LMI sold my Neck Angle Jig for many years. They used to sell my plans for it with a hardware kit and then they begin making and selling it direct. This jig allows you to dial in the correct neck angle when making either a Mortise and Tenon or Dovetail joint on your instrument. As soon as LMI closed their doors last year I began getting emails asking where to purchase the jig . I pointed folks to my website where the original plans are still available for sale if you want to build your own jig. I am happy to report though, that my neck angle jig is now being manufactured and available for sale at Skyscraperguitars.  This jig has stood the test of time over the last 20 years. I personally have set well over a thousand necks using the jig.  Greg at Skyscraper Guitars and I have now put our heads together to come up with a new and improved version of the jig. Get yours today and make neck setting a lot easier. 
Below is a link to a video I did showing how to use a previous version of this jig. The new and improved version works exactly the same way but addresses some of the issues related to the previous jig.  
 
 
Here is what a user of my neck angle jig said about the jig.

I ended up using the O'Brien neck/dovetail jig on my last guitar and wow - I wish I had it 25 years ago. Best fitting dovetail of my life. Thank you! - Jay in Canada

I am also happy to report that my classical guitar mold is also available at Skyscraper Guitars. This is the same mold that I use in my classes with my students and the same one I show in my Online Classical Guitar Building Course. It allows you to attach the neck using the Spanish heel method with the guitar still in the form. 
 
Skyscraper guitars also have a 6 piece acrylic template set of my classical plans that includes my body shape and bracing pattern, neck side profile and neck carve profile, fretboard, cutaway and headstock templates. 
All pieces are made with 1/4" cast acrylic, laser cut and engraved with information to make your guitar build come to life.

There are also many other products available at Skyscraper Guitars that will make your lutherie journey a lot easier. 
Happy Building!
