If this works I'm going to do some skip tooth chains. They're rather expensive to buy new and there's not that much wear on them.

As far as newer chains, I don't bother trying to get the old one lubed up. If it's going on a cheaper flipper I splice pieces of good chain together and call it good. If it's a nice flipper I put a walmart chain on it. If it's a keeper I get a nice SRAM. (You can see where my priorities are) There are no refurbished chains in my shop.

EDIT: To add to the horror of what I said about splicing, I also splice cable housing pieces together.
