“I received my order today and I just wanted to tell you thanks. The wood is exactly what I wanted, absolutely beautiful, the packaging was great and I'm looking forward to buying more from you. I've purchased tonewoods from other vendors and ebay before, but even the best from them doesn't compare to the quality and value of what I bought from you. Thanks again!”
Robbie O'Brien - influenced by many others - came up with the idea for this clever neck alignment and routing jig. The jig is simple but elegant in the way it helps you determine your correct neck angle and then gives you an easy way to transfer the angle to your neck. It also enables you to rout both the mortise and tenon accurately. Only a small amount of fitting is necessary after the routing is done.
The jig comes in an unassembled flatpack, but it is relatively easy to assemble with a minimum of tools and glue. 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 & 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 (SP7DTL). Use the 1/2 inch straight bit (SPRB12) for use with the straight mortise and tenon template.
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.
• Router bits & template guide bushing, sold below, are not included with the Jig/Templates.
