I decided to draw up some dimensions of the original draw bar for my 8520 and the one that cam with the spare head I had purchased.
Though both will work with my mill, there are some differences as you will see in the pics.
General measurements were done with tape measure and digital caliper, thread pitch was measured with thread gage.
Draw bar that came with my mill:
Spare head draw bar:
I also did measurments of the draw bar collar:
Curious to know why the difference if there is any.
