On my torchmate I have a water table, fume extractor and a fan.
So on the side below the rail i had my brother (who does hvac) bent up some thin duck work and I glued a flange to it hooked up to a ace industrial fume extractor. Above the table I have a fan (harbor freight dust collector) and drilled a hole to blow outside and made a clamp that attaches to the gantry
Sadly the motors on the fume extractor died and I need to replace them and the fan took a crap too. Probably because I don’t have a filter on the fan
I can get pics if interested
