I occasionally cut 1.2mm stainless on the plasma cutter, detailed stuff like plaques with letters and numbers etc, the cut is always very slightly rough and needs finishing work.
Used to use a steel cup brush until i started looking into steel pollution causing premature rusting and staining, now i use a stainless cup brush and all finishing tools are stainless-only use.
This is where the problem comes in - working from the reverse side, i find a good seeing too with the cup brush gets into the detail and leaves a nice finish plus it removes any small amount of dross there sometimes is if its very detailed.
However since changing to a stainless brush I have had two expensive foo-bar moments where the brush has sucked up the work and wrecked it, one incident was a sobering lesson and could have been very nasty if the 1m long artwork had jammed on the cup and spun instead of just wrapping up with the cup spinning inside the tangled mess, i had to cut the grinder out of it.
My theory is that the stainless bristle on stainless sheet is 'sticky' as stainless on stainless can be, and is causing the wrap-ups.
So being bothered by the near miss, i tried hitting it with a fine disc - this removed the light dross but naturally did not get into the detail at all, as expected.
I'm looking for something safer than a cup-brush now, would the scotch-brite type pads get in there or just get shredded? I'm sure there are ideal ways of doing what i need, just need to find one
