I have my cabinet built mostly and it's up and running. I'll get some pics up this weekend. In the meantime, working on a solution for the dust extraction. After using for a bit to get a pair of motorcycle wheels finished up for the polisher, I learned that the dust gets worse, the longer your media gets reused. When I first started, it was totally fine, so I didn't worry about it. By the end, and adding in a couple small small rusty steel parts, and it was starting to get pretty choked up.
I had a thought-
I have lots of room, so why not filter the dust before it gets sucked out?? Simple would be a K&N type cone filter added right to the hose outlet. A little more involved, but cheaper, And the added ability for better filtration, would be to add a plenum to the end of my cabinet and fab a mount for better filters like a low micron furnace type filter panel. I know it wouldn't get it all, but by the time it got to the vacuum's filter, the dust would be greatly reduced. It would still all be MUCH cheaper than buying a dedicated extraction system, and would leave my shopvac more easily disconnected and available to be used for it's other intended purposes.
I did build a "water in the bucket" contraption to filter ultra fine dust from sanding cars out of my shopvac, years ago. While it did work, it was quite a mess, and the water got pretty rank. We were using it several times a day and it got nasty. I can only imagine that an "every so often" setup with water in it would grow some really cool science experiment worthy funk.
. I can more easily see myself beating the dust out of filter pleats when needed...
Any thoughts??
