Arunda dovetail system
Woodlandia - Arunda project
Since 2008 Woodlandia is partnering with Arunda-Patrick Burli (Switzerland) to bring to North American log home builders and timber framers wonderful Arunda's dovetail tools.
Arunda is a Swiss made system that allows to produce manually roof-frame assemblies using dovetail joints. It has been granted an international patent and was designed for a simple and efficient use.
The Arunda system was developed in Switzerland too by wood building professionals and tool manufacturers.

What does Arunda consist of?
- Arunda system uses one pair of jigs (one for the tail and one for the pin), a heavy-duty router, a special dovetail bit and a few accessories.
- There are 4 models of Arunda jigs (there were 5 models till 2012)
- There are 2 types of Arunda systems produced:
There are 4 models of Arnda systems, each model works for its range of timbers(till 2012 there were 5 models of jigs available) |

What about resistance of the assemblies?
- Please review this datasheet (click here) with "Table of working loads - Dimensioning of dovetail assembly".
- Here is another datasheet with "Table of springer/purlin weakening - compensation to offset the pin cutouts" ( please click here to download)
This data can be used by you or your engineer to calculate working loads of your timber-frame or roof-assembly.

What are Arunda's benefits?
Fast implementation of the timber frame assemblies : 8 to 18 mortise/tenon joints per hour.
- EASE OF USE
The vertical mortise and tenon dovetail assembly is very fast and easy. No need to spread the beams to insert tenons, as with straight tenons.
- PRECISION
The conical shape of the dovetail joint is self-tightening: The male and female parts fit perfectly and hold together. The tightening strength of the assembly can be modified and adapted to the nature of the wood (dry gluelam or solid wood).
- FLEXIBILITY
You can produce perpendicular or angled joints.
- VERSATILITY
Usable on a wide range of timber widths. No limitation for beams to be mortised.
- TIME-SAVING
Identical router bit setting to cut both mortise and tenon, for all beams in the same series.
- QUALITY
An authentically timber framed roof assembly.
- STRENGTH
Workloads are very high: up to 3745 lbs (1700 kg) per joint.
- MOBILITY
Jigs are just as easy to use in the workshop as on the job site.
- ECONOMY
A low-cost replacement for metal connectors, which are expensive and take longer to implement. With Arunda, you make a one long term investment. The system is available anytime to produce joints of several sizes.

Can I use my own router with Arunda system?
By default Arunda is intended to work with either:
- Mafell LO65Ec (2600W) router. This powerful Gemran made 3HP unit for professionals costs about US$1100-1300.
- FESTOOL OF-2200 EB
- SCHEER HM25 (HM18)
Extra option from Woodlandia only
Woodlandia makes special adapter for more economically priced Freud 3¼HP router (about US$300.00, made in Spain).
Theoretically one can make an adapter for his own router of other brands but this can require extra time, efforts and expences.
