One method of setting the scroll saw blade to 90 degrees is to use a protractor. These things can be expensive. I have seen the plastic ones go for as much as 75 cents. I'm about to save you the burden of spending all that hard earned cash. You can thank me later.All kidding aside I had a reason to make this gauge. I'm getting older and my eyes are not as good as they once were. I was having a difficult time seeing the green plastic protractor I have. I wanted a white background so the visibility would be better. I was not sure I could get it accurate enough but it was not as difficult as I expected.
This pattern book has the full instructions for making an accurate DIY angle gauge. Believe it or not you can get it very accurate with just a little care. The accuracy of your printer is important. The pattern is best printed on a laser printer but most high quality ink jet printers should work.
