I have a 2' diameter by 3/4'' thick aluminum plate that was scrap metal on a recent job that I am trying to use as a small surface plate, welding table. It looks like it was machined before but half of the plate was covered in powdercoat and has some light scratches in the surface. I used paint stripper to get most of the powdercoat off, but now there is a hard line were it ended. I am looking for machine shops in or near Sacramento that have a surface grinder big enough to grind the plate. I have gone to Langils of Power Inn and they said the plate was to big, I have emailed S&S in Roseville and they said the same thing. If I can't have it grinded, does any one have other suggestions to scrape the surface clean without gouging it.
I've included a pic, hope it comes out.
