Is there any reason you couldn't use delrin rod to make an entire pipe stem as opposed to using it just for the tenon?

Oh, to be more specific, I don't think Delrin holds a bend. That may not be the right reason, but over in the pipe making community it's certainly been thought of and denied for at least one good reason.

This is a very useful run down of alternative stem materials Kurt Huhn posted on pipemakersforum:

horn: smells like shit; not easy to drill or shape; can be brittle; can also be very susceptible to moisture and heat; needs tenon made from other material
wood: easy to shape and sand; longer lengths a pain to drill with tapered bit due to 'grain wander'; pain to bend; prone to cracking due to moisture cycle from smoking; button end can get icky if clenched
Delrin: too soft; feels odd; won't polish well; won't hold a bend
ABS: pain the ass to machine and shape; polishes well; somewhere between acrylic and ebonite in feel
Ultem: cast iron b****h to machine and shape; doesn't bend well but holds it if you manage it; polishes well
polyester: shapes and polishes well; drills like a dream; may overheat during sanding, most varieties won't hold a bend for very long (though some will); brittle and can crack during filing or if bitten
acrylic/acrylester/'pen blanks': pain in the ass to shape; sands and polishes well; prone to overheating during sanding and polishing; pain in the ass to drill; customers may complain it feels all wrong on their teeth
Garolite G10/G11: horrifyingly unhealthy dust; does not polish well; destroys sandpaper, uncomfortable in teeth
carbon fiber: horrifyingly unhealthy dust; polishes well; destroys sandpaper; uncomfortable in teeth
vulcanite: softer version of ebonite used in premold stems; higher sulfur content means faster oxidation; sands, drills, and polishes welll
ebonite: drills, machines, sands, and polishes like a dream; apparently stinky
