Using Delrin Tenons: Difference between revisions

* Slice off a length of delrin approximately the length I need. I usually go about an 1/8" longer just to be sure I can bottom out the tenon in the mortis in the stummel.

* I set the spindle speed to about 1200 RPM to drill delrin. Delrin is extremely stable under heat and pressure, and is self-lubricating. This also mitigates any risk you might have of using too much forward pressure and setting the drill bit off-course.

* I do not face the delrin

* I use a short drill bit, or a jobber drill bit with most of it's length swallowed up in the chuck. This helps prevent the bit from wandering.

* after drilling, I use the tip of a skew chisel to cut 3 or 4 grooves in the delrin where it will be epoxied to the stem material. This is necessary, since delrin will not take adhesives very well.
