Test fit of curved segments together with a constrained layer damping sheet:
Not yet attached ...
CLD (Constrained Layer Damping) curved segment:
Ribs are modified so they fit together better:
Priming the bitumen:
Front baffle stoppers - these hold the ribs into position firmly.
Vibration damping applied to the internal surface of the front baffle.
First layer of bitumen over primed MDF:
Top walls clamped whilst the glue sets, bitumen applied also. Masking tape is there to keep the bitumen off the middle, where a dowell will be used as bracing.
First layer of bitumen over the first assembled CLD composite segment:
All layers of bitumen applied:
