It's probably too late now, but the easy way to install the bail is to 
(temporarily) use longer screws to affix the bail and then to replace them, 
one at a time, with the shorter screws, once the bail has been secured.

I wish I could respond as to why they must be manufactured with the pins 
'sprung out'... seems they could just as easily be bent properly from the 
factory. But I'll bet some one WILL be able to offer a logical reason.

>Anybody got a fool-proof, first-time technique for this?

Follow the instructions in the manual. Grasp the IC by its ends, press one 
side down onto the desktop (I often place it against a metal ruler, for 
added ESD protection, though I've NEVER damaged an IC as a result of ESD) 
and roll the IC inward a bit, to reform the leads.

They also make pin straighteners, but they're not all that much better than 
just doing it by hand.

Agreed.
