Does anyone have the specs for the 917 shift knobs? I am talking about the ones that were laminated wood.
I am looking for: What wood was used in the lamination What are the dimensions How was it attached. I know someone already makes these, and I could just buy one. However, I am interested in learning how to use a wood lathe and my grandfather is going to give me his and all his tooling for it. Instead of just turning eggs until I get the idea of what I am doing, I figured this would be a more useful project to start with. Zach |

Zach, post a picture.
It might be either rosewood or mahogany...gotta see it. You can use either, both will gum up the tools. First thing to learn with a lathe is how to hand sharpen the tools. Its really important to learn this... Rusty does pens..he can walk you through the sharpening process, or I can....dont use a machine, use oil stones, old school. I have tried all the new fangled diamond stuff...oil is better for a razor like sharpness. For the shape, you will have to take pretty precise measurements. Quick and simple to do with a contour gauge, then trace that onto a piece of paper. So, you could take the gauge into a car, get the contour, then trace it on the spot...fold that up and be on your way. Mounting should be similar to the stock on. That is a hole of dimension X and buy a new jam bushing to insert into the base of the knob. Rich |

Neat!
Any chance I could get you to pull some specs off it for me? Maybe some reference photos? I'm not planning on making these to sell (don't want to step on toes) but I'd like to have a better idea of what I am making. Zach Hi Zach.

Rich, I don't have any pictures of the original ones. I don't want to work off the repoped products if I can avoid it. Hence the call for specs and pictures, etc.

Well a balsa shift knob, was made of balsawood (IMG:style_emoticons/default/w00t.gif)
the Porsche Carrera GT has an shift knob in balsa. (IMG:http://www.seriouswheels.com/pics-pqr/Porsche-Carrera-GT-Interior-Console.jpg) 917 version is more "ball"shaped This is the best pic i found from a 917 cockpit (IMG:http://www.porsche917.com.ar/Z917interior01_small.JPG) |

I would be interested in the specs as well. I have also considered making one for myself.
If someone could post a link to whoever makes repro version today, that would be helpful as well. |

Looks like a laminate glue up with 2 types of wood. Balsa is pretty soft. I would think you could use just about any wood you wanted as long as you liked the colors.

I thought it was clear pine and magohany. Balsa is to soft to hold up to the handling. Thomas has one and I'll take a look at it for you Zack.

Zach,
If you make a couple, I'll take one. I have a shifter for the red car that doesn't have a knob. Those 917 knobs look cool. Spoke |

Maple and mahogany.
1/8 inch maple 1/4 inch mahogany. Hint. Make a long laminated glue up that is 1.5 wide (if thats the width) and 2 feet long.. After its dry, cut a bunch of square blanks for the lathe process. Another hunt for the learning curve Go buy a fugly cutting board at a kitchen store made from these two woods, maple and mahogany Cut a few square blanks and turn up a few practise knows to get a feel for how fast you can cut, how to mount it etc etc. You will end up using a custom made deadman for the non driven side of the knob...not the pin it comes with. You turn that up out of rock maple or any super hard wood..rock maple is easier to find. It will be shaped like a cup, but very shallow to give you room to work. Use soap to keep it from burning.

As I don't have a plane or a bandsaw to make the thick boards thinner, where can I find mahogany and maple in 1/8 and 1/4 inch thicknesses?
Its easy in balsa or pine, but I was unable to find it in other woods. Zach |
