I've opened the small handful of OC5's that I've encountered so far...
but to be fair, I've NOT spun an 0402. It's quite possible the smaller
fence and smaller dial could pose some difficulties.
Friction fence locks are a different ball game for sure. But they're
well worth your time in getting acquainted with 'em, as they open
the door to many other 'oldie-but-goodie' locks! The OC5, in my
opinion, is a nice intro to the difficult 'oldies' to come - much like
the S&G 6730 serves as an intro to learning manipulation.
As Martin & Visitor mentioned, I too would recommend getting an amp.
And not necessarily for just this lock - but just in general - you're going
to want one. It doesn't have to be a high-end one to be affective either.
$100-150 will get ya a perfectly decent amp. Sometimes an amp can be
useful... other times it's absolutely crucial for an opening.
I'm no authority on friction fences, lol... a handful of locks is practically
no experience at all. But I'm more than happy to tryn' convey what I do
know of spinnin' em. Mount yours up, give it a good spin session, and we
can always talk more about it if you'd like.

I guess so then. Of the Yale dials I have here, all measure 2.5"
