I am steaming so yew today
, I just put a pot of water to boil with a rag for a lid, let her warm up and then bend it over a bowl unside down when I want it to go. There is fancier ways that would be perhaps better results, but for this bow its fine.
You should have your bow tillered a bit follow the grain, don't bother looking at where the string ends up yet, just get it looking like a bow, but carve the bow so the rings feathered out in the center of the bow, follow the grain and just pretend the bow is straight,
then when the bow is close to finished steam bend it to shape, you don't have to get it all in the 1st steam, it may take many attempts, let it cool for a long while between,
You can just hold it in place while its hot and bending for a few minutes and then leave it, more of it will stay if you tie it down and leave it, but with yew its kind of like playdo and you just bend it around, its fun !
then check if you string is lined up yet and repeat, you also might have to care the nocks a little funny to get the string to line up , you might have to carve the bow to make the limb twist, what ever.
In other words, the just before sanding I steam bend. It makes the carving out of the bow the most important thing. Its hard to carve it with the grain perfect.
Yew is pretty tough so don't worry to much about steaming it into shape.
