Firstly, this is for a bicycle project, not a car, so not a high-stress component.
What I want is some alloy discs (probably 5 total,), 4-5mm thick, around 130mm outside diameter, with accurately machined inside diameter. I simply don't have the tools to do it myself.
If anyone here is interested, please respond. I will of course pay in advance for any work done. I know that skilled time is valuable, so I am happy to pay your going rate.
If you are interested, please let me know.
