TIG electrode holder for grinding

[tachetailleur]

Thank you for the video, I found it very interesting. I have a similar problem of sharpening short electrodes (cheaply!) and I had the idea of using the torch collets to hold them in a suitable housing (the logic was that you wouldn't need to sharpen anything shorter and collets are readily available). A modified torch might have worked but I didn't have one to sacrifice. I made something from a piece of rod and a machine screw modified on the lathe. Anyway, although it seemed to hold the tungsten quite firmly it didn't have enough clamping force to stop it being moved during grinding, which was a bit disappointing...I'm making the comment in case anyone else goes down that road.
I took some photos. The item on the left is a piece of tube with a tab welded to it. That was to be fixed or held to help keep the correct angle.
