The first blade had a space of about one inch between the body and the steel blade. It was easy to see that if the paper had any buckles or bulges, it would not maintain a consistent gap under the blade. Placing the blade closer to the body was a vast improvement.
Are you saying the bottom of the well was about 1 inch and that you decreased that distance in the second well?
How did you do the machining on the well? It looks very nice.
For up from the ashes, up from the ashes, grow the roses of success!
