This is the M1-576 draw bar for the Atlas milling machines, this draw bar is required for the M1-577 shank-cutter adapter as well as the M1-560 and 560L arbors.
Due to the lack of avalibility of the materials outlined in the purple text below I am at least for now producing these arbors from stainless steel, I feel that this substitution is just as durable and will give at least an equal service life as my previous offerings and while the material cost is higher than I was paying for the steel the difference is offset since it is not blued . This also includes the coned centering sleeve.
The main body of this drawbar is manufactured in 2 pieces which allows me to provide it at a lower cost than if it is turned from a single piece of stock (which the original was) also provided is the coned centering sleeve which helps center the drawbar at the rear of the spindle. this drawbar is turned from pre hardened steel and is then finished in my hot bluing tanks so that it will have a long lasting protective finish which I feel is much more pleasing than a raw steel look.
I have shown on my u-tube video the manufacture of one of these arbors as per the print (which is redily available) and have provided the information necessary for you to build your own if you choose. and the photos here are of that arbor. That video can be found here
Thank you for considering the Atlas products I offer, your support allows me to continue to offer replacement parts and accessories at a more reasonable cost than is normally found on the auction sites, as well as to produce videos on how you can build your own replacement parts for these machines to help make them affordable again. Thank you, Dan.
