Mini-Lathe Tool Post Grinder!

While working on machining couplers for the micro-mill project, I found the need to index grub screw holes so I designed up this quick change tool post holder for a small hand grinder! To my surprise this worked out rather well! So I will be working on a larger 555 motor version soon!
