"grits and grunts" here in Florida. Grunt is a saltwater fish we catch in the Gulf of Mexico, I like my grits with cheese and butter. I have used 36 grit belts to grind limb edges but usually use a 50 to get 1/16" from line then use a 120 to grind to the line. 120 will leave a cleaner edge over the 50, I still use 180 or 220 grit on my mouse sander to further smooth the limb edges. During limb grinding I keep a sanding block with 80 or 100 grit to keep masking tape on back trimmed even with the sanded limb, the tape can roll up a little and be wider than the glass..
