Well if you have any luck finding anything let me know cause I know someone who has one as well. I have tried and havent had to much luck finding stuff.
Have you or they gone out to the Mini Max web site and sent an email to the customer service department about getting an electronic copy of the manual?
The lathe they currently carry is not prominently displayed on their web site but the do have a T124 so I would presume the customer service group would have information on earlier lathes.
