PROGRESS!
Okay, my grandfather, who owns the lathe that I was going to turn these on, has been hard to schedule time with. For a 94 year old man, he is busy nearly every day. The other side, though, is that he gets tired very quickly. Its important for me to spend as much time with him as I can, while I can. But, long story short, I had time last night, so I made this without the use of a lathe. I used to do a lot of wood carving, so I carved it. I did most of the shaping with a 1/2 round cheese grater type file, and then chucked it into my drill press for sanding. I raised the grain 3 times, and the last sanding was at 400 grit. It is baby butt smooth. Then I threaded the aluminum shank so I could screw it in to my Rennshifter. it is not *perfectly* round, but it is pretty damn close. I think that I will finish it with some boiled linseed oil, or maybe tung oil. Something that will deepen the color and natural luster of the wood w/o staining it. Pics! I still don't have my good camera. I took this one at my office with a P&S, then fixed the white balance in photoshop. (IMG:http://farm4.static.flickr.com/3098/3271133109_551a3643bc.jpg) This really bad picture was taken with my cell phone. Please excuse its crappyness. (IMG:http://farm4.static.flickr.com/3395/3271142255_bc3796efb2.jpg) Due to the fact that I threaded the shank after I made the knob, I'll need to add a small aluminum spacer between the knob and the shifter, or drill out the first 2 or 3 threads in the shifter. Right now there is a 1/16 inch gap between the ball and the shifter. I did not want to thread the shank before I glued it in place because I was worried about damaging the thread when the shank was chucked into the lathe (or drill press in this case). I am going to make 4 more of these, using the lathe. Again, its more about the time with Pop pop then the need to use the lathe, but learning a new skill is always a plus too. Zach |

Oh! I forgot to add the ball specs.
it turned out (get it, TURNED OUT! HA!) to be 46mm wide by 47mm tall. The ball (and shank, obviously) weighs 39 grams. The turned aluminum knob that I have weighed well over 100 grams, and I thought it was light. My reloading scale only goes to 100 grams, so I don't know exactly how much more the aluminum knob weighed, but it was considerable. Zach |

Nice work. If you want to sell one of the extra ones, I'll take it. I'm converting my red car to side shift and the shifter doesn't have a knob.

I'm not sure what I am going to do with the spares. I know I am going to sell some of them to recoup costs for the project, but I am not sure if I am going to make them all into Rennshift balls, or if I will want to make a jig to turn them for the standard shifter (which I don't think will take the shank). Right now the shank can be used to attach the ball to the lathe with a standard chuck. Without the shank, I'd have to make a special jig to turn them.
I am sure that I will have at least 2 for sale at some point, maybe 4. It depends. Zach |

That is fantastic and a really beautiful looking thing!!
I would love one too - s If you fancy having one residing in the UK please let me know.. (IMG:style_emoticons/default/beerchug.gif) I would really love one of these in the '14 so If you can't manage to save one for me, is there anywhere in the US that manufacturers them?? (I guess not as you are doing it yourself (IMG:style_emoticons/default/laugh.gif) ) |

BLO (sorry, boiled linseed oil......too much time spent on guns these days) will really make that look even better! right now it looks great, but it will for sure bring out the depth in the wood. After that, if your really want to go all out, do some wood wax. It will then make it look super smooth, and feel smooth. It looks really good now as is, but if definetly needs something to finish the bare wood....
now I want one of these! They sure look cool! |

Will it fit my 917? The original knob is wore out.

Maybe you could protect the wood with duct tape and use a little file to remove a little material. Like in the pic, rather than messing with the threads on the shifter.

Eh, I just drilled out the top 2 threads on my Renn Shifter and it worked perfect.
However, for the Mk2 ball, I made a jig to hold the ball in the late. Then, once the ball is done I can bore it out to what ever I need. I took pics, but they are not online yet, so those will have to be posted later. Zach |

Hey Zach, If I am so lucky as to be one of the recipients of one of these I too have the Rennshift and what you did with this is perfect. Your work is awesome on this one and I can't wait to see the others. (IMG:style_emoticons/default/beerchug.gif)
