Topic: Word of Warning - Barrel Tightness
My Beta v2 Filastruder would never completely clean out. There would still be filings showing up every few inches, no matter how long it had run, and every now and then it would make a groaning sound, like the auger was dragging on the pipe. I took it apart to clean it out after trying coloring with powdered pigment, and found out the source of the contamination-
So when screwing on the nipple, be careful not to twist it too hard because you can bend it just enough to cause a problem without being able to see that it's bent. It's a bit of a dilemma, because if it isn't tight, it might rotate and turn the hopper opening sideways. So it is probably best to get it mostly tight, and then accept that the auger will twist it more and force you to turn the flange back 90 degrees.
