Position Dots In The Side Of The Fretboard. The Material If Available From Luthier Supply Houses In Long Sticks. Just Drill The Proper Sized Hole And Trim and Sand The Dots Flush.

Although Reinforcement (Both Static And Adjustable) Is Not Necessary For A Ukulele, I Still Prefer To Use A Laminated Neck, With Contrasting Wood Down The Center Of The Neck For Additional Strength And Added Appearance.

Most Ukulele Necks Are Built From A Single Slab Of Wood. You Can Elect To Use Laminated Blocks And A Scarf Joint At The Head To Introduce More Strength To The Neck And Save A Lot Of Wood.

Less Expensive Ukulele's Utilize East Indian Rosewood For Both The Fretboard And The Bridge. More Expensive And Additional Durability Is Available By Using Ebony, But With The Growing Rarity Of This Wood, Supplemental Woods Are Being Considered.

Use Bone Or Ivory Nut Materials For The Best Tone.

Drill These Holes Only After You Have Purchased Your Tuning Machines. Make Holes Slightly Larger Than The Post Dia. Drill These Holes First To Minimize Tear-Out Of The Tuner Slots. The Top Trim For The Headstock Is Traditionally Made From The Same Wood As The Back And Sides. It is Usually Leftover Stock And Is About 2mm Thick. Glue Maple Or Maple/Ebony Veneer Beneath For Additional Detail - This Is A Personal Preference. Glue These Pieces Before Any Headstock Work Is Started.

The Neck Thickness Varies Quite A Bit From One Ukulele To Another. Typically A Thinner Neck Is Faster, In That It Plays Easier - The Tradeoff Is That A Thin Neck Is Weaker And Is More Likely To Give You Neck Warpage Issues Than A Thicker Neck.

Often The Coped Ends Of The Top And Back Braces Are Cut Through The Ukulele Sides. Make Sure Your Purfling For The Top And Bottom Plates Will Cover This Channel Adequately Though.

To Cover Up The Center Seam Inside The Ukulele Body And Give The Joint Additional Strength Use A Strip Of Maple 1mm Thick. Run Between The Braces And Round-Off As Shown. The Best Way To Install This Is As One Long Piece And Carefully Cut And Chisel Out The Channels For The Back Braces.
