My main intention is to save my drill doctor for drills, and to grind
tungsten electrodes with this grinder. Some details are on that page.

The diamond wheel was acquired on eBay.

Would be interesting to know how old this peerless motor is. It says
frame CE12C.

So where do you collect the carcinogenic Thoria dust?

Didn't you see the transparent disk guard with the connector to the
vacuum cleaner? ;-))

I figure that if I use it once or twice a week, there is not that much
danger to me. Still, I will try to fashion some sort of a vacuum
cleaner hose holder of some sort, as well as electrode support.

You don't have to use tungstens with thoria. In fact they are not the
best ones to use.

I have some lanthanated ones. Dangers of thoria, though, should not be
overstated for a weekend warrior like me. I am not production welding
and I am not sharpening tnugstens every 5 minutes. I do it once a
week or so.

Still, I think, I will make some changes to this and will add a shop
vac hose holder of some sort and an adjustable holder.
