Angle Measuring Tool

Here is a single print that measures inside and outside angles to within +/- 1 degree.

It is one print with no support needed.

The pointer hole provided me a medium press fit on the pin.  This allowed the pointer to turn,, stay in place, and not fall off.

If you find the pointer hole too tight or too loose, a second file with smaller and larger holes in the pointers is provided.  Use a knife or sand paper to remove any elephant foot on the edges of the hole.  A tight press fit requires the pointer to be “screwed on” to the pin by pushing down and rotating the pin.

The large hash marks are 10 degrees apart and the small hash marks are 2 degrees apart.

The outer edges provide 30, 45, and 60 degree angles.  I use the 30 and 45 to confirm my table saw angle is accurate.  The scale on the table saw hash marks are a bit wide, which has made the angle set a bit inaccurate.  One picture show a slight gap between the table and the saw although the table saw index indicated a proper setting.

If you have trouble with the press fit, drop a note and I will try to adjust the design.
