Machine Sanding Flat Surfaces Systematically

right the fastest way that I found to be able to do this is with the 10 mm right the 10 mm is nice because it keeps me up above the wood if I bump the sander into the wood I don't do any damage versus the 5 mm and this the 5 mm is is fine on flights but this is just a better situation for the 10 mil but what we want to do is we want to sand the 10 mil and with a a painted door you want to start with a a fine right we want to start around a 220 grit 180 to 220 grit scratch and the reason being is a factory cabinet usually has a clear coat on over the the paint so we're going to again we need to take that back down we need to get that shiny surface look off of it and we need to put a scratch in it so that our next coat will adhere so with this one I'm going to go with the 10 mm fine I can do both the center panel and the rails and styles with this right right so I'll just sand [Music] this so I saw um you do like kind of a specific pattern you went around the square and you went side to side and worked your way up I mean is that best to do can I just randomly sand around or you can randomly sand around the reason I do what I do is because I want to follow that pattern because I want to make sure I don't miss a spot right so if I follow that pattern I know I'm going to hit that spot um you know and and same thing with the rails and styles and when we're sanding on on raw wood when we're in a factory um you know we are looking to take out cross grain and so it it's trained into my mind now to make that pass around the racetrack and so so we call it we'll go around the racetrack a couple of times and concentrate on the the cross grain right
