    Then stabilize it with one hand or clamp it to the table. Seriously though, the low torque motor plus the speed of the small diameter disc make this a simple task. I don't think I can make the unit catch the electrode if I tried.

        That's why I don't like them. It's like having a bench grinder running off a car battery...it has such low power that when you hit tungsten to it, it slows down. I'd rather have a big bench grinder where I don't have to go easy on it to keep from slowing it down.

            So after all the talk about the bench grinders in another post (sorry for getting off topic BTW), and how I hate my current like new Craftsman "Pro" 8" bench grinder, I looked into getting another grinder, and did Friday evening. I am posting this hoping to help others on this decision.
            I picked up a , cough, cough, Harbor Freight tool grinder. I know, I hate buying from them, and I hate buying Chinese junk, BUT... as I found, this is my second favorite tool I bought from them (the first is my bodywork stud welder). Seriously, this 110# machine is stout, and runs VERY smooth. It comes with Silicon Carbide wheels, which could easily be replaced with diamond if needed. I found that they did not wear appreciably using it this weekend on Tungsten (that is what I bought it for), especially not compared to the Alum Oxide on my other grinder. The bench is sturdy to rest against, and I think that making a jig to hold the tungsten at a fixed angle relative to the wheel should be easy. It really is smooth running, with minimal vibration, and works as well as the Baldor tool grinder we used to have at work. I was pleasantly suprised.
            Now, the best part, it only cost slightly more than my crappy grinder after the 20% off coupon. In the store it was $160. Online is $130, so they marked it down to the online price. Then, using the 20% off, it became $104. Heck of a deal IMHO.
            Maybe this would be a good alternative. Eventually, when I get a lathe, it will come in handy also.

                You don't really have to grind yout electrode do you. I have a hard time believing that you dip your tungstens
