machined

With this quarantine, work has been slow. Decided to machine up some rear axle nuts for the 899/959. Prototyped out of 6061, held the torque just fine. Machined a few for myself and some friends out of 7075 for the additional strength. Threads are threadmilled for a higher quality and stronger...

My Triumph has warped rotors causing a pulse through the front end. One is out by 5/1000ths, the other is out by 10/1000ths. I know it doesn't sound like much, but it feels horribly off. :( Can warped rotors be machined true? If so, can anyone recommend service providers?
