@jareese If you do a "used metalworking machinery" search, you will probably find some hits. There are quite a few towards Milwaukee and Chicago. During my numerous treks to the Oshkosh Airshow, I drove by
this place which is in Waupaca. I have never been there, but
@pdentrem has been there, I believe.
I know that your anxiety is pretty high at the moment (mine would be through the roof), but before searches are conducted, and phone calls are made, we need to determine what is wrong with your lathe. 1.) I would take start by taking the saddle apart. The broken cross-slide casting is a great place to start. 2.) Once this is apart, any other damage can be assessed. 3.) Evaluate the headstock to ensure it is not cracked. A thorough review is required. 3.) Once this is all done and notes are taken, a call to Eisen is in order to determine their ability to provide replacement of parts that are broken/damaged. 3.) IF Eisen can't help you, then we will start down the other paths of A.) Used parts. B.) New parts that are provided by other mfgs. C.) Repair of your broken items.
But, until Eisen is ruled out (which I do believe that they will help you), I would not spend any time tracking down used machinery dealers or similar.
Keep in mind that there are other distributors of "this" lathe, so I believe the options for replacement parts will be more than just a few.
@Charles scozzari He lives in Wisconsin, so East Coast perusing of machinery dealers, other than by phone or email, is out of the question.
