An electric jigsaw, due to the small width of the saw, is considered convenient when cutting along curved paths and unsuitable for the same reason for straight cuts. If you do not use the guides, then it begins to be taken to the side. But by equipping the tool with an elementary device, the above disadvantage can be avoided. For its manufacture, only the simplest materials and some skills of plumbing and carpentry are needed.
It will take
- electric jigsaw;
- one laminate board;
- high performance adhesive sealant and superglue;
- a metal sheet;
- round small neodymium magnets – http://ali.pub/4yy1yd
Instruments: marking square, ruler and marker, hand saw, electric drill, clamps, emery machine.
The process of making a fixture to ensure a completely straight cut
We install the sole of the jigsaw transversely along the edge of the laminate board, leaving a narrow strip outside. At the same distance from the other edge of the sole, we draw a transverse line and cut off the marked fragment of the board, while removing the lock.
Using the resulting fragment of the laminate, cut off another one of the same width.
We put the sole unscrewed from the body of the jigsaw on one of the fragments of the laminate, circle it around the perimeter with a marker and cut it out.
We put the resulting frame on the second fragment, and place the sole of the jigsaw in the recess. We mark the longitudinal line of symmetry of the sole on the solid fragment and the position of the central protrusion. At the mark of the central protrusion, we drill a through hole and from it deep into the solid fragment we make a slot.
We glue the frame to the second fragment with highly effective glue and, fixing it with clamps around the perimeter, leave the structure until the glue hardens. Grind the perimeter of the double fragments on an emery machine.
We insert the sole, screwed to the jigsaw, into the recess and mark from below the location of the back side of the file. We measure the distance from the blind end of the cut to the location of the saw and its overhang.
Cut out a quadrant from a metal sheet, the radii of which correspond to the distance from the blind end of the cut to the location of the saw, reduced by 1-1.5 mm.
In the bottom of the cutout for the sole of the jigsaw along the side with a large hole, mark and drill four small blind holes and two more on the other side. We fix neodymium magnets in them with the help of high-performance glue.
Insert the quadrant with one radius into the cut of the base from the laminate from below and fix it with superglue.
We insert the “native” sole into the recess of the sole made of laminate.
At the same time, when cutting the material with a saw, the metal quadrant located behind it in the cut ensures the straightness of the cut, preventing the tool from moving to the side.
And this can be clearly seen during test cuts.
