The Leshy
Interlocking log-cabin-style planks from pallet wood and homemade glue, no router or milling equipment required — the joint is entirely hidden once assembled.
Why the name
Named for the Leshy, a shapeshifting forest-guardian spirit from Slavic folklore who watches over trees and can show (or hide) the true path through the woods. Fitting for a technique that turns scrap and pallet lumber — wood already pulled from the waste stream — into a joint that hides itself completely once two planks are slotted together.
Stack three flat planks together — pallet wood or cheap/scrap dimensional lumber all work. Offset the middle plank relative to the two outer planks: the offset on one side creates a tongue, the offset on the other side creates a matching groove. No router or precision milling required — the offset stack does the shaping.
Assembly
- Stack the three planks in the offset configuration described above.
- Glue the stack together — homemade hide glue (rendered from rawhide scraps) works, no purchased adhesive required.
- Clamp until set.
- Run a bead of glue along the seam for reinforcement.
- Brad nail through the seam for extra hold — optional, not structurally required if the glue bond is solid.
The finished plank has an integrated tongue on one edge and a groove on the opposite edge, letting planks slot together log-cabin style without a router or precision milling equipment.
Advantages
- No router or specialty tooling required.
- Works with scavenged pallet wood or cheap dimensional lumber.
- Adhesive can be homemade hide glue from rawhide scraps — zero cash material cost.
- Nails optional, not structurally required with a solid glue bond.
- Self-jigging offset ensures consistent tongue/groove alignment.
Open Items
- Exact offset/thickness dimensions still worth documenting from Zach's own test pieces before this goes into a formal build spec.
- Full wall-system application (stacking these planks into an actual log-cabin-style wall) is a natural next step, not yet built out as its own card.
