legal throwing implement

[rocky]

we have a worn out wooden discus (the wood particles continue to fall out.) My thrower/shop student wants to use new wood to "fix" the old thing. two questions, 1. when he is finished( and he is about done-looks nice) what is the official weight for high school guys discus? 2. is it legal to throw in meet providing the weight is correct.

thanks to those that help me out.
