drive shaft cut
I have cut a lot using the farmer boy method. First find a drive shaft with no or very small factory balance weights. I lay the shaft on the steel table and use an angle iron next to it to scribe a straight alignment end to end . and spray some paint so you don't put it back together 180* out . I then chuck it in the lathe and make the first cut partially thru the rear, weld bead,, then measure the amount to be cut out and partially make that cut, then with the steady rest accurately adjusted, finish cut the end off, then finish the center cut, put it back to gether then as noted above tack weld, safety hoop.
