Using Delrin Tenons: Difference between revisions

The diameter of the Delrin used for the tenon will largely depend on the pipe's final stem and shank diameter. It is critical that your drills match the Delrin you're using, especially with regard to the fit of the tenon in the stummel mortise. Both drills and Delrin very slightly, so some experimentation with speed, feed rate, and different drills, even of the same marked size will result it the best fit. Once you find a good drill, make sure you keep track of it. It may be advantageous to  use a different drill for the stummel than the one used for the stem material.
