This is just a short insructable on how to make straighter lines with a circular saw for less than five dollars. Making straight lines is great when your making anything worth anything. And as you know by hand is usually not straight.
Step 1: Assembly
the material that I used was a one by one, 36 inch length piece of angled aluminum. This ran me about 4.50 in home-depot. I used the circular saw to cut it into 12 and 24 inch sections then using a square or other known right angle drilled and riveted the two pieces together.
Step 2: Features
This aluminum square allows you to make straight lines up to 2 feet out with a circular saw using the first angle to clamp to the material and the second to guide the saw. If you liked this inscrutable please check out my channel GarageBot I promise I do more than pop rivet two pieces of aluminum.
