What welding projects are you working on? Are you proud of something you built?
How about posting some pics so other welders can get some ideas?

I don't know how to measure the actual pull at the top of the table. I did do what Jody did in his Youtube video with lighting a paper towel placed at the top of the table. To my delight, all the smoke and fumes were pulled down but as the paper burned and drifted down to the cone, to my horror, I watched all the ash and sparks get blasted out of the end of the fan onto the driveway. Later on I successfully tested the downdraft function with welding flux core wire, I videoed the event and uploaded a screen shot in the first post. I need to test it with stick welding too. I didn't have to wear my respirator but in the future I probably should. Honestly I think this ventilator fan 0.22hp is just barely enough to get by. I've been contemplating removing my 1.5hp blower from my cyclone wood dust collector to use but then again maybe it would pull too hard and blow metal dust onto the driveway. If you want to me try some other tests for the downdraft capability let me know.

Tonight I clamped on some scrap sheet metal pieces from an old Sears radial arm sheet metal stand to help deflect grinding and cutting debris from angle grinding and abrasive saw cuts. Seems to capture 97% of the sparks but the garage really stinks after making a single cut. I think the abrasive blade glue burning makes it smell bad.
Clamped on angled sheet metal deflectors for grinding and cutting.  Helps a lot.
