Truss rod installation. These truss rods should be installed flat side facing the fingerboard (round rod at bottom of slot) with a filler strip over them. Installing a filler strip greatly reduces the  possibility of a truss rod rattle and reduces the amount of backlash in the rod. My installation procedure goes like this: Mill a 1/4"  wide, flat bottom slot in the neck that is at least .400"  deep. Make a filler strip approximately 3/16"  thick that snuggly fits the truss rod slot. Rough up the flat backbone of the rod with very course sand paper or a file. This creates a good gluing surface. Put the rod in the slot with no glue. Apply epoxy to three sides of the filler and press it into place over the rod. Don't overdo it with the glue. You don't want it to squeeze down and foul up the threads.




UPDATED RODS, Pat. (9/19/2013)

Now, all stainless steel, longer end block, more thread!

Mark Blanchard came up with some clever improvements to our standard rod, which is all  stainless steel, and a unique thread arrangement to make this a precision, smooth-turning, low-torque rod. Turn the nut on the new rod 6 times to achieve the same degree of adjustment as one turn of the old rod! We think it may be the best rod on the market.


 Apply LIGHT clamping pressure along the length of the rod (see photo). You want enough pressure to eliminate any space between the flat bar and the round bar, but not so much that it makes the rod hard to turn. Check the resistance by turning the rod a quarter turn in each direction. You will notice that the filler strip will sink in a little more in the middle than at the ends. After the glue dries, level off the protruding filler strip. Avoid turning the truss rod more than 1/2 turn until after the fingerboard is glued on and fully dry. 

This rod has become a standard in the industry because of its true 2-way adjustment capabilities. The keyway on the working end of the rod takes a long-shanked 9/64"  Allen wrench. When it's turned one way the rod turns one way. When it's turned the other direction the rod turns the other direction. Amazing!  Because this type of rod can be installed so that it can be adjusted from either the peghead or through the soundhole, and because very little wood need be removed from the neck when routing out the channel, this rod is probably the most popular rod on the market. This is a rod based on the best features of several rods that we developed at The Luthier's Mercantile from a design that Jeff Traugott showed us. We take it a step further here by using stainless steel and chrome plating parts of it so it doesn't rust a few years down the road. Includes heat shrink plastic to guard against "rod rattle," and comes with 9/64"  long-shanked Allen wrench. We have this rod made in China under the supervision of a US guitar builder and the quality is excellent. Note that indicated length does not include the 1"  adjustment nut.





Note graphic above: we do test the rods before we send them out. We have shipped many thousands of these with only a handful of problems. (In 2011 we did receive a bad batch, and there may be a few still floating around that we didn't catch.) We STRONGLY SUGGEST YOU TEST THE ROD before you install them. Make sure that you rotate the nut and not pry it when testing (or when adjusting). Give the rod a rigorous test. If the rod does break in the neck, all we can do is replace the rod; we cannot compensate for more than that.  If you are able to "bury" the adjustment nut in the neck, i.e., allow access to the broach while containing the nut in the surrounding neck wood, prying is then prevented.

We suggest using a filler strip (mahogany for example) to prevent "rod rattle." This also takes up backlash in the rod.
