There was numerous problems with the previous version 2 of the dust extractor system design. This log documents an attempt to address these and adds an addition type of vacuum integration. 

One of the problems with V2 was the way the fine particulates got collected and the manner of integration. The idea of V2 was to use the fine particulate collector was used to fasten the system together. There was not anything wrong with that method, however the execution was a bit difficult. The major change to this version, V3, was to do a better job at the fastening integration. It was achieved by introducing an inner holding piece sealing the fine particle chamber and attaching the external shell.

Generally the integration of the system is much better with all the functions of the cyclonic dust extraction process more solidly defined. 

• Larger debris collected in a larger volume further away from where the inlet to the main cyclonic chamber is located. 
• The cyclonic chambers function is now separate from every thing else and further redesigns can easily done, say increasing the number of cyclonic cells or their radius.
• Release nuts can now be easily used and there are fewer of them.

Bucket Attachment.

Typically dust extractors are located in wood working spaces with large volume to hold chips of wood. The method of the systems integration allows the system to be mounted on a buckets lid dramatically increasing the volume of the large particle collection, more suitable for outside use.
