Cordwood Tips, Tricks and Hacks to help you build better cordwood.
- Keeping your wall level? Try using a swinging plumb bob.
Usually, a plumb bob is hung on a string to show vertical plumb. This idea is courtesy of Don Gerdes (engineer) who devised it to help keep the walls in his cordwood home straight. The trick is to take a straight 2 x 4 and drill a hole in the top. Drill a deck screw into the top plate and hang the swinging plumb bob on the screw. Every row, swing the plumb bob & lightly tap the logs in or out. Saves time and gives you a quick way to keep it all in proper order. [“Plumb” is what you call a perfectly vertical line. Vertical means up and down. Something that is “plumb” runs perpendicular to the horizon—meaning that when it intersects the horizon, it makes a right (90 degree) angle. You can measure if something is plumb by using a plumb bob or a spirit or laser level.” mtcopeland]
2. Mason Lines let you level your cordwood by looking “down the line.”
Cliff Shockey (double-wall inventor) demonstrating how to build the inside portion of a double wall. Note the masons lime for keeping the horizontal level, the vapor barrier, the grey insulation and the outside double wall. Cliff will move the mason’s line up the wall as he makes progress (notice he has already set the roofing nails in 12″ increments).
As you build the wall, you can site “down” or along the masons line.
3. Exploding Logs
Split larger logs into pieces and then put them back together in the wall. This will eliminate a primary check and reduce shrinkage.
4. Tuck-point with a paintbrush.
An excellent way to finish off a cordwood wall and smooth out all the mortar is to use a 2″ paintbrush.
5. Peel wood like a Boss.
This peeling spud with a long handle allows you to put your legs and back into the peeling process.
6. M-I-M Sticks
Mortar-Insulation-Mortar Keeps your mortar beads even. If you have a 16″ wall and you have a post framework, the measurements are 3 inches of mortar (outside and inside) 10 inches in the center cavity. R-value for a 16″ wall is R-24 as tested by the University of Manitoba Engineering Department.
7. Splicing and notching posts and beams.
Two LVL’s spliced in the middle of a post for secure anchoring. Notice how the post is notched to “take” the weight of the LVL’s and whatever might sit upon them.

“Richard & Becky Flatau built their mortgage-free cordwood home in 1979 in Merrill, Wisconsin. Since then, they have written books, conducted workshops, facilitated the 2005, 2011 and 2015 Cordwood Conferences and provided consultation for cordwood builders. Cordwood Construction: Best Practices DVD, Cordwood Construction Best Practices (print) and Cordwood Conference Papers 2015 are the newest publications available from their online cordwood bookstore.” www.cordwoodconstruction.org
