This is only free if you have material, which I got from the scrap pile from work.
I used a 5" by 1.5" wide round piece of aluminum

[/img
Then I put it on the mill. Used a 3/8" mill bit to smooth it out. Could use a grinder, but again I had the resources so I used them
[img
I designed a shift pattern on it to kind of customize it. Used a 1/2" bit. Also I made the reverse slot over 1/8" wider to distinguish a pattern.
[/img
Now I got the basic shape of any shift knob. So I drilled out the bottom hole to .344" drillbit. That is the correct size for a m10x1.5 tap. It's best to do it on a lathe so its perfectly centered, which is what I did
[img
Just a quick polish with sand paper and scotch brite pad to see what I got.
[/img
Now let's get to the lathe. My favorite part. Just took it down nice and slow. Take your time here
[img
Once your happy with the shape, hack it off. Cut mine lower to leave room to round it off.
[/img
Once I cut it I realised it wasn't drilled out deep enough. So I had to drill it out more. I worried about putting marks in it from the vise so I put 'fish paper' between them.
[img
Tap it with a m10x1.5 tap (standard Honda thread)
[/img
Quick polish again and you're done! Then test fit on car, and enjoy!
[img
[/img
This is the first thing I ever made for a car. I never used a lathe either. So its not the greatest but it was fun and definitely a learning experience. Did this to show you don't need to buy everything, can reuse things laying around to make something one off.
