Yeah, you'd have to tape it up to file the tips with a fine file. I don't think sandpaper would do it. Go to Ace Hardware and get a fairly smooth 3 corner file. If you only have a few to smooth up, it won't take a lot of taping and stuff. If you have a shop vac, just cut it on and keep the hose close to where you're filing to help keep the dust out of the motor. Packing rags or paper towels below where you're working should be enough. Hopefully, you scored the free rockers from the dude giving the 318 away.
