Intro: Homemade 12V JIGSAW Variable Speed
Step 1: The Beginning
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.
Step 2: The "mechanism"
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
Step 3: The "pullys"
After the final measurements cut and lock the metal rod that will conect to the second pulley from the motor with a rubber band
Step 4: First Test
I decided to change the pulley system, i replaced the two pulleys to have a smoother transmission
Step 5: The Handle
Closing the motor compartment, assemble the module case and putting the handle together
Step 6: Painting and Switch
Painted black for the handle and apply wood vernice and clear coat, connect the switch that will control the motor
Step 7: Almost Done
Connect the module and the switch, close all the compartments
Step 8: Blade Mount
Assemble the blade using two screws with nut and is ready to test
Step 9: It Works !
The cut is very straight, good for small pieces.
