It was Halloween season and my son called one evening from a big box store. He was shopping for Halloween candy and ran across a tool to remove the pulp from a pumpkin. Well the apple didn't fall far from the tree. He said, "Dad, I found something you are going to have to try". His thought was this might be a good paper pulping tool. He was right.
Google "Pumpkin Gutter" they are available several places on the internet. Read and follow safety instructions. The tool works great to pulp paper in small batches. I've been using the Gutter it in a 1/4 inch light weight drill and making pulp from well soaked paper has been a breeze.
