Open SCAD – Tool Post Grinder!

Please visit for more information on this and many other projects! As in this episode we will be looking at our design up this quick change tool post holder for a small hand grinder! As I have been working on machining couplers for the micro-mill project, I found the need to index grub screw holes so I created this interesting tool post grinder for the mini-lathe and to my surprise this worked out rather well! So I will be working on a larger 555 motor version soon!
