Re: [CAD_CAM_EDM_DRO] R-8 to NEMA-23 Adapter!

Hi Kenneth,

I liked the NEMA-23 holder! I didn't need to grind a motor shaft, but I
do mill flats on them in my Sherline!

I don't think your pen holder will fit on my little Sherline! but I get
the idea. gotta think about it!

Thanks for posting pix!
