Hi all, I recently set up a dust extraction automation system in the workshop at Science World (where I work), and it has been kick-ass having it. I’m excited to build a system like that for VHS!
The main info I need is which tools we’ll want to connect to the system. Things like the table saw, thickness sander, router table, and anything else that produces large amounts of wood dust are good candidates.
The system at Science World is centred around a control panel containing a Programmable Logic Controller to which multiple current sensors connect to. These current sensors are built into short extension cords to which each tool is connected, although wireless could be another option. The PLC uses the signals from the current sensors to turn on the dust extractor with a contactor/relay, and shut off the dust extractor about 10 seconds after all tools have been turned off (this short delay helps make sure the dust makes it all the way through the ducts into the dust extractor itself).
Anyway, I’ll take care of this project, but we should think about how we’re going to set up the actual ducting for this system.
P.S. I have a 2hp dust extractor blower that I plan to donate to the space as part of this.
