The Mafell Arunda 80N Midi Dovetail Joint Milling Template System delivers precision wood-to-wood joinery for timber frame construction and post-and-beam structures. Designed for mid-sized structural timbers ranging from 80 mm to 140 mm (3-1/8 in. to 5-1/2 in.) in width and 90 mm to 300 mm (3-1/2 in. to 11-13/16 in.) in height, this template set produces clean, high-load dovetail connections without visible metal hardware.

Used in conjunction with a compatible high-performance router like the Mafell LO 65 Ec, the Arunda system streamlines shop pre-fabrication and jobsite assembly. The matched pair of tenon and mortise templates enables fast, accurate cutting of interlocking joints that drop together easily from above. The inherent geometry of the dovetail joint provides a tight fit that strengthens as load is applied, preserving structural integrity while improving visual aesthetics.

The Midi configuration includes the primary components needed for immediate operation: both tenon and mortise templates, dedicated cutter head with reversible blades, guide ring, setting gauge, extra blades, and a protective wooden case for storage and transport.

Features & Benefits

• Mid-Range Structural Capability: Specifically proportioned for 80 mm to 140 mm timber widths commonly used in ceiling joists and post-to-beam framing.
• Hardware-Free Timber Joinery: Creates flush, interlocking wood connections that remove the need for metal brackets or timber screws.
• Matched Template Alignment: Identical stop geometry on both tenon and mortise templates guarantees repeatable fit and eliminates layout errors.
• Angled Joint Support: Allows cutting perpendicular or angled connections from 0 to 50 degrees for compound timber designs.
• Precision Milling Setup: Guide ring and positioning gauge maintain consistent tool depth and offset for reliable joint tight-tolerance fit.
• Wooden Storage Case: Keeps precision aluminum templates and router tooling protected against jobsite damage.
