Product Information

This is a set of 3 brass wedges for aligning the inner slide of a Trombone with the cork barrel. Each of the 3 sections has identical scribed reference marks to aid in perfect alignment of the inside tube to the cork barrel.

The key when working on Trombone slides is alignment - this is especially important when adjusting the position of, or replacing an inner slide tube. There are so many factors to consider to achieve a perfectly smooth running slide. Minor discrepancies can cause fundamental issues which will keep you going round in circles looking for the fault.

Thankfully, there are a number of tools which help to eliminate the guesswork. The G35 set of inner slide leg spacers from Ferrees are excellent in this situation. These small wedges of brass are a simple but brilliant method of aligning the slide tube centrally in the cork barrel. 

Place them into the gap between the inner leg tube and the inside edges of the cork barrel, with equal spacing. They can then be tapped in evenly and gently, ensuring the scribed markings on the spacers line up. We suggest using the F11 canvas mallet for this job as it's very precise.

You can tap the spacers gently in and out until they're completely even, secure and holding the tube perfectly central. They can stay in place while you solder the leg into position, then simply tap them out when you're finished.
