Hi
I wear a full plactic face sheild in addition to my safety glasses when
operating the mill or lathe (and it's saved me more than once), but I hate
the way it fogs up all the time. Anyone ever solved that problem?

Also see the January thread about a welding helmet fan, beginning at
http://groups.google.com/group/sci.e...18b527f2dd6df2
A welding helmet fan brings in fresh air to prevent fumes collecting
inside the helmet, but I think it would also drive moist air out and
keep the face shield [note i before e] closer to room temp, for less
condensation.
