Propeller Shaft - Stern tube Liner

thingiverse

A custom liner was created for a 6mm stern tube to fit Peter's hull design, which originally called for an 8mm shaft. A visit to the local R/C store revealed that an 8mm stern tube shaft was not available, but a 6mm stern tube and 4mm shaft could be used instead. To make this work, liners were fabricated and placed in the hole, using three pieces per shaft and securing them with Loctite glue. The excess material was then cut away and the 6mm shaft was installed. Inner Diameter: 6.35mm Outer Diameter: 7.8mm
