The Euro K Club Lounge / Engineering workshop wizard wanted...

I have a spurious need for some small, thin, unobtanium washers. Well, stainless steel actually but it seems that no one makes what I want, which is M6 Form C shims in about 0.3mm thickness. Oh and I need four of them.
The thickness is not too critical but the Form C bit is. That means that the outside diameter is greater than Form B for a given ID. Form B M6 (standard washers) have an outside diameter of 12mm whereas Form C has an OD of 14mm. And that is the critical bit.
The only thing commercially available seems to be M6 Form B in any thinness you like (I tried these but they don't work) or Form C in 'normal' thicknesses. I even tried US stockists for thin 1/4" x 9/16" which would do also.
So, do we have any clever clogs in here who can think of how to reduce common Form B 'thick' stainless washers down to sub-millimetre thickness or even have the wherewithal to do so...plenty of washers and beer provided to the successful wizard.
Of course, a lathe and some stainless stock would work too...
