This is the final video on the DIY downdraft table. At least I think it is.
Maybe I will add some gussets to the handle… but maybe not. It seems to work fine and I am not likely to load it up with a 5000 lb plate anyway.
I am working on getting some drawings made and will post them on this page when they are done, but I believe there is plenty of info already in the videos to give someone a jump start in building their own downdraft table.
As I said before, this would be a great project for any welding school. It provides some opportunity to teach about welding fumes, fabrication techniques, distortion, angle calculations… and when you are done, you have a piece of equipment that will come in handy for years to come and make the shop a better and safer work environment.
Best of all, it’s a safety item. More likely to be approved if that’s part of the process.
I made this downdraft table to connect to a Miller Fume extractor. But there are other options.
For example, Northern Tool sells an 8 inch utility fan and flex duct that could be used to exhaust fumes far away from the breathing zone… like out the door.
I tested it out using some paper towels and every bit of smoke got sucked down the table… none escaped.
The Miller fume extractor works better than I had hoped for. It pulls a good enough draw on the table top, that I won’t be worried about cutting anything at all… even galvanized steel (if it pays good enough).
