Step 6. Determine the Bridge Position The bridge must be exactly placed on the body of your ukulele. This is to guarantee correct intonation of your completed instrument given its scale length. The correct bridge position for your kit places the middle of the saddle at exactly 348mm (± 0.5mm) from the front edge of the nut. The front edge of the nut is the edge closest to the fret-board and represents the point where the strings leave the nut to travel down the fretboard to the bridge. Measure this distance (348mm ± 0.5mm) from the front edge of your nut and mark a faint line on the body. If you can avoid writing directly on the body of the ukulele, it is a good idea. Place apiece of painters tape across the body in roughly the correct location and draw on that. Note When positioning the bridge, the saddle will need to remain exactly on this line for correct intonation of your instrument. Next, using two pieces of cotton or twine, simulate the two outer strings of the ukulele running up the neck. Attach the cotton to the bridge (as you would the ukulele strings, and run them from the bridge up the neck and over the nut. For the purposes of this exercise, the nut can just rest in place at the top of the neck. Tape the ends of the cotton pieces to the headstock so that they are anchored at the correct distance from the bridge. This distance is such
that it allows them to be pulled tight when the saddle is on the line you marked for it. Orient the bridge left-to-right so that the two outside strings sit an equal distance from each edge of the fretboard. When you are satisfied, the bridge can be screwed into place. Take each of the two screws provided and screw the bridge into position. Each screw hole has a circular white cover to hide the screw. This can be glued in place with a drop of superglue if preferred.
