CUTTING ALU:

I've modified the jigsaw because the pieces didn't fit because of the prolonged use. I've cut and removed everything unnecesary, the table is made from two alu sheets and wood between them and feet are from kitchen furniture, under them you got the jigsaw inverted. The most important, the other side of the saw is joined to a steel bar, which elasticity keeps the saw tight during the use of the tool.

There's no schemes from the invention because it depends on the jigsaw you use. The materials are all from other broken tools and furniture. The jigsaw is a Black&Decker whit a screw fasten system, removed the original and put a homemade one to fasten the saw.
