit of experimenting I have ended up going with a high velocity low pressure bag style vacuum unit I got used of eBay nice and cheap and local. I thought this was the best solution because the foam dust is so light and the hvlp units are nice and quiet. The only thing now is trying to decide how to run the vacuum hose and in what size. The unit will be at one end of the 6meter table so can't decide if to run a solid pipe to the centre and then come down some how with something flexible or to have flexible the hole way on some sort of curtain rail type thing
You want 4" pipe minimum I would think, 6" even. I would use solid pipe as much as possible, people use the 4" soil pipes. Flexible pipe has ridges where the metal spiral is and this restricts flow.
If you use plastic pipes you need to wrap some earth wire around them to drain static away, some people have experienced explosions.
