I think I read a nasa or military thing one time that said use a cocktail stick ,or some thing of equivalent diameter to bend the component leads around , apparently its better with a little radius on the bend than than sharp square right angle , as there would be less stress /fatigue in the lead material . I guess those guys noticed how things could fail under extreme conditions , of vibration and g force. Ive seen a little gadget on fleabay , its a plastic lead former with graduated lead lenght and the appropriate radius bend . I find the shaft of a precision screw driver the most convenient thing to use , but on some ocassions particularly if the lead wire is heavy duty I do as PRR described .
