Hi Steve,
Threading the needle shank and having it screw into the needle bar is an
option. I hadn't considered that before, but it would pretty well solve the
extra mass problem. But it would make the needles pretty involved to
manufacture. I'll keep it in mind.

Hi Greg,
Could you use a threaded needle bar and have the needle thread in?
