OT, I've just soaked thin strips (1/8" cherry) in room temp water overnight and had good bends. thicker 1/4" jatoba in hot tap water could bend nicely for a arch strip like I used in my Harvey Ellis mirror, but I'm sure the hotter the better for the sharper bends (obviously from Rick's marble ramps!)

Steam is of course the ultimate and plenty of info on doing that, but wood species/grain plays a big part in success
