Sine Bar Protractor
« on: February 14, 2018, 02:54:39 AM »
I made this sine bar protractor a few weeks



To use all you have to do is zero your height gauge on it



Then as the distance between centres is 100mm simply multiply the sine of the desired angle by 100 to give you the height to set the bar to using the height gauge.



Then use it to set up your work piece
