Official Luthiers Forum!

I have seen a few examples of a jig that lay on the fingerboard with a centerline that extends to the body for centering the neck. I did a quick search and did not see any noted as such in the forum.

Can you guys post a picture of what you are using to ensure your neck is centered on the body? I think there is a plexi version from one of our sponsers floating around on the forum too. Bob Benedetto shows a wooden one he made. I could really use one for the neck resets I do plus now this archtop. Dove tail joints seem to be a little more picky than a straight mortise/tenion.

Thank in advance.

My friend Tracy at Luthier Suppliers (Link above) offers a fantastic neck alignment jig that I use on every guitar with great success.

You can see the jig in action here:http://www.luthiersforum.com/forum/viewtopic.php?f=10102&t=15022%22

And here is a picture of mine:

Highly recommended!

I'll totally second the recommendation to get the neck center finder from Luthier Suppliers. First off this is one very cool jig and is very accurate. Also the little stop to locate the bridge is a great feature. I've scribed a line on the bottom of my jig for a 25.4 scale and now setting the bridge location perfectly centered at the correct scale is quick and easy.

This is $$ well spend, and this is coming from a guy who doesn't like to part with it . Actually I was thinking of making my own but this is one of those items that really is better to be purchased as it would take me several hours just to make it not including the material.

3 FOR 3...I also use the Luthiers Supply centering jig. I have added two acrylic pins to the bridge locating attachment that matches the end radii of my saddle and have scribed a line tangent to these pins on the bridge locating attachment representing the front edge of the saddle and a line scribed on the main beam that matches up to my front face of saddle for each of my common scales length. When the lines line up my bridge is perfectly square to the FB. My bridge front is a large radius so I can not use the bridge locator as originally designed but it works great now.

The LT jig is quite cool, but for me, I simply use two rulers, and a mark on the top's centre line near the bridge. One ruler sits along the side of the FB, the other measures from this ruler to the centre mark. Repeat on the other side. After making 80 plus guitars, I can tell from the first measure which way, and how close, the neck is sitting to be centred. Maybe not as fast or as cool, but whats a minute ???

I have & use the Luthiers Supply jig -BUT I also do what Tony does just to add some piece of mind because that's the way I've done it for 30 years!

I love the bridge position slider that comes with the jig!
It's a nice piece & makes life much easier !
I make guitars of varied scales and body designs-this jig helps me to
position bolt on necks-fingerboards on classicals -it's a nice piece!

I'd recommend it to all guitarmakers!
