i made some metal nunchucks during my work placement in metalwork where i had to go to a real working place for a week, i lathed 2 metal hollow handles, then put another rod inside which would rotate when spun because the rod was welded to the chains i used (chains suck for nunchucks but i had mikeys ones in mind)
speaking of UK, is the new series over there called 'teenage mutant ninja turtles' or is THAT still too violent sounding
