If you are going to try to tame a rock golem I highly advise you to bring a couple cannons because if the golem can hit the cannon it will and it will destroy it with just 3 or so hits so bring 3 cannons and a bunch of cannon balls! I learned the hard way. Don’t make my mistake!
There is a great little natural passage that you can kite the golem in to at 64.1 - 49.9. We tame all our Golem there. They can't get out but once tamed can be moved out. It offers a great firing position for your cannon.
