Arunda dovetail system

Arunda is a Swiss made system that allows carpertners to produce manually roof-frame and timber-frame assemblies using dovetail joints

 

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:

 

Arunda system Type-B
with fixed fences (stoppers)

Arunda system Type-N
with tilting fences (stoppers)

These "A" jigs with square fences and adjustable height are intended for making all right-angle joints, namely straight or angled joists on a stringer. Although not as convenient as with the tilting fence model, it is possible to create angled joints such as rafter-ends on the ridge beam using the "A" jigs. They are made out of solid steel and are particularly resistant. "S" jigs are fitted with sliding fences that can be tilted up to 50° in either direction. They can be used for all kinds of assemblies, whether perpendicular or angled. They are especially helpful in building roof systems which require milling dovetails on angle cuts, such as the joints on a chamfered ridge beam. The sliding fences can be adjusted to the exact roof pitch required.

There are 4 models of Arnda systems, each model works for its range of timbers

What about resistance of the assemblies?

 

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?

 

  • SPEED

    Arunda dovetail

      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 only with Mafell LO65Ec (2600W) router. This powerful Gemran made 3HP unit for professionals costs about US$1100-1300.
Woodlandia made special adapter for more economically priced Freud 3¼HP router (about US$300.00, made in Spain).

Theoretically one can make adapter for his own router of other brands but this can require extra time, efforts and expences.
