Very nice. In my workshop, getting to the rear fixing is awkward. I've considered making something similar for the front fixing, but with a double hinged rear fixing.
If the mounting had two hinges which were parallel but spaced apart by, say, two inches (50mm) then you wouldn't need to get to it to adjust it. If you were cutting thin stock, the spacer would be nearly horizontal, and if you were cutting 8/4 stock it would be vertical.
I hope my explanation is clear enough!
