“It's nice to know that I have a good source for quality guitar wood as well as guitar parts fabrication, such as LMI's fingerboard slotting service. As I am only set up to slot 650mm fingerboards, you guys have saved my butt on making me several odd scale lengths recently! I want you to know that I appreciate you guys and the wood and services that you supply to me, a small, independent luthier. Your fine fingerboard slotting service saves me a lot of time and trouble, for which I am grateful. THANK YOU!"

O'BRIEN NECK JOINT JIG Robbie O'Brien has designed this easy to use neck joint jig to determine your neck angle and then route either a dovetail or straight mortise and tenon neck joint. This jig kit comes with all the assembly hardware, a straight or dovetail mortise and tenon template set (your choice), and a 5 page CAD plan – all you supply is the wood!
The video/article links (below) fully illustrate how to assemble/use the jig and have many helpful hints for making easy work of this often difficult task. LMI MORTISE AND TENON TEMPLATES The LMI mortise and tenon templates (SPMTS, SPMTD) are designed to be used with the O'Brien Neck Joint Jig, but they can also be used separately. They are manufactured from 1/4 inch mdf to keep the price reasonable. If you expect to use these templates more than a few times in your shop, we recommend flooding the adjustment slots with cyano-acrylate glue to harden them a bit and prolong the life of the jig.
You need to use a 5/8 inch OD router guide bushing when using these templates. Sets of guide bushings can typically be purchased wherever routers are sold. Our 3/8 inch bit (SPRB38) works well for hogging out the material on a dovetail–then you can follow with the 7 degree dovetail bit (SP7DT). Use the 1/2 inch straight bit (SPRB12) for use with the straight mortise and tenon template.
Router bits are not included with the kit.
The dimensions of the mortise and tenon prior to fitting them are:
Mortise - 7/8" (.875")
Tenon - 15/16" (.938") The tenon is slightly oversized so you can remove just a bit of material and get a perfect fit.
PLEASE NOTE: The dovetail mortise and tenon templates are different lengths to accommodate the offset created by the template guide when routing the dovetail mortise. __________________________ MORE NECK JOINT JIG INFO:
