Shop Vac Dust Extractor Dyson DC22

thingiverse

Human: Hose intake nozzle to convert a Dyson DC22 into a high-capacity shop vac for CNC router use. I acquired a Dyson DC22 motorhead, which I purchased for $5 from a Dyson used parts seller on a classifieds site. I chose the DC22 Motorhead because it features cyclonic stages - the first is the intake canister for large shavings and so forth, the second is a larger inner cone, and the third are 14 small cyclonic separators for fine dust particulate. Had it not been for price and availability, my first choice would have been the Dyson Ball with oscillating ends on the cyclonic separators, claiming you don't need a final filter. However, the DC22 is not passing any noticeable fine dust particles. I needed an intake hose adapter, so I created one to accept a 40mm diameter hose; you can make an adapter to reduce it to your hose size. I have also included a PDF file in 300dpi to CNC cut a mounting flange for the canister and a bottom internal cyclonic end cap. I used a 6mm thick clear perspex, pocketing the sealing grooves and flange canister locator with 4mm pockets. I routed the top of the canister flat so that I could glue a 135mm perspex disc that will accept a vacuum motor; you can design this yourself to suit your motor type. I used a small low-noise 600w motor from a $10 second-hand handheld vac, which I will replace with a brushless motor when I find one. I removed the trapdoor lid from the bottom of the collection canister and used a small grinder to remove the hinges and latches from the bottom to mount the flange. For the dust collector, I used a home-brew fermenting drum with a screw-cap lid. You will need to adjust the outer flange diameter to suit your drum size. The plastic used did not bond with Araldite 2-part epoxy. Instead, I used silicon and superglue with baking soda for bonding.
