How is that even possible, though? Imagine the threads in the halves, with a bearing in-between as a “tunnel”. The axle would have to be longer than this “tunnel” in order for that to happen. You could be the strongest person in the world and tighten your hardest, and at a certain point it just can’t tighten anymore and the threads will strip.
You can overtighten with certain plastic yoyos because of their spacer and axle systems. But for just tapped aluminum halves, unless the axle gets somehow “stuck” (usually cross-threading) in one half before it has gone to maximum depth, you just can’t mathematically do it.
We were actually at a yyf class, so Tyler Severance was able to explain it. I don’t know if its actually this problem, but I believe the earlier shutters actually had too long axels that could be overtightened and sort of go through the side.

Aight. I’ll chalk it up to bad design then.
Yep, I’ve got one of these with the exact same issue. Doesn’t seem to affect play though. Mine was a first run shutter too.
exact same thing happened to mine. except mine vibed afterwards.
There should be a full millimetre of “wiggle room” to avoid this happening.
