looks good, can we have some more information on the extractor you are using?
I've seen the bouncy castle blowers on ebay but no information on volumes of air moved, audible volume etc.
Here's my recent post about the DIY Extractor as far as technical info on air volumes etc I haven't a clue and regarding the noise......my set up is quieter than my old "Proper" dust extractor that sounded like a VERY LOUD vacuum cleaner.bouncy-castle-blower-dust-extraction-cyclone-t109696.html
I tend to make things that i need and if they work its a bonus, its better than wasting money on something that the manufacturer claims to do the job when in reality very few do unless you spend ££££££££££££££££££££££££££.
My extractor is linked to a drill press/drum sander fitted, my scrollsaw, my bandsaw (the suction is there on the bandsaw but the dust collection ports need redesigning as they bandsaws case leaks air/dust all over) my bench belt sander and two bench mounted dust ports (as above) I can isolate any of the machines using my blast gates (if you close all the blast gates apart from the one you are using you get the full power of the blower which is like a jet engine so very powerful)
The blower doesn't get hot in use and I checked the two Hepa filters last night and no dust in them but around 1" of fine dust has collected in the metal cyclone/bin so its doing its job.
Sorry can't be more technical about airflow but its beyond my grey matter
