I have built a unit using the pentz spreadsheet. It's very easy to use and give good results. Mine uses a bucket with the bottom cut out, the cone is aluminum sheet used in house sidings. Some wood parts and 2" PVC inlet. I used pop rivets and a squierel cage blower but also did some tests with the shopvac. The inlet is too small but still, it works...

It is quite impressive to say the least but the blower lack power tremendously. It is true that these will require a GOOD motor and impeller. I'd be scared of a plastic impeller knowing the forces that goes into it...

IMHO, we should all have one if we cut the dirty stuff (foam, mdf, dusty plastics). Life is too great to mess it up!

I totally agree we all should have one, I do not know why i waited so long to make one, It controls the dust like you would not believe.
