Well, I've been looking around for a week.
Color me stupid, but I'm going to go for a speedglas. Probably not cost effective for a hobbyist.
I may have to live off of top ramen and roadkill for a week or two, but what the hell.
It never occured to me that failure means the glass not darkening.
Having burnt my many eyes by being stupid years ago, I don't want lightning to strike twice (pun).
What is funny is I have accumulated no less than a half dozen fixed glass hoods over the years. WTF is that about?
