I need to cut a 3 inch radius in the face of a panel of plastic. Let's just say it is nylon (it is not but close enough). I am making "dog-bone" tensile testing specimens from this slab of material. I intend to cut the side profiles in the slab (one side first and then flip it over with support) and then part off the thin individual specimens using a wheel.
The 1" thick panel is 7" by 12" and I need to make the radius cuts such that the axis of rotation is parallel to the milling machine table Y axis. I do not have a 6" diameter cutter, nor do I have a CNC mill. So, what I am asking is if anyone has experience using a large fly-cutter "sideways". I intend to do the work in a Bridgeport using a right-angle adapter on the quill and a large fly cutter operating such that the circle is facing the operator of the mill. I will use the Y axis of the mill to cut the radii.
