Honestly? Way too much fuss over sigma settings. Defaults work fine for most shots. If you're losing faint stuff, your data might just be weak to begin with. Saw @wren115's post and yeah, it helps, but it's not magic. People act like tweaking a number is the secret key. It's just cleaning up the mess, not fixing a bad capture. Spend less time on sliders and more on getting good subs.

My cheap saw shot a tile chip into my forehead, so I feel your pain.

It's funny how we call it paranoia until something actually goes wrong. I see it all the time with small safety steps people skip, like not securing that parchment paper.

Guess that's why my old fence looks like modern art now...

Honestly seems like overthinking it. Just twist the wires tight and use any decent nut. Never had a problem that way.
