Got 2' of Delrin rod from McMaster.



Drilled, tapped, and chucked.



My first attempt.



Fits and shifts nicely.



Got bored and made another one.


They work nicely. I just tapped the Delrin - didn't use a threaded insert, so we'll see how long they last. Speak of tapping them, I'm doing something wrong - the holes are not centered, which is odd, I figured turning off the run-out would auto-center them...

Got a foot of Delrin left over. Anyone want a bespoke shift knob? Let's see, to cover my costs and my time in making one, I'd need $100 at least - only twice what they cost online

 

Looks really nice!!! I like the smooth one

 

Ribbed for her pleasure FTW!

 

CUSTOM!!!

Looks good Voytec!

 

that's pretty sweet, nice work man
i like the ribbed version

 

Great idea. Delrin should be cooler to the touch on those hot days than the aluminum knobs a lot of us have.

 

that is sweet. my old man runs a machine shop and they use all that high end titanium. i wonder if i could get him to make me one like so...

 

could you make a counter sunk knob. something that sits crazy low and is spherical like the cr knob just sits lower?? if so, id probly buy one

 

Dildo

 

I made another one that sits considerably lower (but it's longer, so total height remains the same). Countersinking isn't easy, because that tap I have is not very long.
