Ok, these are now unicorn poop, where would I go to have one CNC made?
Local bike guys with a CNC machine ball parked $500. I’m thinking UK mail order likely a better option as there must be some healthy competition in the UK.
Have you been through the usual suspects? North Shore Billet, Wheels Mfg. , BETD?
The machining is cheep, but its the one off fees to CAD it that will make up ~£400 of that £500, then someone has to load the machine etc rather than making a hundred at a time from a billet. Getting that as one off is never going to be cheap.
Gone are the days of popping into to see Fred in the toolshop and ask if he can knock you up one in his lunch time. Get the shape drawn up in an autocad compatible file, get the shape laser cut and someone to drill/tap the holes – it certainly doesn’t need 500 quids worth of CNC machining.
