“Dear Sir,
A few months ago I placed my first order with you and built my very first guitar. Ovangkol back and sides with sitka top.
I have been a craftsman for a number of years, rebuilding antique pianos, including making new soundboards and bridges, and decided to try my hand at guitars after buying a Taylor 814ce.
The results of my first attempt were surprising, to me and to others. Since I'm a bit "old-school" I built it entirey by hand, no table saw, router, joiner etc. (I did use a driss press!). I have already received requests for custom made guitars, and from a store interested in selling them.
It really helped to find quality supplies, all in one place, so I could start this experiment - which may just turn out to be my next and final career.
Many Thanks.
ps. I have just placed a second order so I can start making a few more......”

Pre-Carved Mahogany Bolt-on Necks, Pre-drilled



HomepageVIDEOtipsRed75See LMI Pre-Carved and
Semi-carved Necks video
with Robert O'Brien.


Our pre-carved necks are CNC'd (computer numerically controlled router) from quartersawn Honduran Mahogany. The guitar necks feature an oversized peghead which allows the builder to customize their peghead shape. The neck/heel has a straight mortise/tenon which is pre-drilled for either a Martin™ D-style or a Martin™ OM-style configuration. Brass inserts are pre-installed in the neck and the rest of the hardware needed for bolt-on installation is included.

Most necks are available with or without a Diamond at the peghead base. The diamond is decorative, but also adds a bit of mass at a structurally weaker section of the neck. It can be easily removed if it is not desired.

Our 12 fret slot head necks have a peghead that is finished very close to final dimensions. This is a good neck to use for Parlor or other small steel string instruments. Like our 14 fret necks, brass inserts are pre-installed in the neck and the rest of the hardware needed for bolt-on installation is included. These come with a diamond at the peghead base which can be removed if it is not desired.

Note: Our 24.9" neck is for a 12 fret to the body guitar, but the nut placement should be the same.

Each neck has a 1/4" x 3/8" truss rod slot cut to accommodate our double action truss rods.

  • All 14 fret to the body, 25.4" scale necks use the TRSD truss rod.
  • All 14 fret to the body, 24.9" scale necks use the TRSDA truss rod.
  • All 12 fret to the body, 24.9" scale necks use the TRSDS truss rod.

Note: If you are ordering our pre-carved, slot-head neck to use in conjunction with the PL29 parlor guitar plan, please be aware of the following: Our PL29 plan features a guitar with 24.5" scale and the pre-carved neck that we offer is a 24.9" scale neck. As on the old Martin O-shaped guitars, many of the small sized guitars being made today (Goodall, Santa Cruz, Charles Hoffman) use a longer scale length. Doing so locates the bridge nearer the center of the soundboard, thus "sweetening" the sound. Be sure that you place the bridge (and bridge plate) according to the 24.9" scale length on your guitar and not according the placement shown on the plan!
