Your're welcome, and if you know anyone in the UK that knows how to heat treat the alloy rods I have had forged - a European first according to the material supplier, then please let me know, as two major facilities in the UK are not sure they can. As for the last paragraph, the steel I am interested in, some on here will have handled it, fitted it or even flown in military aircraft using it. It is hugely more expensive than S132. It has been used to replace gears and can be made two 3/4 the size of the gear it replaces and still handle the same power - it is now on sale to the public. Deep pockets though. As for the rest, read the research papers that are a little more hidden on the web, most are independent and come from research facilities and Universities in the US, UK and the far east, most confirm what we as owners know, some are surprising, especially the those that deal with modern oil and surface finishes, machined, polished and coated, no wonder more oils are becoming so engine specific.
