I'm pretty new on here but I thought I'd throw up a thread about an 8 ball shift knob I just built. I bought an inverted 8 ball (white ball with a black dot) off of a billiards website and transformed it into what I think is a pretty sweet shift knob. After drilling it and fastening a t-nut in it, I cut off the top of the shifter shaft and welded a 5/16-18 stud on top of it so now the knob will thread on instead of being pressed on like the old one. This was a cheap fun weekend project that I think think turned out pretty nicely.
