Hey everybody my name is Brian, I am a total noob with this stuff but looking to learn. I just joined here yesterday, I am currently tearing down an Atlas MF mill. I have a copy of the parts list and drawings pdf from the vinatagemachinery site for reference as I go. For the most part it's going good aside from the oil/sawdust gunk covering most of the parts. A couple things though through me a curve, the spindle pulley is missing but has been replaced with drum along with the counter shaft pulley have also being replaced with a smaller drum. There was also this leather strap/belt around the counter shaft and back gear. Does anybody know what these parts are, and has anyone ever seen this conversion before? How would this effect the function of the mill? Attached are pics of the parts I mentioned. Thanks for any help I greatly appreciate it!
