Don’t oversand the veneer
The back and sides are laminted with mahogany veneer . 
They’re quite smooth to begin with, and don’t require much 
sanding . If you were to sand unnecessarily deep, you might 
reach wood that’s near the glue under the veneer . This could 
produce uneven results when staining . This doesn’t apply 
to the top wood, which is solid mahogany .

Raise the grain by damp sanding
Sandpaper cuts away the fuzzy fibers of wood grain . Sanding 
causes some of these fibers to lay down flat, even though 
they haven’t been removed .  When wet finish touches them, 
the fibers lift up and make your finish feel rough . 

Solve this problem by raising the grain with a damp rag .  
When you’re done with the 180-grit sanding, wipe the wood 
with a rag that’s been dipped in water and squeezed-out, 
leaving it just damp . After the wood dries, you’ll feel the 
roughness of the raised grain . 

Sand with 220-grit
Now move on to sanding with 220-grit, which cuts away the 
fibers raised by the damp rag . Completely sand the body and 
neck . After sanding with 220, the wood is ready for finish . 

Before finishing, you need to establish the bridge location in 
order to tape off the area where it will be glued later . 

 

Locate the bridge 

A dowel makes good block for sanding the waist .

Sand to make sharp edges slightly rounded .

The bridge needs to be at the correct distance from the 
string nut for your uke to play in tune . We’ve made locating 
the bridge very simple: you just  need one measurement . 

Dry-fit the neck onto the body using one of the neck joint 
dowels . With a straightedge down the middle of the fret-
board, find the center point on the tail of the uke . Mark this 
on a piece of tape . 

Measure carefully along this centerline to locate the bridge .  
Start from the end of the fretboard where it will contact the 
nut, and locate the distance indicated in the drawing below, 
depending on the size of your uke . 

This is the distance from the nut to the front edge of the 
bridge, not the distance to the bridge saddle .

Use a piece of tape to mark this location on the uke . The tape 
should be longer than the width of the bridge . With your 
straightedge, mark the centerline on this tape . 

Center the neck
Check to see if the neck is centered . Place the straightedge 
along both sides of the fretboard and mark the tape at the 
bridge location . These two marks should equally straddle the 
centerline that you’ve already marked . If they’re off-center, 
shift the neck until it’s centered . 

Measure from the front of the nut to the

front of the bridge (not the saddle)
