The excess is measured and returned to the treatment drum. One test post from each batch should be assessed for creosote penetration. Split the cut sections to examine the penetration. If the sapwood is not completely impregnated, especially around the ground-line position, longer treatment is needed. Draining troughs made by cutting a 205 L drum lengthwise, with leaning rails to support the posts standing in them.
Electric base hotplate with thermostat, and thermometer to monitor temperature.
Insulation to wrap around the hot drum, to improve heating efficiency. Metal grid to fit the base of the drum, to raise the posts off the bottom and allow the creosote to readily penetrate the ends. Dipstick to measure changes in preservative levels. Wear full length clothing, gloves, goggles, shoes and hat while using the product.
