Yesterday I tried to steam-bend a bow limb that was beginning to twist off-center. However, I got halfway through the process and realized I didn't have everything I needed. Since I already had a lot of boiling water I took a heatproof scoop and ladled boiling water directly on to the limb. I did this fairly slowly, letting the water run down the limb so that the limb remained coated in boiling water for the longest time I could manage. Then I tied the limb to a straight piece of wood and wrapped it tightly.
So, is this likely to work? Not work? Not work and destroy the bow?
