Shape nut, shape saddle, and string up the uke
Do not glue the nut at the top of the neck or saddle into the bridge. Why? It makes changing the action of the strings easy.
Gluing the bridge
Determine your scale length and mark where you want to place your bridge with tape. Scrape off the area where the bridge is going to be glued with a razor, then glue bridge and hold with a bridge clamp. Hold for 24 hours.
Finishing with Tru-oil - Do not rush this process.
Before you add the bridge, sand the whole 'ukulele starting at 80 grit until you get your desired thickness on the soundboard. Be sure to put some pencil marks around the whole body so you know how much material you are removing. Use the following progression of sandpaper, 80, 100, 120, 150, 180 then stop at 220.
Get a damp cloth and wipe the 'ukulele and let dry. There will be little hairs that rise when it dries, sand and repeat process at least twice until you do not feel any more wood hairs after you wipe the uke with a damp cloth.
Now you can progress to 320 and even up to 400 for a smooth finishing surface. You want to make sure that with each progression of sandpaper you remove the scratches from the last sandpaper grit.
Once you reach your desired smoothness, you are ready to add your first coat of finish.
Only apply 2 coats of oil per day. Wipe on then wipe off immediately. Repeat process until you reach your desired shine.
Trimming the soundboard and back
Gluing the back
First dry fit the back by placing it on top of the 'ukulele sides in the same jig used to glue the sides and tentalones, lineup the center points of the back and uke body, then clamp without gluing anything yet.
Once clamped, then uke over and mark the braces where they touch the sides. Unclamp the back then measure the thickness of the tentalones at the point where you made the mark on the back brace bars.
Now the 'ukulele is boxed and we are ready to trim the excess off the sound board and back.
