Piccolo Trumpet First Slide Trigger.

One of our pro clients wanted a valve slide throw trigger installed on his schilke pic. I manufactured up one for him.
One of the beauties of the piece is that it only has two solder joints and thus can be removed with minimal damage to the finish.
One of the main challenges of this project was aligning the slides. From the factory, the span was set about 0.010'' off between the inner and outer slides. This was to make sure the slide didn't fall out. In order to fix this I had to unsolder the outer slides and removed about 0.007'' from the I.D. at the solder points. This allowed the slide to move freely.
The rest of the project was a full days time of filing, drilling, cutting ,bending , and soldering.

This is the unmodified horn.

 Here is the completed trigger. It has a grenadilla touch piece.

 The Linkage is steel drill rod which has been bent to accommodate the geometry of the trigger.

 Everything was made by hand with the exception of the set screw for the touch piece and the ball joints.
