I need some guidance on figuring out what the bolt hole co-ordinates
are to build a drive flange. The hub I need to bolt to has three
holes, evenly spaced with a center to center dimension of 3.607. How
do I calculate what the bolt hole x-y co-ordinates are to drill this
when held in the mill vice? thanks in advance, ron

AutoCAD check:
If the center of your bolt circle is the origin of coordinates, the
holes will be at:

X Y
1.804 0
-0.902 1.562
-0.902 -1.562
