Preparation and cutting
6.1
Safety
CAUTION:
Wearing safety glasses and hearing protection is mandatory!
6.2
Trial cutting and check before series production
Always carry out a complete trial cutting before starting series production!
(identical with the timber that is going to be used for the series)
Three important points can thus be checked:
-
the pin height
-
the pin socket depth - similar to the pin height
-
an adequate clamping force of the joint (pin in pin socket)
6.3
Setting the stops at the jigs
6.3.1
Height-adjustable stop
Move the depth stop of the male and female jig to the desired position of the scale division in mm or inches and
tighten the screws firmly.
6.3.2
Sliding stop
The lower stop of the male jig 9 must remain freely movable so that it can adapt to the beam when the lever
clamp is tightened (Fig. 7).
6.4
Positioning the male jig
6.4.1
Male jig fixed with lever clamp
Place the male jig 9 vertically on the end of the beam at which the pin is to be cut (joist) and position it
correctly. Centre the step-shaped stop on the width of the timber or the centre line. Move the lower sliding stop
upwards. Clamp the timber between the two stops with a lever clamp 10 (Fig. 7).
6.4.2
Male jig fixed with screw
In the case of obliquely cut beams (e.g. rafters), it is possible to fasten the template 9 using two screws (see
arrows in Fig. 8).
6.5
Positioning of the female jig
The centre of the pin sockets is marked in the upper part of the main girder. The female jig 11 is centred on the
centre line and fastened with two lever clamps (Fig. 9), or in the case of obliquely cut joints with two screws.
6.6
Cutting the pin
Prepare specimens with which you produce a complete joint before starting series
production.
Observe the direction of travel of the cutter and cut in the direction of travel of
the cutter (Fig. 10).
