Oh man, I gotta push back a little on the zip tie thing. Honestly, you're not wrong about overtightening being a problem, but the real issue is using them wrong in the first place. I've seen people crank zip ties down like they're securing a car battery, and yeah, that'll crush any cable. But if you just snug them up enough to hold the bundle together without crushing, they're totally fine. The trick is to leave a little gap so you can still slide the cables around inside the tie if you need to. Velcro is definitely more forgiving, especially if you're always rearranging stuff, but zip ties aren't cable killers if you're not a gorilla with them.

Nah, pretty welds matter too if you know what you're doing.

Why are we acting like clamping harder is ALWAYS a bad thing? I've been doing this 20 years and sometimes you NEED that extra squeeze to keep thin wall stuff from chattering. If your parts are coming out .002 oversized, maybe your tooling is dull or your speeds are off, not the vise pressure. I clamp the hell out of stainless all the time and never get warpage because I check my setup with a test indicator before every cut.

@brian_kelly91 coax is actually 50 ohm, so impacts wreck the impedance for sure.

Wait, a French soldier just found it digging a foundation? That's insane. I always pictured some dusty archaeologist in a tomb, not a guy trying to put in a support wall.
