*O'Brien neck joint routing jig, choose dovetail or straight mortise and tenon

$214.62

Robbie O'Brien came up with this clever neck alignment/routing jig. The jig is simple but elegant as it helps you determine your correct neck angle and then gives you an easy way to transfer the angle to your neck. It enables you to rout the mortise and tenon accurately. Only a small amount of fitting is necessary after routing. 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.

**Router bits/template guides are not included with this tool. One set of templates is included at no additional cost.

  • Template, mortise and tenon, straight (ref: SPMTS)

    The LMI mortise and tenon templates 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" 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.

Product Description

This jig is produced from medium density fiberboard (MDF). 

The SPRB12 straight bit (see below) is recommended for this jig. 

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.

Dovetail mortise and tenon:

Our 3/8" bit SPRB38 works well for hogging out the material on a dovetail–then follow with the 7-degree dovetail bit SP7DTL. These items are recommended below. A small amount of fitting will be necessary after routing to 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.

You need to use a 5/8 inch OD router guide bushing (not included) when using these templates. If you don't already own this item, see below to purchase one from LMI.

Router bits & template guide bushing referenced below are not included with this tool.

Good jig

Went together easily! Would like to see a little better direction on fasteners (Robbie uses a Brad nailer in the vids, but I don’t own one)

I do have some issue on the body side with the knobs coming off the screws for the clamp. I am guessing I am supposed to epoxy these in place so that loosening the clamp doesn’t loosen the knob, but haven’t gotten there yet.

Also, I wonder if a ukulele sized template could be fabbed up? I’ve used this on guitars, but recently started a ukulele build and am working through how I’m going to get the m&t done.

Thanks David. This is the first we have heard of there being a problem with the knobs. Epoxy should take care of it, but let us know if you need replacements. We are looking at ways to use our (mostly guitar-oriented) tools for ukes, but we have addressed this with the neck joint jig yet. -Chris

You MUST buy LMI's special bit!

What is not shown anywhere here is that since the top is 1" MDF, and you need to get 7/8" into your body/neck, you need a daggone long bit. The only place you can find a bit long enough is at LMI. I've spent two weeks trying to get other bits to work, but since you need to be able to plunge to 1 7/8" MINIMUM, I cannot get standard bits to work without having only about 5/16" of the bit in the collet, which is dangerous. LMI really needs to add a disclaimer to this that you need an extra long bit for this thing to even work.

Hi Ronald -Thanks for your feedback and for your orders! We offered the appropriate bit as a convenience not really being aware that it might be hard to find elsewhere.

Awesome!!

The jig went together very easy and the instructions were very clear to follow. I watched the videos on using the jig and felt confident enough to try it first time without a test first. The results were flawless. With just a little sanding I was able to make a very clean dovetail joint with amazing results. The package and contents were delivered with no damage and I live in GA which is a long ways from LMI.

ot all that

I bought this jig expecting it to be as described on the online video and as shown on the O'Brian online lessons that I purchased. It was not even close to what I expected! It is made out of MDF 3/4 materials that swell, and warp quite easily. I have adjusted, and adjusted, had to take it apart, and back together again, adjusted and had very, very poor results. I cannot get the neck to center on the neck side, the hinge was loose and wobbling, so I had to rework that. Never had it work to where I didn't have to spend time fine tuning either the centering of the cuts and the angle of the neck to get the correct measurement at the bridge. DO NOT BUY THIS UNLESS YOU WANT A LOT OF FRUSTRATION. F - grade

John, We are sorry to hear about your frustration. You are welcome to call or email us directly anytime you are having trouble with a product you have purchased from us. We can usually resolve it immediately! That being said, what you encountered with the neck jig is really unusual. This tool has been among our best sellers for years now, with many hundreds sold to customers satisfied with its accuracy, convenience and durability. We are hesitant to change materials (and therefore, increase costs) when the current choices have enjoyed such as a good track record of performance. But we will keep our ears open for any other complaints similar to yours. By the way, in an older video, Robbie does use a plywood version (prototype), but all the other subsequent videos show the MDF version that we sell. -LMI
