A couple days ago I was reading a post on here about chuck adapters for the tail stock. I had just finished getting my vacuum chuck system online and realized the benefits of such an adapter. Here is my version. I purchased a 1"8tpi grade 5 bolt and nut (about $10). I turned the head off the bolt and installed the nut (locking type) and trued up the face of the nut. The end that was the head was turned to about 5/8" and fits nicely into my MT2 drill chuck. Now I have every thing I need to reverse chuck a turning without having to resort to my doughnut chuck or a jam chuck. The last photo is not really part of this but I thought I would throw it in here. It shows how I use my dead center chucked up in my Nova chuck for between center turnings. My BCTs are usually to put chuck tenons on vessel blanks so this works out real well.
