Norton titanium wheel spindles and 7075 alloy nuts
These are titanium wheel spindles for a racing Norton, the nuts and washers are 7075 alloy. The rear axle is a bit thin to bore lengthways, it would have taken a 5 or 6mm hole but the cost to weight advantage just wasn’t worth it in this case so i left it solid, still 40% lighter than original.
The front spindle was solid so i made the titanium one hollow which meant it weighed less than 50% of the original, and stronger too!
