Harper ★★★★★ Oct 21, 2026

Finally, a setup block set that actually makes bird's mouth joinery repeatable instead of guesswork. The precision on the hexadeca block alone saved me from recutting a dozen waste pieces.

Miles Q. ★★★★★ Oct 20, 2026

Took a chance on these for my first bird's mouth project and the machined edges are dead-on, so the octa and hexadeca blocks gave me clean joints without fiddling. Setup took maybe five minutes total once I figured out which block matched which cut.

Andrew ★★★★★ Oct 19, 2026

The three blocks cover octa, hexa/dodeca, and hexadeca setups, so I can switch between them without remeasuring each time. First try on a test piece and the angles lined up perfectly with my router bit.
