My first blade sketch

Yep getting old over here, failing memory ;0)

I was probably in my 20's when I seen the show using that tool and I thought Norm used a regular drill press

Norm did use a regular drill press. It had an attachment that allowed the special bit to work, which works fine but is a PIA to change and set up every time you need it. I was working on a gazillion flutes that had square holes for the sound hole so the dedicated machine was worth my investment. I have since used the tool twice...
