Just ordered an OBM Surface Grinder attachment for my KMG. I used to have access to a fully automated surface grinder where I used to live. Well, I still have access to it but it's 2 hours away. I'll tell you that machine spoiled the crap out of me. Set it up, push the button and go have a cup of coffee. I wish I could get a full size surface grinder into my shop but it would take some professional riggers to make that happen. I know the OBM does not compare to an actual surface grinder but I truly believe it will do what I need it to do. I will post some pics and maybe a video when I get it.
