2. Describe your valve repair process for a trumpet.

   • Answer: My process begins with a thorough inspection of the valves, including checking for leaks, wear, and damage to the casings, springs, and pistons. I then disassemble the valves, cleaning each component meticulously. I check for alignment issues and replace worn parts like springs, felts, and pistons as needed. After reassembly, I test the valves for proper function and seal, ensuring smooth operation and air tightness. Finally, I lubricate the valves appropriately.

3. How do you diagnose a leaking valve in a trombone?

   • Answer: I would use a combination of visual inspection, listening for air leaks, and using a leak light. Visually inspecting the valve casings, slide alignment, and the felts helps identify obvious problems. Listening for hissing sounds while the instrument is played helps pinpoint the leak source. A leak light can then be used to confirm and precisely locate the leak.

4. Explain your process for aligning a trombone slide.

   • Answer: I carefully check for any bent or damaged parts of the slide. Then, using specialized tools, I assess the slide's alignment, often utilizing a slide alignment tool. Minor adjustments might involve bending the slide's outer tubing with specific tools and methods to ensure it moves smoothly and doesn't bind. Significant bends might require more specialized techniques or replacement parts. Throughout the process, I meticulously check the slide's movement and ensure it’s both smooth and accurately aligned.

5. What are common problems you encounter with tuba valves?

   • Answer: Common problems with tuba valves include worn or damaged valve pistons, sticking valves due to insufficient lubrication or corrosion, leaking valve casings, and broken valve springs. Larger instruments like tubas often experience increased wear and tear due to their size and the force required to operate the valves.

6. How do you repair a dented brass instrument body?

   • Answer: The approach depends on the dent's size and location. Minor dents can be repaired using specialized tools like hammers and punches to gently coax the metal back into place. For larger dents, I might use a combination of techniques, including internal and external pressure to reshape the dented area. Severe dents might require more advanced techniques, or in some cases, might necessitate the repair or replacement of the dented section.

7. How do you handle lacquer repairs on a brass instrument?

   • Answer: I begin by carefully cleaning the area to be repaired. Small chips or scratches can be filled with lacquer touch-up paint matched to the instrument's finish. Larger areas may require more extensive repair, potentially including sanding and re-lacquering. The repair must be blended seamlessly with the existing lacquer to maintain the instrument's aesthetic appearance.

8. What tools are essential in your repair kit?

   • Answer: My kit includes various specialized tools such as valve reamers and hones, slide alignment tools, dent removal tools (hammers, punches, blocks), various screwdrivers, files, polishing compounds, cleaning cloths, brushes, leak lights, and a variety of valve and slide parts for common makes and models. Beyond that, I have a selection of lacquers, felts and corks.

9. How do you maintain your tools and equipment?

   • Answer: I keep my tools clean and well-organized after each use. I regularly lubricate any moving parts of the tools and ensure they are stored properly to prevent damage. Sharpening tools like files and reamers is a critical part of my maintenance routine. I also regularly inspect the tools to identify any signs of wear or damage that could impact my ability to do the repairs correctly.
