I hate filing and sanding. I do my best to pre fit every thing so I
don’t have to remove so much metal.
I’m not a big fan of using abrasive rubber wheels on solder seams.
They tend to drag out pits and can leave an uneven surface.
I’d much rather use the little snap on sanding discs. The plastic
ones are my favs. They don’t drag seams out the way rubber wheels do.
Remember to only file or grind down 80% then hand emery the rest. If
you file the seam all the way out and then go to emery before
polishing you will have a thin spot.
Have fun and make lots of jewelry.
