No WIPs I’m afraid
I was inspired to make this mini cyclone after reading tonytopman’s post which can be found here

Firstly all parts purchased off flea-bay: Dyson drum, acrylic pipe and sheet, waste bin.
I tackled the side inlet first as this would be the trickiest to get right. Measured the drum and pipe and then created templates here http://harderwoods.com/pipetemplate.php so that the inlet pipe would be 90 degrees to the drum.
Inlet at 90 degrees to drum
I cut the end of the pipe first using a Dremel and cleaned up the cut with a file. To angle the inlet I spray mounted some Aluminium Oxide paper on the side of the drum and then carefully sanded the end of the pipe to the required shape and angle, titling a few degrees at a time. The angle is completely arbitrary and just what looked about right.
Inlet angle
I then marked round the end of the pipe, cut inside the line (more like melted) using a Dremel to create the aperture and cleaned up with a file. Because of the large surface area created by the angled shape on the end of the pipe it could be glued straight on to the side of the drum.
Solvent Cement I used
After curing I used a long round file - poked down the inlet - to smooth the cut angle in the side of the drum to the same angle as the sides of the inlet pipe.
Next I created the bottom flange from an acrylic sheet. It has a rebate on the inside edge of the flange which the drum sits in to create a stronger joint. The acrylic sheet was cut using a standard 2 flute straight router bit. It would have been better to layout and drill the flange holes at this point but I didn’t and had a few nervous moments with a cordless, drilling the holes at the very end.
I then used the off cut to thicken the top of the drum; the glue up isn’t very pretty. Then double sided taped a template to the top of the drum and cut a hole and rebate for the outlet pipe. The top pipe was then glued in place.
Thickened top and outlet pipe
The bottom bin is a 25l brewing bucket reinforced with a couple of plywood rings which stop it completely collapsing when the inset becomes constricted.
Bucket with reinforcing rings
The inlet and outlet pipes are sized so a 32mm vacuum hose pushes very tight over the pipe so there is no need for tape or clips.
Performance on fine dust and small chips from circular saw, router table, and sanding is pretty amazing. I usually half fill the bucket. There is a teeny tiny amount of dust, if any, in the vacuum.
The build didn’t work out super cheap as I had to buy all the parts and solvent cement however, the main purpose of the build was to have ago at cutting and gluing acrylic for a big 125mm diameter cyclone build one day!
Completed Cyclone
