I am wanting to build my own custom shifter knob for my CJ7 and maybe in the future, custom knobs for all types of jeeps. I have made my own cnc wood router with 4 axises and I am in the process of designing my own hard wood shifter knob. I was even thinking of possibly using the "Trail Rated" emblem on it. But the problem I am having is finding a universal nut or mounting system for the knob. Even finding the actually thread size of both shifters has proven to be a challenge for me. I am wanting to work out the kinks on a drilled out 8 ball or even over sized dices.....what ever I can find that looks kinda cool. But eventually I'll used hard woods like oak, maple, walnut for my shifter knob. May even use 2 or 3 kinds of woods to give it some character. With possible etching or relief cutting on the shifter knob itself. But once again, without a mounting system I can't really do much. Any ideas?? Has anyone else done this? Does anyone know where I can purchase a universal mounting system? Does anyone know the tread sizes for my cj7 or for that matter the thread size for the shifter/transfer case of all other jeeps?
Thanks guys, I am not sure if a concrete anchor would hold Mickey D, has any one tried this? My fear is that it would work itself loose and make driving more difficult. Thanks Renegade82 for the thread sizes, thats a big help. If anyone has some cool photos of there shifter knobs it would be great to see.
I used 3/8 inch coupling nuts. I drilled the eight ball to an interference fit, cut the coupling nut in half and pressed it into the ball. For insurance I put a little epoxy around the nut before pressing it in. I used a capture nut below the ball to orientate it properly on the shaft of the stick shift.
Thanks mvigo for the site, his work sure looks well done. As for useing copyrighted material mike76cj5, thats not what I was intending to do. I have a few ideas of my own. Most shifter knobs are made out of an acrylic resin or some type of metal. I am after a more natural look, hard/exotic woods. With the use of some inlay or emblem involved or even some carving. I may make the tradition pool ball knobs, lol only cause I may have to buy bulk in the ferrels/adapters. I was even possibly thinking of trying one or two out of river rocks. But I am no where near making shifter knobs for all kinds of vehicles as of now. Just for the CJ/YJ and possible TJ models. I guess it depends if the thread sizes are the same or not.
My shifter knob is a beer tap handle. Solid brass center section with plastic caps on the ends of the "T". Unfortunately it's Schlitz, but hey it works and has for 25 years. Don't have any pictures. I seen some very nice cue ball types at the All Breeds Jeep show.
