minutes
Date of meeting: 19 May 2000
Present: PSF, BWK, ALL, MS, JHW
1. Mechanics
- Backplate pressing to 3 Tonnes failed to cure the warping. ALL
has sent instruction for machining to allow the side bars to be inserted vertically.
Should be back next week.
- ALL showed a sample of a VPT holder allowing rapid (20 seconds)
insertion of a VPT and connection of flying leads. May need to extend spacer to
allow more room for connectors.
