You need two size hammers,one small one to smash your piggy bank.And then one extremely large one probably to smash your house !!.My advice is buy a mig and learn how to use it.Loads of time but a lot less expense and you know whats been done and whats not.It never fails to get hands on,good luck.
Btw this is far from a pisstake,this is my advice

thanks for that i thought abt it an the more i think it seems like the right way to go abt it thanks
