Chapter 21 – Laminating Veneer Over a Mold or Plug 247<br />

(100mm to 200mm) wide, which span at least 25%<br />

of the half girth. For clamping pressure as the epoxy<br />

cures, use weights or cinch a line around the hull<br />

roughly the way you’d cinch a saddle <strong>on</strong> a horse. When<br />

the cradle seats have cured, b<strong>on</strong>d sufficient framework<br />

to them to permit the hull to sit close to its lines when<br />

turned upright.<br />

It’s fairly easy for a group of people to grasp a small,<br />

light hull by its sheer and lift it high enough to clear<br />

its mold. If your hull is too heavy or has to be lifted<br />

too high for people to handle, use a lifting sling and<br />

mechanical assistance. Usually, four pieces of extruded<br />

metal U-shaped channel large enough to fit over the<br />

edge of the hull at the sheer can be used as lifting<br />

points. Each of the pieces might be a foot or more l<strong>on</strong>g<br />

in order to distribute load over enough area to prevent<br />

damage to the sheer. You may want to screw the pieces<br />

to the sheer to prevent slipping. Attach a line to them<br />

and fasten it to the lifting apparatus.<br />

Lift the hull clear of its mold and set it <strong>on</strong> the floor.<br />

Cross brace the sheers in a few places close to the<br />

center of the hull so that they can bear the weight as<br />

the hull rolls. <str<strong>on</strong>g>The</str<strong>on</strong>g>n roll it over into an upright positi<strong>on</strong>.<br />

With enough people and padding, most molded hulls<br />

can be rolled by hand. See Chapter 23 for suggesti<strong>on</strong>s<br />

<strong>on</strong> rolling larger hulls.
