So these first two photos show the magnets turned out (no pun intended) after I machined them in the lathe.  DO NOT even thing about doing this, I was almost in tears when coils of copper started unwinding from the middle as the cardboard sandwiching it all together slipped apart    but the end result was worth it  

the last pic show the reinforced target I machined up from a piece of 10mm x 10mm stainles steel square section tube.

Unbelieveable feeling playing that first game, could not wipe the smile off my face, all that hard work paid off
