Need advice for catching grinding "dust"

[Backpayne]

I have metal particles all over my shop from grinding and cutting. I cannot afford a downdraft table, but I do want to build something that will keep most/all of the metal particles in one area. Grinding/cutting outside is not the solution for me.

Any ideas (links/pictures/personal experience) you can share?

Thanks!


P.S. This evening I caught my t-shirt on fire due to sparks from cutoff wheel, legit 6" flames! Scary but funny now!
