Centre Square

thingiverse

This item is taken from a Centre Square which I had to produce as part of my engineering apprenticeship. I still use it today...... To use it, you simply place the Vee shaped portion onto the end of a square or round bar of material and scribe a line across the middle, then move it around the end by 90 degrees and scribe another line across. Where the 2 lines intersect will be the centre of the material
