Scary stuff this. Figure and smoothness getting better all the time. I'm at my target of 18mm correction but the 50% zones need smoothing. I'm using a 6" star lap to dig out the centre and a 12" star lap to smooth it out.

A metric digital depth gauge should arrive on Wednesday to replace the jerky imperial dial gauge I planned on using. Thousandths of an inch make my head spin. I plan on making a graph comparing calculated to actual zone readings.
