Okay, we have some people saying that they are balsa/mahogany and some saying that they are maple/mahogany.
Can anyone point me to a source that says definativly what they ware made of? I can't see how balsa would deform when laminated with mahogany. Zach |

QUOTE 76911S Registered User Join Date: Jul 2004 Location: Columbus, Ohio Posts: 201 Hi all, I do still make them but they are sold exclusively here http://www.tremotorsports.com/product.cfm?Node=10299 Epoxy coating them would be fine but that was not the way the original ones where finished and the oils from our hands create a great patina after awhile. All the original 917, 907's & 908's used these and the ones I have seen all have a nice worn used look. You can't really say the originals where made with Birch or Balsa because the restoration gurus don't even know for sure what woods where used. I have sold knobs to both Carl Thompson & Dale Miller for use in restoration projects so these seem to be as close as anyone has found to original. All though, original is not always the best... Mark.. From messing with model airplanes as a kid, balsa wood is so soft it would probably split apart while machining and that would be really frustrating learnig curve. |

The 917 Shift Knob is actually made from turned Birch Plywood. How do I know his. Hans Metzger told me. Balsa would absorb moisture like a sponge and crack as it is very porous. The shift knob was never intended to be light weight. The purpose of the wood was because the linkage transmitted so much heat from the transmission into the drivers hand that wood was used as an insulator.

I got 2 of them from Mark Cross when he was making them several years back...He may still be making them, I don't know. I'll take pictures and measurements of mine later today if you would like. The link to the 911S registry story is: http://www.early911sregistry.org/forum/sho...ight=shift+knob His email was (is?) macross860@columbus.rr.com David |

I got one of Mark Cross' knobs back when he sold them for like $35. Here is a pic. ![]() They weren't balsa. Here is his post from when he was selling them. It might say what he made them out of. I didn't review it. http://www.914world.com/bbs2/index.php?sho...&pid=248306 |

How did you get it on he Rennshift? That looks great. You know, I was able to find a factory Porsche crush sleeve. I tried to use it, but it took more pressure than I was comfortable putting on that wood shift knob. If I would have split that knob putting it on the shifter, I would hate myself. So, I cheated and I just used duct tape to act as a bushing between the shifter and the knob. Wrapped the shifter with the duct tape, pressed the knob on. Its a dirty secret but it worked. Consider that a "Duct tape confession". |

On the TRE site they say to glue the knob on to the shifter arm.

Although I saw this thread I never looked at it, to me who would want a knob made of balsa. Too soft and would look like crap in no time.
Also it has to be to hardwoods, as a softwood and a hardwood would be hard to machine and almost imposable to sand. The softwood will sand more than the hardwood making it rippled. Birch ply could be correct as the Germans loved to use Baltic birch ply. QUOTE Purple heart and Cocobolo Now that peeks my interest...and I have a huge board of purple heart. How about purple heart and black walnut or cherry (IMG:style_emoticons/default/idea.gif) Maybe purple heart and white ash (IMG:style_emoticons/default/idea.gif) |

I thought the big board was purple heart, but now that I've looked it's more likely Pernambuco and I do have some pieces of amazon rosewood

Well, I bought enough mahogany and maple to make 3 or 4 knobs.
I could not find birch plywood - but I did not look too hard. So, I guess the idea of the "balsa" shift knob is just a well accepted myth? Zach |

Mahogany and maple glue up.
in trimmed specs are about 47mm tall x 50mm wide. Starting with 5 of them. I have enough mahogany for 1 more knob, and enough maple for 2 or three. But I am out of clamps and got tired of cutting disks. So, starting with 5. Pics! (IMG:http://farm4.static.flickr.com/3470/3223139205_d5838a0db9.jpg) (IMG:http://farm4.static.flickr.com/3495/3223996290_e19d48ea50.jpg) I'm at the in-laws this weekend due to the house flood, so I only brough hand tools with me. Was really relaxing to slow down and just use a coping saw for a while. I'll leave them in the clamps over night and start turning next week some time. Zach |

Next weekend. I may be able to sell a few of these at Hershey to recover some of the money spent on the house this and next week. Sides, while I'm at the inlaws, not a lot of car work I can be doing. Zach |
