How to prevent Ironbark from splitting and twisting when curing?

Splits and cracks (also know as checks) are common occurrences as wood dries. The shrinkage within the wood happens disproportionally as it dries, causing some parts to unevenly change in size, subsequently causing the cracks. To avoid cracks, the key is to remove the moisture from the wood slowly. These checks are hard to avoid without using a vacuum kiln or placing the timber away from direct sunlight. All Coach House Timber products are kiln dried beforehand, allowing a superior finish.
