I think that's BRILLIANT! One thing. Are sure about the 1.0 thread pitch? M8-1.25 is the normal pitch for 8mm. 1.0 would be considered fine thread. I'm not saying you're wrong, I'm simply asking. Just like Frankenstein's head, you're the one with the bolt. I'm only looking at your picture and being honest. It doesn't look like fine thread to me. But I've been wrong very many lots of times!

In case I find myself at an Ace (not too difficult as it's inside the Piggly Wiggly, even using the PW cashiers!) do you know what the bolt's length is?
