It's worth checking that the crown race and fork have the correct dimensions to achieve an interference fit as required.
From experience, if the fork is oversized and needs facing, you can use the @PhilDAS method but all you'll achieve is an experience of frustration, tinnitus (I recommend putting some earplugs in) and eventually taking it to a shop where they'll face the fork for you.
At the Artisinal framebuilding workshop I worked at for the last couple of years, we put the crown race setting tool over the steerer, turned the whole fork upside down and whacked it against a concrete floor. Never failed. The Earth is a pretty big hammer it turns out.
