The macor parts arrived and inspected today. These include:
- Macor spacer (drawing:
LIGO_Redesign_Macor_Spacer_Drawing_v4.pdf attached below), quantities: 40
- No defects, damages observed
- Parts are free from grease/ machining fluid
- Wall thickness of 1 mm appear to provide sufficient stiffness to part
- Images of parts:
