Testimonials

“I really appreciate the extra mile you guys are going to make sure your customers are satisfied. I have a degree in business and I've studied all that stuff about how companies are doing their best to keep their customer satisfied through marketing and incentives, but I can't think of another company (in any field) that makes me as satisfied as you guys do. I'm sure there are some places that sell materials here in Japan, but even with extra cost of shipping and customs fee, I prefer to buy from LMI, because I can trust LMI's service and quality of materials. No marketing and incentives can match the solid good service and I'm a very happy LMI customer.”

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), a 5 page CAD plan and a DVD – all you supply is the wood! The 4 part in-depth video, fully illustrates how to assemble and use the jig, and has 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. We also suggest you use the templates with a 5/8 inch OD router guide bushing. 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). We recommend 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.
