Crimped a DB9 connector wrong 3 times before I learned the trick

I keep seeing folks at SATO (San Antonio) smashing pins on those old 9-pin serial connectors like they're trying to win a fight. The issue is they're not using the proper crimper or they're stripping too much jacket off, which causes shorts. I finally watched a 5-minute video from a retired Navy tech and it clicked - you gotta stagger your pins in the hood before crimping. Has anyone else found a better way to not wreck these things on the bench?

You ever notice how some things in tech just feel like they were designed to mess with you on purpose? I had a buddy who spent an entire afternoon trying to get one of those DB9 connectors right and ended up snapping the plastic hood in half out of frustration. He finally just taped the whole mess together with electrical tape and called it good enough. That bootleg fix probably still works to this day in some forgotten server room somewhere, haha.

Lmao yeah that staggered pin thing was a game changer for me too. I think I ruined like 4 connectors before someone finally showed me one of those tutorials from a retired military guy. Honestly felt like I was being hazed by the hardware.

That "stagger your pins in the hood" trick is a lifesaver, I wish I had known it years ago. I've definitely been in your shoes, sitting there staring at a mangled connector wondering where I went wrong. It's one of those little things that makes all the difference once you finally see it done right.
