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 |

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.
