Awww, well, if you're not gonna go into business with this, would you mind detailing the neck staining process?
I think quite a few of us might be tempted to try it.
OK, let's see... As I mentioned before, it is a neck I took off from another bass. Therefore, first step for me was to sand the current finish down. I used a battery-powered delta sander for this job. It was my first choice, as I was going to sand the fretboard too. With the edge of the sanding paper, I could get as close as I had to to the frets without damaging them too much...
For the staining itself I used some wood stain from a hardware store around the corner (remember: I live in Germany). I don't know if it's available anywhere else, but I used CLOU Wasserbeize (Beize = wood stain, and it's water-based). It's a little yellow package with some powder in it, so you have to mix it yourself with warm water.
I bought blue and black for the body and yellow and nut/hazel-brown for the neck. I tested the yellow staining on the heel first and decided the tint was too bold, so I diluted it with water (roughly a 1(color):10(water) ratio, if I remember right).
This looked much better and I applied it (with a sponge) to on side of the neck first (because it was lying on a towel, d'oh) to give it a basic yellow-ish tint. Unfortunately, I did not sand too thorough in the first run: in some areas, the color "vanished" again. So I sanded once more and applied another layer of stain (I'm not sure if that's important or if it affects the result in any way, I'll just mention it).
Then I "vintaged" it further in some areas by adding a small amount of the brown stain
while the yellow stain is still wet, mixed them a little with the sponge to create a transition and that's basically it. Did the same thing to the other side of the neck and then attached it to a hook in the ceiling with a cable fixer (like in picture no. 6) to let it dry.
All of this work was done in my dad's workshop, which is heated and relatively dust-free (because I cleaned up before starting). Give the neck some time to dry completely, then finish it with what ever suits your needs.
Hope this helps! And I hope I didn't forget about too much...
