Quick Answer
Cordwood construction requires specific tools to ensure a successful project. Essential tools include a chainsaw, maul, axe, and trowel. A set of hand tools and a power drill also come in handy.
Essential Hand Tools
To start a cordwood project, you’ll need a chainsaw for cutting the logs into manageable pieces, about 16-20 inches long. A maul is used to split the logs, and an axe helps with finer cuts and shaping. A trowel is necessary for applying the mortar mix between the logs. You’ll also need a mixing bucket and a wheelbarrow for mortar preparation.
Power Tools and Mortar Mix
A power drill is helpful for drilling holes in the logs for rebar or wire reinforcement. As for the mortar mix, the ideal ratio is 1 part cement to 2 parts sand to 6 parts sawdust or perlite. This mix allows for good insulation and structural integrity. Make sure to use a consistent mix and apply it evenly between the logs.
Cordwood Wall Construction and Insulation
When constructing the cordwood walls, leave about 1 inch of space between each log for mortar and insulation. Fill the gaps with a combination of sawdust, perlite, and vermiculite, which provides good thermal insulation. A minimum of 8-10 inches of insulation is recommended for an R-value of 20, ensuring a warm and energy-efficient cabin.
