I generally like to have mine thinner than most, 3/8 to 1/2 inch. You didn't mention heat source for bending.
I boil mine about 45 minutes, bend , set bend with heat gun as soon as they cool. Give it a day to a week depending on mood and start tillering. I also like to pay attention to belly growth rings around bend area, it seems that I have better luck if I keep the bend within a growth ring. If a ring runs out in area I'm bending I am more likely to raise splinters or belly cracks there. Good luck!
