Just trying to help here... but hopefully you are still holding the
tungsten so that the grind marks are parallel to the tungsten it's
self?

If your grind marks are going around the tungsten as opposed to inline
with it you will have a variety of problems.

Really?
I'm not a welder, but I play one in the shop. I've always ground mine in a
drill chuck too. What kind of problems am I creating for myself?
