Scratch removal #4 SS

admin

I'm working on a job, building a heavy duty kitchen island, with #4 brushed 304 stainless.  Normally I'm real anal when it comes to handling finished materials to avoid this type of issue.  Problem is, our sheet metal brakes couldn't handle the material, so we had to outsource the bends.  Now there are quite a few decent scratches that I need to remove.  What is the best method to remove these scratches and still keep the brushed finish
Reply:One trick that I use sometimes is to sand it smoother than I want the final product to be, and only then sand it with the final finish.   So if I want a 120 grit sanded finish, I might actually sand it with 220 grit to remove all the coarse marks, and then go back and sand with 120 grit, to create a uniform appearance.   3M has a recommended procedure for creating/repairing a #3 or #4 finish.   Their three step process involves leveling the weld, setting the grain, and final finishing.  The touch up is with a hand pad.   The procedure includes specific abrasives and equipment.   You should be able to find it on the web.    I noticed that they use inline sanders, rather than rotating disks, to generate "straight line scratches".I am sure that someone here has personal experience with doing this.RichardSculptures in copper and other metalshttp://www.fergusonsculpture.comSyncrowave 200 Millermatic 211Readywelder spoolgunHypertherm 600 plasma cutterThermal Arc GMS300 Victor OA torchHomemade Blacksmith propane forge
Reply:Kinda depends on the depth of the scratches, but i now a days always cleanup sheets with a burnisher. The traditional brands (metabo, Fein) are very expensive (>$600) but on ebay there is a company that sells the brand hardin. I got one of these and it is build really well. You can pick those up for somewhere in the $60-$120 range brand new in auction setting on ebay.

Reply:Does the Hardin burnisher use the same abrasives as the Metabo or Dynabrade?   What abrasives are available?At least once in my life I bought a tool for which replacement abrasives were not available, and I had to figure out how to modify the tool to take standard abrasives, kind of a pain.RichardSculptures in copper and other metalshttp://www.fergusonsculpture.comSyncrowave 200 Millermatic 211Readywelder spoolgunHypertherm 600 plasma cutterThermal Arc GMS300 Victor OA torchHomemade Blacksmith propane forge
Reply:Dynabrade make a lot of different tools.They call that one a Dynisher.http://www.dynabrade.com/dyn10/produ...acuum=&search=
Reply:A lot of the scratches are deep and actually, my pieces look very similar to the picture above.  The sides didn't get marked up to bad.  Nothing some red scotch brite won't cure.  But the tops are what I'm worried about.  Getting all these scratches out and still having the right finish that will match the rest.
