Dust extractor cyclone

Having watched a number of videos about home-made cyclones I decided it was time to invest in one now I have a table saw. The amount of sawdust it produces and the frequency with which my shop vacuum filter clogs meant I needed to do something.

So I ordered some parts from Amazon and waited for delivery. Disappointingly the cyclone part of the kit isn't coming for a couple of weeks, so I'm still emptying and unclogging the vacuum.

Eventually I was looking around the garage and noticed two old buckets. One had tile adhesive in it and one I think was paint. I use them for rubbish but it's time to repurpose them. I also had a bit of waste pipe.Now to get all Heath-Robinson and see if these two old buckets would do the job. Neither had a lid so I cut a ring from 9mm mdf and used a few dabs of CA glue to stick it to the smaller bucket and then some silicone sealant to make sure it was airtight.

I used the middle of the ring to make the top hose connection, primarily because the first hole I cut was too big! The side connection was another bit of pipe secured with a small bit of wood screwed through the pipe and the wall of the bucket. Again lots of silicone to seal.

Because I didn't have a lid for the bottom bucket I just used some broad black insulating tape to the strap the two together. The tape round the top was to hold the mdf in place. An old hose from another vacuum cleaner and the thing was built.

To test it I emptied the contents of the cleaner on the floor. The filter was already clogging up although I'd cleaned it a few hours previously.

Amazingly it worked! I didn't think the buckets were big enough to create a separator but they did. When I opened the vacuum cleaner there wasn't a hint of sawdust in it at all. Because of the tape I can't open the cyclone, or rather can't be bothered to open it, but all the use must be in there.

It's all very exciting and possibly the most exciting thing I've ever made.
