**NOTES:**

**Nominally dimensioned cable has sharp minor edges and the -0.030mm
cable is bordering on sharp with flashing.**

**As this cable was not cut between samples Nominal ,A,B and C , a 25mm
long sample of each cable should be soldered , cut and sent to Ron
Scanlan at LBNL for metallography.**

**The Keystone angle was low for all samples. Note the angle change as a
function of mid thickness. Future cables can have the rolls ground to an
optimum angle for a particular mid thickness.**
