V-Pro discussion

[Roger Jolly]

Hi Del,
          That figure was a calculated guess, from the pile of racked
plates, and the pile of scrap for remelt, similar in both places. Given the
nature of grey cast, I think the 0.4% claim of Kelly is not believable.
Although the grand rejects is significantly higher than the verticals.
The vertical production has been the bread and butter.
At the Yamaha plant they were quite open about the high reject rate, in
fact almost proud, the figure wsa given in very vague terms. They were
stressing theire QC standards and justifying the price difference, so the
figure could well be inflated.
I  agree with you, Re Kelly, many more of the vertical plates should be
recycled. I think that is one of the reasons that Baldwin is now in the
foundry business.
