Manufacturing
Drawing: Diaphragm Booster Drawing.SLDDRW
Operations:
- Waterjet top face profile
- 2 tabs thickness 0.1
- Tap holes with Lathe
- Turn down diameter and step on lathe
- Mill and tap radial holes with radial indexer
Note: The CAD for the rope guide from McMaster is not exact- wait for the physical part to arrive and machine carefully
Precautions
Waterjet
- Check thickness on Waterjet
- Ensure mass-saving cuts do not interfere with waterjet
