Step 1. Sanding While the components of your ukulele kit have been shaped and roughly sanded in the factory, to give your instrument the best possible look and feel you will want to sand it further. We recommend that you sand with at least with 180, 240 and 360 grit sandpaper to achieve a desirable finish, and that this is best done to each piece of the ukulele separately before assembly. Depending on your intended wood finish, you may even like to sand the pieces even finer Sanding the Body • Starting with 180 grit sandpaper, sand with the grain until all machining marks have been removed and a consistent scratch pattern has been achieved. All surfaces should be smooth to the touch. Repeat with 240 grit sandpaper, removing all the scratches from the 180 grit paper. Remember to always sand with the grain. Repeat with 360 grit sandpaper, removing all the scratches from the 240 grit paper. All surfaces should now feel beautifully smooth Use a tack cloth or brush to remove all sawdust from the body.
