Finally I realized that I already have a diamond grinding tool, a
drill doctor (model 750, IIRC). It has a little diamond grinding wheel
that is normall yused for sharpening drill bits.

I tried sharpening a tungsten electrode in it and it was completely
easy, painless, did not require me to press it hard against the wheel,
and took me very little time.

It's nice to know that I do not need to buy anything new.

Which way does it put the grinding marks? You have to keep the grinding
marks axial, not radial.

Why? Old welders tale or has anyone actually tried it?

Ask Ernie on sci.engr.joining.welding

I believe radial grinding marks will negatively affect arc stability.

Sigh..ya..Ive tried it. And yes..it makes the arc wander all over the
place if you dont do it axially. I now rough radialy..then turn the
electrode parallel to the wheel and fine point it.

It was driving me nuts and I finally looked it up. Self learning Tig
has been a roller coaster ride.
