I think a good place to train is in Al Kharid. I used to mine in Chasm Mine, smelt back in Al Kharid and then put my bars in the bank. Keep doing that till you have heaps of bars then go and smith in Varrock. :D
I need the presure gauge and I've read the guide and it says to use the poison fish food with the fountain outside the palace. What fountain? I can't see one anywhere. Anyone know? :-s
