Warm water is good, but not too warm, just over room temp. If it's too warm you'll "cook" the cologen in the hide and it will lose its elastisity. While the hide soaks I apply a thin coat of Tite-bond 2 to the 1st limb to get hide with my finger, wait till it starts to set and gets tacky, then apply another thin even layer of glue, lay the hide down rough side down and smooth out the air bubbles. Wrap with ace bandage, Do the other limb, then counter wrap the limbs with rough nylon cord. Let dry a few days then remove cord, dry overnite and remove bandage. Do NOT bend bow. If the hide seems secure give it another day then remove any hide that overhangs the sides of the limb. Still do not bend bow. I'd give it at least a week or to to cure before further tillering depending on humidity in your area.
