You may be correct but I'm not asking someone to machine me one. I could do that just down the street but like you said, it would be expensive. I know for a fact that there is many of what I describe in existence and there may be someone that has no use for one and would like to take the opportunity to get something for it rather than store it the rest of their lives. I have seen them for sale before for a price I was willing to pay but I didn't need one then. I also think that when you are starting with 6hp, it is worth while to make an attempt to get one when you plan to use it on a generator head. If I was pumping water or something I wouldn't worry about it but a couple hundred watts when your total is only in the 3.5K range to start is significant depending on your plans for the power.

If you still have the pulley and can ship to the US, I'm interested.
