Recently I purchased a drill doctor as MSC had them on special offer and although I can free hand sharpen drills but have good and bad days and find smaller sizes a bit of a pain.
Playing around with it I thought of the possibility of using it to sharpen Tungsten electrodes for tig welding
So I made up a plastic adaptor to go into the position used for reliving the drill point
I drilled a 2.4mm hole through it at about 15 degrees offset to the centre line .
Inserted a 2.4 mm electrode into the hole and set the plastic adaptor so the electrode would make contact with the diamond grinding wheel .
I made the adaptor so that it is a tight fit in the hole in the drill doctor .
Then turned the electrode with a pin chuck .
The result is very passable Mike
