After a few hours over several days searching I've decided to post up for some advice on this. How are you more experienced makers finishing the flats of your blades prior to installing pinned bolsters and hollow grinding? I can get a bright finish if I go through the grits, taking my time and getting all the scratches out and then buffing. However, I am having some nasty ripples and gouges that although smooth, look pretty nasty when you view at a low angle or from the end of the blade down the face of it. Usually takes some reflection of the overhead shop lights to show up really good. MS paint art included of the location and direction of these. Are you using a 9" or 12" disc, or drawing the blade across the 2" flat platen on your grinders? I'm using the latter method, and it seems any combination of speed and pressure still is causing some problems. I'm betting this is operator error but any advice would be welcome. Thanks!
