I make a handheld drill chuck holder for lathe tailstock

I have a few drill chucks that I can use in the tailstock of my lathe.
None of them are suitable to be used with really small drill bits or very small taps.
So I decided to make a drill chuck that I can hold with my hand and sense what is happening in the workpiece.
