Nail‑Tolerant Reclaimed Wood Mosaic

Built‑In Drywall Display Niche
Lay out a rectangle between studs and plunge‑cut the drywall cleanly for a pro‑looking niche. Vibration‑reduction slots help keep edges straight, and the 4 in segment spans long cuts quickly. Add a shelf and LED strip for a finished display.

Notch and window‑cut 4–6 inch PVC pipe to create staggered planting pockets for herbs or strawberries. The curved cutting edge and segment profile give smooth openings without grabbing, and the StarlockMax mount provides control for repeatable cuts.
Tile‑and‑Wood Inset Trivet
Make a wooden trivet with inset soft ceramic wall tiles. Use the blade for clean recesses in wood and light, careful passes to score or enlarge tile openings, then refine with a file. The circular weld and side‑set teeth help keep wood cuts clean.
Hex Shelf Cluster from Pallet Slats
Cut precise 30/60 degree miters and flush‑trim ends to build honeycomb shelves from nail‑riddled slats. The deep‑cut segment design keeps longer cuts steady, and bimetal teeth handle surprise fasteners without ruining the edge.
