Pi-Pilot PVC Pipe Reamer

When you need mythological salvation, look for a "sky pilot."

When you need salvation from a slightly-too-small inside diameter, look for a pi-pilot! (Pipe-pilot. Get it? Anyone?)

This is a guide to keep a spade bit from wandering and chattering while reaming a PVC pipe or fitting (or other soft material with an existing hole) to a larger size.

The included STL files may or may not work for you without adjustment. Your best bet would be to edit the .scad file and generate your own. If you need to fit something other than a 7/8-inch bit, you have no choice at the moment.
