There is a better way to make the bracket:

   /---\ x  b
  |  C  ---/  C
  |     ---
   \---/ x

The x is where the bolt goes and C where the core goes. Covered with 
thick heat shrink tube to avoid damaging the wire. At 'b' it must curl 
back to avoid making a hole in the wire with the sharp edge. This part 
can be made to retain a nut (preventing it from spinning).
