Dual action truss rod 440mm

With your truss rod you can adjust the bulging or hollowing of your neck and influence the playability of your instrument. Our truss rods are double adjustable, but there are also truss rods in the market that are only adjustable in one direction.

Preparation
Draw your center line on your neck and measure the start and end points of your truss rod channel. Place the truss rod so that you can also use the head to adjust it and let it stick out beneath your use or place it at the end of your neck.

It is important that your truss rod is tight in the canal. Secure your neck at a height where you can easily work and have a good view. Make sure that you can move freely with the cutter and that nothing is in the way.

Use a router bit in the thickness of your truss rod. Our truss rods are 6mm wide, but always measure your truss rod for milling. The head is thicker, but for this you make room in the canal after milling. You can use a small velvet, a Dremel, or a small chisel

Set the height of your router at the height of your truss rod so that it will fit exactly in the channel. Because the channel must be a straight line, it can be convenient to use a router bit with a bearing guide ring and place a guide on both sides of your channel. For example a straight wood board. Make sure it is longer than the channel, so that you can clamp them without them interfering your router.

Routing the channel
Mill out the channel. Preferably use the vacuum cleaner at your router to prevent too much wood pulp from getting in the way, or even catching fire.

After routing, clean the channel and test whether the truss rod fits. Make room for the head and hex key.

Placing the truss rod
Place your truss rod in the channel with the metal part down. Cover the channel with a single layer of masking tape and cut off excess tape. This prevents glue from getting into your truss rod. Then you can glue your truss rod. Better safe than sorry; test whether the truss rod works well in the channel before you glue it in.
