Stop in for a cup of coffee

Get some cut of wheels and they have these sanding disks that work great. I actually use the ones from harbor freight. They work fine and are cheap. 10 for under $10 The sanding flap wheel things I will find a pic get it in 80 grit, you will not be sorry. Also might want to pick up a cheap face shield, you will be amazed what will fall out. You want to check the arbor size on the grinder the wheels come in different hole sizes.
