Technical Flugel Horn Maintenance | Brass Toff Lowton

Leave a Comment / Flugel Horn / /

Mechanical failure in the flugel horn often results from internal calcification and the accumulation of organic debris within the conical bore. Unlike the cylindrical sections of other brass instruments, the specific geometry of this instrument facilitates moisture retention, leading to oxidation and localized corrosion. At our Lowton facility, we utilize ultrasonic cleaning to remove calcium […]

Conn 88H Bell Restoration: Precision Mandrel Reshaping and Mechanical Analysis

Leave a Comment / Trombone / /

The Conn 88H trombone arrived with a significant structural deformation in the rose brass bell section, specifically located prior to the flare. A high-impact collision had compressed the wall thickness and compromised the internal geometry. Such physical trauma introduces resistance to the air column and disrupts the standing wave essential for acoustic projection. In our

Technical Baritone Leadpipe Fabrication and Bore Alignment

Leave a Comment / Baritone / /

The arrival of a Bb baritone at our Lowton facility without its leadpipe presents a total disruption of the acoustic column. Without this critical entry point, the instrument functions as a series of disconnected resonators rather than a coherent pneumatic system. At Elliott Brass, we treat these structural failures with mechanical precision. The leadpipe is

Tuba and Euphonium Repair: Mechanical Tolerances and Dent Removal Physics

Leave a Comment / Euphonium / /

Repair work often commences not with structural damage, but with the systematic removal of performance-degrading debris. The accumulation of calcified deposits and metallic particulates within the bore of a professional euphonium acts as a volumetric restriction, disrupting the laminar flow of the air column. This internal fouling creates an acoustic boundary layer perturbation, effectively shrinking

Conn 88H Restoration: Analyzing Deformation and Tolerances in Vintage Brass Repair

Leave a Comment / Trombone / /

The assessment of this Conn 88H trombone revealed severe plastic deformation across the bell flare and slide crook. Initial mechanical integrity checks indicated that internal bore alignment was compromised by localized impacts. Before addressing the geometry, standard procedure involved ultrasonic cleaning to eliminate internal calcification deposits and organic residue. These deposits, acting as internal friction

Vintage Brass Restoration: The Imperial Baritone Rescue

Leave a Comment / Baritone / /

We recently undertook a formidable restoration challenge: a classic Boosey & Hawkes Imperial Baritone Horn that presented significant cosmetic and structural compromise. These vintage instruments are revered for their tonal quality and robust build, yet decades of active use can leave them heavily scarred. This particular horn arrived with severe trauma, exhibiting deep indentations and

Extreme Brass Damage: Challenging Baritone Repairs Accepted

Leave a Comment / Baritone / /

In the technical domain of brass instrument restoration, there exists a threshold where routine dent work transitions into catastrophic structural repair. We recognize that incidents—from severe drops causing major bracing failure to low-velocity traffic impacts (the dreaded ‘run over’)—can compress a Baritone beyond what most conventional shops are equipped or willing to handle. When a
