South Bend spindle adaptation

[blockmanjohn]

Hi, I have a Vertex 8" rotary table with a MT3 center hole. I also have a South Bend 9 inch lathe. I would like to use my 3 and 4 jaw chucks, which have 1 1/2 8 backplates, on the table. I also have a very used South Bend 9" spindle. Do you think it is possible to cut and turn a mt3 taper on the spindle so that I can insert it into the table and screw my chucks onto it ? The spindle is not hardened and has no value as a replacement part. Thanks, John
