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 Restoration of a Geneva Trumpet Bell Flare | Brass Toff

Leave a Comment / Trumpet / /

This Geneva trumpet arrived at our Lowton workshop exhibiting structural failure within the bell flare. Diagnostic assessment revealed that the distortion in the brass taper was causing an immediate shift in the instrument’s acoustic impedance. Clients from Widnes often present instruments where internal calcification has further compromised the resonance. The accumulation of calcium carbonate and

Trombone Slide Regulation and Mechanical Repair | Brass Toff

Leave a Comment / Trombone / /

The diagnostic assessment of this Rath trombone revealed significant internal obstruction caused by desiccant lubricant residue and calcium deposits. These contaminants increase the coefficient of friction between the inner slide stockings and the outer slide walls. Clients from Runcorn frequently present instruments where the mechanical action has degraded due to the accumulation of particulate matter

Trumpet Maintenance: Ultrasonic Cleaning and Mechanical Restoration

Leave a Comment / Trumpet / /

Mechanical resistance in a trumpet is frequently the result of internal lumen occlusion or the accumulation of inorganic deposits. Clients from Blackburn often present instruments showing significant calcification within the leadpipe and main tuning slide assembly. In this specific diagnostic case, a physical obstruction was identified and extracted, restoring the necessary cubic volume for proper

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
