I've never tried it for recurves, but before I got my heat gun I did try using an iron to make some general corrections to a stave. Even with it on the highest setting, and pumping out steam I struggled to get enough of the stave hot all at once. I was trying to get a lateral bend along most of a limb length though, and couldn't keep the whole length hot. With a tip flip you may have better luck because you're only heating 1 localized spot.
