Free Steel! Oh heck yes!!!
I MiG on mine a lot and get splatter and such. I use old dull grinding disks using a light touch on the grinder to clean the top off without taking off the material on the bench top.
Ya know, it's almost too pretty to weld on
I made my shelves out of expanded metal so all crap from grinding and other dirt falls through. Expanded metal is expensive at the Box stores and usually small anyway. Buying it at a metal supplier much cheaper but the ones around here only sell 4x8 and it's a bit pricey - BUT - there's always a use for it.
I have a couple of vises I use, a low profile one is bolted on but can be removed, I have a couple of other ones I can clamp on and I have Big Bertha that's bolted to a heavy plate - big enough to hold things but not too heavy to move.
