I'm gonna ride this frame.
Yay! I'm not a framebuilder, but there shouldn't be (that much) danger in riding this thing, right? The steerer and headset will hold the head tube together, and you can just keep an eye on the top tube. Maybe you could braze a fancy gusset between the top tube and head tube if you had reason to be concerned at some point.
