Abstract

A system for trimming fins on a downhole tool is disclosed. The system includes a jig that mounts to the shaft of the tool. A linear aperture is formed in the jig and has a closed end, an open end, and is sized to axially receive a single fin of the tool. A channel is located on an underside of the jig beneath the aperture. The channel has an inner radius of curvature. The inner radius of curvature is substantially similar to an outer radius of curvature of the shaft. The channel can form a friction lock on the exterior of the shaft and be removably attached to the shaft without fasteners. The channel is arcuate and has a selected arcuate span.
