Hi Roger - thanks for the input.
Looking again at the drawings, perhaps we don't need such a tight callout on the OD, just a limit dimension on the OD that it's no smaller than x.xxx and allow a larger variation above that of +.005" or possibly even +.010"?
I guess I'm asking what is a reasonable tolerance to get a fairly reasonable price, if you don't mind advising?

The original parts are turned, but these are a modification at a different size, so we can't get them from the OEM.

Thanks,
Steve

Should not be a problem to machine as they are in your first request, they already have a large tolerance I would of given you a quote but will not be available for a few weeks

You could use Delrin as well which would be better for wear than the nylon
