Went to estate sale. Started this thread on antiques forum and was advised to go to this forum: I was seduced by a hunk of iron and a motor attached to a table and $100 was causing smoke in my back pocket so I opened it's cage and it followed my home! A few questions: Is there a neutral position that is somewhat elusive to me so that hand knob on the lead screw is free to turn? I can't find the model plate on mine; is it hidden somewhere? Are accessories such as chucks interchangeable from one model to another? Thanks for any help?
