Cactus! workshop videos are always fun. This one especially so. Combining the motor from a discarded vacuum cleaner with some ingenuity connecting multiple pieces of PVC piping, Cactus! makes a fume extractor for his workshop. There are some clever connections made along the way, as well as a homemade funnel (screenshot below), articulating extractor, CNC’d controller box design (read this and this for more info on this app, shown at ~10:15 in the video below), and a really fun way of tucking away the umbrella inside the extractor when not in use!
Finally! something I should have done a long time ago! How to make a fume extractor for welding, out of scraps and cheap stuff. Your lungs will appreciate it!
You can add a pre-filter/cyclone/whatever and use it as dust collector too!
And yeah, I know the feeling:
