I posted a message last night about how tungsten electrodes were hard
on regular grinding wheels. I was looking at various expensive tools,
diamond bits that did not quite fit anything that I had, etc.

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?

I believe radial grinding marks will negatively affect arc stability.
