We are excited to introduce the Great Lakes Jack.The Great Lakes Jack was jointly designed by members of the Great Lakes Log Crafters Association, along with Aeshe Engineering. The Great Lakes Jack has a 1” threaded rod mounted to a 3/8” steel plate with a nut acting as the height adjuster, and another 3/8” steel plate welded on top of the nut. The bottom plate of the screw jack is anchored to the foundation through two 1/2" holes. The top plate is anchored to the bottom of the vertical log post with four 3/8" structural screws. The threaded rod passes through a hole in the center of the top plate as shown and into a pre-drilled recess in the log. Unlike other settling jack designs, the nut is welded to the top plate of the Great Lakes Jack. This aids in resisting uplift, but as such it's necessary to remove the anchor screws from the upper plate while vertical adjustments are made. Corrosion resistant coating should be applied before installation. Allowable net uplift is 900LBS, and Vertical downward force is tested to 20,000LBS.
A portion of proceeds from this jack go to the Great Lakes Log Crafters Association and help to fund their education and promotion of excellence in handcrafted log building. The Great Lakes Log Crafters Association meets annually for education, demonstration, and camaraderie of all things related to log craft. In 2025, the conference will be meeting April 25-26 at Gateway Lodge in Land O’ Lakes Wisconsin. Some of the many topics presented will be Net Zero Log Home: Purdue University Ross Reserve; Stihl Chainsaw and Milwaukee Tool Demonstrations; Wood Treating With Lake Country Log and Cedar; Wisconsin Building Codes; and Robotic Solutions, Inc- Software for log and timber manufacturing demonstration. Registration is open to all members and non-members who are interested in learning more about all aspects in the craft of log construction.
