I try and try to grind my tungstens without contaminating them but sooner or later the wheel I use on my pedestal grinder with the "tungsten only" stone on it get used for other metal too. Well, I decided I wanted a tungsten grinder that I can have right next to me when I need it.
I could buy one of these really nice HTP handheld pieces for $230+ but I'm cheap.
Or I could spend $50 and 15 minutes to build something portable and simple that would do a good job out of these three cheap pieces from HF.
Trim grinder arbor on the lathe to fit the diamond wheel. You could just file the hole on the diamond wheel to fit the arbor if you don't have access to a lathe.
Drill a couple different size holes for your tungstens in the grinder guard. Make sure you run the drill bit at an angle once you drill through the material so you can angle the tungsten so the grind marks run longitudinally (towards the point). I use the router rheostat to dial down the rpm on the grinder a bit.
Some results. Just need some adjustments to get exactly what I need.
