Jigs female/male for timber frame dovetail assemblies

Purpose of the system

Arunda is a system for manually making dovetailed wood-to-wood joints to assemble timber frame structures. All you need is a pair of Arunda jigs (one for the tenon and the other for the mortise), a powerful router fitted with the special Arunda bit, and some accessories.

Process

Using a simple rule, you determine the height of the assembly (for instance: 150 mm / 6").
You set the jig fences to the figure corresponding to that height.
With the lever clamps, you fix the male jig on the end of the timber to be tenoned and the female jig on the beam to be mortised.
Using the router coupled with the special Arunda bit, you mill the male and female dovetails. Remove the jigs and your joint is ready to assemble!

Types of assemblies

You can make the following common assemblies :


Joist to stringer	Offset joist to stringer	Skewed joist to stringer	Short joist to stringer


Two beams joined at 45°	Two beams connected to corner post	Rafter to square ridge purlin	Rafter to chamfered ridge purlin


Rafter to base plate (wall beam)	Rafter-to-rafter (without ridge purlin)	Stringer to through post	End-to-end connection

Working loads

Working loads per assembly go from 5.12 kN (512 kg = 1130 lbs) to 21 kN (2100 kg = 4620 lbs). Jigs are delivered together with an instructions manual containing a detailed table of working loads.
