Check the video above to see it in action.

I decided to make my own wood cutting jigsaw, i did it for fun, has always i learn a little bit more in every new project.

I cuted and trimed an old dvd drive interior metal support to be the blade suport, did the same for the wood parts, cut and trim.

I wanted to have a stedy blade, because of that i created this mechanism to allow full movement up and down and no movements for the sides

After the final measurements cut and lock the metal rod that will conect to the second pulley from the motor with a rubber band

I decided to change the pulley system, i replaced the two pulleys to have a smoother transmission

Closing the motor compartment, assemble the module case and putting the handle together

Painted black for the handle and apply wood vernice and clear coat, connect the switch that will control the motor

Connect the module and the switch, close all the compartments

Assemble the blade using two screws with nut and is ready to test

The cut is very straight, good for small pieces.
