The wood block is just for leverage....cant remember what the post name was but I have pics in it where I took a couple inches (lateral) out of some osage and even showed the stove clock to prove the timing.
You put the bend in after 5 min of steam, do the bend, and hold it in place for maybe 2 minuets.....done .....but if you feel the wood it will still be hot as all get out.

PS if it will help, I'll redo the pics of a actual bend with the clock in the pics and how I do it.....I think I can sweet talk Mrs. into a few minuets of her time. One other thing....even if I steam in the evening, the bow is ready to work the next day with no issues. Did ya ever notice when you take the wood out after an hour how the wood looks bone dry? If ya bend it like I do the wood will be "wet" when bent and only needs to dry some.
