milling with chester 262 milling machine.

centering chuck to rotary table for drilling back plates for ER40 which i am making. since i got this mill really i did not use. for lack of tooling. what i discovred that R8 ARBOURS / ARBORS are different in regard to the slot depths and widths on these arbours. some of them deep and wide and the others are not, hence they do not go through the spindle because of the guided pin inside.
