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.

Finally, somebody found a legitimate use for a "Drill Doctor"

I like the Drill Doctor. It does a very good job for me. Unfortunately
it does not sharpen anything smaller then a 3/32 drill. And most of the
drills I use are between #60 and #66. So those I still sharpen by hand,
since they are mostly poorly sharpened right out of the box.

I find sharpening a 1/2" drill by hand a rather tricky proposition to
get it right. The DD does it in seconds.
