Thanks for the comments regarding reversing the grinder wheel direction. I hadn't thought of the possibility of bending the tungsten. However if I get to the project I still might try having the guide as close to the wheel as possible. A shorter projection should lessen the chance of bending and I would have a better view of the sharpening process. This would be a project for the future because I've got a few retirement, (26 years come Sept.), projects to get to first. I've had good luck sharpening the tungsten on a very fine green wheel that I use to sharpen carbide cutters.

NICE WORK, both the prototype and updates. My one thought thru the whole process: Is there a way to reverse the rotation of the grinder? If not, I thought that I would buy a cheap 6" bench grinder, see if the rotation can be reversed and, if not, see if the guards could be reversed and the grinder turned backwards to accomplish having the wheel turn AWAY from the electrode end thus eliminating the chance for kick back. This may require mods. to the debris outlets as well but that shouldn't be a game changer.
