Bottom Bracket Component
Hi, I'm looking for someone with the capability to machine an alloy piece for a bicycle bottom bracket. 100mm x 46.025mm hollow cylinder, threaded both ends with a BSA/English thread (one side with left-hand thread). I am hoping to press it into a 46mm bottom bracket shell. I've suggested an overall diameter of 46.025 to ensure it is a good fit, but open to advice if that is likely to be too big to press in.
I have suggested a 6061 Aluminium, same as the existing bottom bracket shell.
