I really wanted to try a bow with bent limbs, but I'm poor as all heck so I couldn't make a hot box.
So, I think to myself, "Well, if I want heat and steam, I can get that from the stove, right?"
I then set a pot with water on my electric stove and laid one limb of the bow over the water with just enough heat for a boil. I also covered the limb and stove with a tent of aluminum foil. Thirty minutes later, it worked!
When I set the other limb up, it actually cracked across the belly about 20 minutes in. (I'm going to see if I can tightbond the belly, because the crack doesn't reach the back. Probably wont work :p )
However, I did learn it can be done!
(edit: Scratch that repair. It totally just snapped in half)
