“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 entirely by hand, no table saw, router, joiner etc. (I did use a drill 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......”

Bolt-On Neck Inserts

 

 

TRUSSRODBoltOnNeckInsertsTNI2at500
TNI2
TRUSSRODBoltOnNeckInsertsUkuleleTNIU2at500
TNIU2 for ukulele neck
Our threaded brass inserts and Allen-head bolts make neck alignment, attachment and removal a breeze. Many of the leading manufacturers and hand builders attach necks to bodies with this system. The machining of the neck is greatly simplified, especially with the neck flush-mounted to the body without the complication of either a dovetail or mortise and tenon joint. The inserts have an aggressive thread to hold in the end grain of the flush-mounted heel or tenon.
 
The TNI2 is for use with acoustic guitars, the TNIU is designed for soprano ukuleles and the TNIU2 for anything larger than a soprano ukulele.

Each TNI2 package contains
:
  • 2 brass inserts - 1/2" long, 1/4" internal thread,
    7/16" O.D., coarse thread
  • 2 bolts (1/4-20, 1 1/4, Allen head)
  • 2 conical Belleville washers - enough for one neck (5/8" O.D., 1/4" I.D.). The Belleville washers compress when the nut is tightened and continue exerting tension, reducing the possibility of the bolt ever loosening.
  • 1 hex nut for driving the inserts.
Each TNIU package contains:
  • 1 brass insert - 3/8" long, #8 internal thread,
    .328" O.D., coarse thread
  • 1 bolt (8-32, 1 1/8, Allen head)
  • 1 flat washer - #8 size, 7/16" O.D.
  • 1 hex nut for driving the inserts.
