I understand your concern about the hot water method, Ossage, but I've come to prefer it in the past year.

I used to heat twisted limbs over a hot plate, then went to using a hair dryer on high heat and then to a heat gun to fix them. Problem with those is, if you get careless you can heat the limb unevenly or too much, break down the glue and delaminate the limb.

If the bow's finish is in good shape, the hot water method is better. There's no way you're going to get the limb too hot with hot tap water and the water heats the limb much more evenly. Even if the finish is screwed up, putting a healthy wax job on the limb before heating it will keep the water out.
