FWIW, the reason I was way down at 170C was because my diameter at 180 was in the 1.6 range.  Right now, I'm getting 1.6 - 1.65 ish at 185.

1.6mm filament should still feed fine. The reason the die/nozzle is drilled on the smaller side is to prevent jamming in the printer's hotend if it does swing up to the higher end of the range - some hotends jam with 1.8mm filament, so if I targeted 1.75mm users might experience a jam.

Hi!
After running my filastruder for about 5 hours, I am still seeing metal flakes in the output.  Has anyone else had this problem?

If you are still having issues with this, please contact me at rburnham@osprintingllc.com. Also, what FA# is your machine?

FWIW, the reason I was way down at 170C was because my diameter at 180 was in the 1.6 range.  Right now, I'm getting 1.6 - 1.65 ish at 185.

I still think there could be clogging. Since you're running so slow and cold there isn't much turbulence in the flow to carry debris out.

It's up to you whether you want to try to drill it (1/16" bit) to break up any debris, or take the nozzle off. I'd try drilling first.

Given that I'm getting 6" per minute extrusion rate, what's my best step here?  Disassembly, Drill, more safety pin poking or just let it run and hope it clears out?

A powerful hard drive magnet might serve to deflect the filament enough to make a visible bend in the output.  Or go the fancy electronics route, like the hobby detectors only much smaller. (keep it away from the nipple of course)

...Like I don't have enough problems to solve in my life....
