These solid steel jigs are available in different models and sizes to suit builders' needs: the #50, #80, #120 and #160. The choice of a model is determined by the dimension of the timber most commonly used. The width of the beam is the only deciding factor to select the jig. Each jig model makes it possible to work on a range of timber widths. The bigger the jig, the wider the assembly and the greater the tolerance! It is therefore useful to choose the jig that best fits one's needs in order to ensure the greatest structural integrity of the building. A small beam requires a smaller joint, whereas a large beam calls for a bigger joint for maximum strength. Generally, only one jig model is necessary.
The jigs can be adjusted for various heights of tenon/mortise.
Arunda® System : The Advantages
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.
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).
You can produce perpendicular or angled joints on floor joists or rafters.
Usable on a wide range of timber widths: from 45 to 300 mm / 1¾" to 12" for the tenon. No limitation for beams to be mortised.
Identical router bit setting to cut both mortise and tenon, for all beams in the same series.
An authentically timber framed roof assembly.
Workloads are very high: up to 2100 kg / 4620 lbs per joint.
Jigs are just as easy to use in the workshop as on the job site.
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.
