Edward: Thank you for your response. I've been a bit late in responding
- ice storm on Wednesday, we are scheduled to have power back on by
Monday.
You raised a number of valid points that I had not considered. I was
really hoping that there might be a consensus response that the chipped
layshaft would probably work.
