He want's the .stp files which gives the CNC machine all the info it needs dimensionaly . The drawings need to be created in a program like Autocad or Creo and then saved as .stp . You need someone to create the drawings and files before you even think about quoting a job like that . For one offs like that I'd guess 75 to 100 dollars a wheel to make and thats just machining . That doesn't include someone to design them. They would be nice I admit .I've just had a reply from the gent at Flintshire precision engineering and here is what he said.....
Thanks for the enquiry
That is something we could do, as long as you have a CAD model of the wheel
Do you mean if I had all dimensions? If so I don't as there has not been anything done like this and I'm not too good at the design side.
I have include a few picture of the wheels in question and the sizes. The smaller ones are an exact replica of the RS wheels which I picked up when I was in Hong Kong and the white , larger wheel is the size I need.
Do you offer a design service or could you copy the smaller wheel in a larger scale?
We don’t design items like this, so without CAD there isn’t anything we could do to help
Well there we go , another dead end.
Yes and no. We have machine shops to make a lot of proto type parts. I've designed a lot of fixtures that we have printed in plastic printers I'm not that good at it compared to some (still learning) . I could probably do a drawing of that wheel in Creo but it would take me a week where other guys at work could whip that out in a hour or 2 . Hell I get to have fun every few months making stuff in our lab running our mill .
