Chakster, Until now, I did not know where the OP is located. Obviously, his capacity to interact with a machinist in Oregon is limited by geography. However, if a competent machinist knows the parameters (possibly M30X1.0), then the OP may be able to locate one to make this piece for him. OR, as "imhififan" has shown, he may be able to buy the part on line with no fuss. Or, has he contacted you to take advantage of your own kind offer? Cripes, I am in the US, and I buy car parts from the UK all the time; shipping is not THAT crazy, and the parts start out being cheaper and much more available in the UK than here.
As to your own problem with the set screw in the B60, I suggest McMaster and Carr, which is also in the US, but the part is so tiny that shipping probably could be reasonable. Another source is "Mr Metric", on-line. And, Colby Lamb offered to machine for me a special set screw for my B60 similar to the improved version that Nandric had made in Europe. (I think that's correct; with a squared off protrusion at the end to engage the channel in the B60 and thereby eliminate side to side motion.) However, I have delayed that little project because I am so pleased with the FR64S/B60, as is; I don't want to take it apart and be deprived of its use. Or, you're closer to Nandric than you are to Colby Lamb. Funnily, I have bought audio capacitors from Russia and the Ukraine. Shipping to me from those locations is faster than from Canada. (Both the US and Canadian Customs Officials are fanatical; it seems they are not happy unless the border transit takes at least a week.)
